instrumental level. Which building level is better: how to choose control and measuring devices. Best little bubble levels

The building level is a tool that detects the slope of surfaces. Suitable for indoor and outdoor use.

How they work

The algorithm of operation of any of them is reduced to the choice of the installation point and the place for measuring the level. The remaining options depend on the particular type of tool and can be combined.

The building level helps:

Determine the verticality or horizontality of a given surface - in order to establish a further scope of work and its necessity.
To find out in which direction the tilt occurred, in some models its exact size is also available.
Set clear guidelines when marking surfaces - before installing frames or furniture.
Calculate the volume of materials - for this, the arithmetic mean of the levels of different points on the same surface is used.
Determine a single level in different rooms - often required when installing ceilings or windows.

In low-rise construction or apartment renovation, manual tool variations are more often used. These are devices without complex electronics that do not require special skills. Professionals use several types at the same time.

Types and functions of building levels

hydraulic levels

The functioning of this type of instrument is based on the law of physics about communicating vessels. Structurally, hydraulic levels are two flasks connected by a transparent tube.

Peculiarities:

This is an accurate view of the levels, but it is important to keep the hose free of kinks and have good eyesight.
Suitable for checking slopes simultaneously in different rooms.
As a rule, they require pair work.

To bring the device into working condition, it is enough to fill it with water so that the upper meniscus of the liquid reaches the middle of both flasks, and no air bubbles remain in the tube.

Bubble building levels

Regardless of the size and design features, the principle of the device is the same. At least two flasks are built into the body of the level, where small air bubbles “float” in the liquid. Focusing on them, they check if there is a slope of the planes.

Peculiarities:

The liquid in most cases will be technical alcohol. Allows you to measure with an accuracy of 1 mm / m - this is the industry standard.
"Air" bubbles of solid acrylic suggest greater precision. Accuracy 0.5 mm/m.

Some models of bubble levels are equipped with flasks on a rotating base. This allows you to work with inclined planes. Profile shapes are in the form of a box, a trapezoid and with one measuring plane cast Shark (shark). Part of the tool is equipped with end elements that prevent breakage during falls.

Laser building levels

The convenience of this equipment lies in the non-contact use and in a large area of marking coverage.

Peculiarities:

The pendulum of devices is leveled after unlocking. It is desirable to set the base plane horizontally.
Manufacturers offer an additional mounting tripod, but its dimensions are not enough for marking at a height. In this case, a bar is used, which is fixed between the floor and another horizontal surface. The platform on which the tool is installed moves along it.
In bright light, the laser beam is not visible to the naked eye. To resolve the issue, glasses with glasses in the red color range are used.

Part of the laser levels produces static vertical and horizontal lines in a limited sector. An alternative option using a dot running in a circle allows marking from all sides simultaneously.

Magnetic building levels

Magnetic levels are visually indistinguishable from bubble levels. The difference is noticeable only on the lower ends. This option is equipped with magnets for easy work with metal surfaces.

Peculiarities:

Bar magnets are more commonly used in polymer levels, in combination with a V-groove for ease of use on pipelines.
Ceramic magnets or ferrites have been the industry standard in levels up until recent years.
Rare earth - most aluminum models now come with this type of magnet. They are up to 10 times stronger than ceramic.

This type of level is more often used for works related to the installation of frames for drywall, as it is conveniently attached to ceiling and rack profiles, leaving hands free.

Optical building levels

An optical level or level is used in industrial facilities or in the construction of houses. The kit includes a special tripod, without which the use of the instrument is unproductive. Installation comes down to mounting, focusing and centering.

Peculiarities:

Centering is needed for point-to-point measurements. It is carried out using a construction plumb line attached to the bottom of the tripod.
Focusing - the telescope is aimed at the rail, with the help of an adjusting screw, the clarity is adjusted. The eyepiece ring defines the reticle.

After adjustment, the height marks are taken. The collected data are summarized, their arithmetic mean is calculated. It will be the mark of the base from the horizon of the instrument.

Advantages

Each type has its own set of advantages:

hydraulic levels . They support measurements in different rooms, when the initial level is hidden by partitions or heavy structures. This functionality is not available in other models.
Bubble . Easy to install and use, light weight and dimensions. Possibility of use for measuring the level and at the same time checking the plane of the wall or floor.
Magnetic . Do not require additional fixation when working with metal. They have a full set of advantages of bubble models.
Laser . Supports simultaneous vertical and horizontal measurements. The coverage range is higher than any of the manual models. Automation of routine processes.
Optical . Applicability in open spaces, in the construction of roads and large facilities. Functionality, saving time and labor costs. When measuring at a distance, the accuracy does not decrease.

Problems

Disadvantages and inconveniences also depend on the type of tool:

Hydro. M obscure and difficult to use. The routine processes of filling, draining, unwinding and forcing out bubbles are time consuming. Not suitable for vertical planes.
Bubble . Often goes astray, adjustment is often not available. Not suitable for work over long distances and areas. In adjacent rooms, the correct level cannot be determined.
Magnetic . The same disadvantages as the bubble. Magnets often protrude from the plane of the rib - when measuring, fresh paint or putty can be damaged. Some models are less stable than bubble ones. Frequent failure of magnets is also a disadvantage.
laser . Requires a flat surface. The pendulum during transportation often fails. With distance, the diameter of the beam increases, which affects the accuracy. Plane measurements can only be made using optional accessories.
Optic . Adjustment is time consuming and requires skill. For domestic purposes, the functionality is redundant - neither the time costs nor the costs are justified.

How to choose a building level

For most types of levels, accuracy will be the defining indicator, so checking its correctness is important.

bubble and magnetic

The same design also implies uniform methods for assessing the correctness of indications.

To check a horizontal flask, you need:

Place the tool on a flat surface.
Make two marks: at the end of the level and along - near the horizontal ampoule.
Note the position of the air bubble.
Turn the spirit level 180° and set in the same place according to the previously made marks.
Check the position of the air bubble. Any difference in its position before and after the level flip indicates that the instrument is inaccurate.
Repeat the test even if the readings match.

To check a vertical flask, set the level on a door frame or a flat wall, further steps are similar to horizontal measurements.

Hydro

In this type of measuring instruments there are no structural details responsible for the accuracy of measurements, but there are nuances that should be considered when choosing:

The length of the hose - you should not choose it in reserve, because the extrusion of air bubbles and the straightening of the tubes can turn this advantage into a problem.
Pay attention to the tightness of the protective caps. Water should not pour out - this will interfere with work.
It is worth checking the integrity of the tube and the connections with the flasks.

An additional parameter is the flexibility of the hose, but it is difficult to evaluate it without having experience with this type of level.

laser

The choice of a laser level involves reconciliation of a number of indicators:

Measurement error - should not exceed 3 mm per 10 meters.
Self-alignment - test multiple models. The preferred option is the pendulum of which levels out faster than in analogues.
Range - marked as a radius or diameter. To avoid confusion, specify what type of distance is indicated. The laser is responsible for the same parameter. The 532nM green beam is suitable for most measurements.

In addition, the integrity of the instrument and the absence of mechanical damage are checked.

Optic

You need to choose a level taking into account the tasks ahead and the features of future use. They are divided into three classes: high-precision, basic and technical.

Peculiarities:

An air damper is suitable for outdoor applications, while vibration mode requires the use of a magnetic version.
To perform tasks in a limited space, the defining parameter should be the smallest sighting distance. For large objects, models with the maximum magnification range of the telescope are preferred.
Class I or II leveling at construction sites is usually not required, but it should be borne in mind that only high-precision instruments are capable of performing it.
It is easier to prepare a tool with a compensator for work due to the self-alignment of the sighting axis.

Which is better

The answers to these questions will help you choose the best type of tool for your current tasks.

What basic functions should the level perform?

The functionality of the bubble level will cover all the problems of household tiling, but it is impossible for them to correctly measure the level of ceilings in different rooms.
Laser - will save hours of work on marking walls for frames and wallpapers, but is not suitable for determining the correct level of the planes.
Optical - will support accurate calculations for laying tracks, leveling surfaces, but it will not work to hang shelves inside a kitchen cabinet.
Hydro - will help to perform a single marking of ceilings, but it is useless for mounting wall frames.

Where will it be used? Indoors, outdoors, or both?

Most of the electronic models are not designed to work outdoors or in aggressive environments (rain, snow).
Please note that in addition to the laser level, you will need an outdoor detector, as the beams will not be visible in daylight.

What is the required measurement accuracy?

Industrial lasers and levels have mechanical or digital counters, there is support for recording the angle of inclination in 0.01% increments. For less accurate measurements, basic models of hand tools are selected.

Are additional features needed?

A professional-grade tool, accessories necessary for comfortable work. But the functionality of household and industrial models may not have significant differences.

How to use the building level

Features of use depend on the type of tool. There are no single operating methods.

How to use the hydraulic level

Carefully unroll the tubes and fill the instrument with clean, running water through one of the flasks while holding the other one above. Try to fill without stopping so that there are no extra air gaps.
Check the correct filling - the tubes should be evenly convex. Drive the rest of the air bubbles with light clicks to the flasks until completely out. If done correctly, the risks will rise to the same height when measured. This can be checked by placing the flasks close to each other.
Lock the lids.
The next step is to work together. One person holds the flask, and the second goes with a hose to a place or room, the level of which needs to be compared with the current one.
When both are in place, the caps are removed from the flasks. It is important to do everything at the same time and at approximately the same height - otherwise there will be overflows.
One person holds the flask against a pre-made mark, making sure that the center of the meniscus of the water corresponds to it.
The partner carefully raises or lowers the flask, thereby adjusting the level of filling with water.
When everything is leveled, a level mark is made by the second participant.

Precautions: avoid kinks and mechanical damage to the hose.

How to use the bubble and magnetic level

Place the instrument on the surface of the object whose horizontality is to be checked.
If the air bubble is to the right of the line, the object is tilted down to the left.
If the bubble is to the left of the line, the object is tilted down to the right.

The vertical level is found by analogy.

Maintenance and care consist in the timely cleaning of the instrument, especially after measurements on wet plaster surfaces.

Precautions are limited to protecting the instrument from bumps and falls.

How to use the laser level

Place the instrument on a tripod or a flat surface.
If the model is manual, make sure the bubbles indicate the level. Otherwise, find the screws on the side and adjust them to the required correctness. Self-Leveling - Allow the tool to self-level after installation, typically 30 seconds.
Turn on the device. The device will emit a beam that reflects on surfaces. Depending on the type of laser level, it can be a dot, a line, or several horizontal or vertical intersections.

If the device has not been used for a long time or has been dropped, calibration will be required. Mounting on a rail or tripod is carried out using a clamp or clamps from the kit.

Precautionary measures:

do not look at the beam itself, do not direct it at children or animals;
do not use the tool in the rain;
do not carry with an unlocked pendulum - many models warn about this with a beep or laser blinking.

How to use the optical level

Before use, check the stability of the tripod. Tighten the mount with the tool. Make sure the foot screws are not too tight on the footing.

Alignment:

Hold the adjusting screws between your thumb and forefinger and turn them simultaneously in opposite directions. Observe the movement in the graduated flask.
The air bubble should be centered on the circular level window.
Centering on a point is carried out by a plumb line mounted on a tripod screw. Then the level is shifted along the head.
Centering is complete when the plumb bob is above the target point.

Focusing:

Aim the telescope at a sheet of paper or other light object.
Tighten the eyepiece until the desired sharpness appears - the sight should be clear.
With the tube pointed at the supplied rail, adjust the focus with the knob.
When properly adjusted, the scale of the leveling staff and the crosshair of the sight do not move one after the other.
After focusing, hold the level on a specific target.

Use the focus knob to add sharpness.

Precautions are the same as for laser models, but additional care must be taken when handling the lens.

Warranty

Standard warranty obligations exclude cases of mechanical damage.

Bubble, magnetic and hydro - related to hand tools. They rarely have warranties longer than 12 months. Most manufacturers do not provide detailed conditions for these types of tools.

Laser - depending on the manufacturer and the category of the tool (household or professional), a guarantee is provided from 1 to 3 years.

Optical - standard warranty period of one year. But the narrowness of the niche forces manufacturers to go to tricks. Some give a guarantee on the tool up to 25 years.

The warranty period can be counted from the date of purchase or shipment. In the second case, it is appropriate to clarify how much time the tool spent in the warehouse.

Faults and repairs

Different parts turn out to be weak links - their set depends on the type of tool.

Bubble and magnetic

The main problem is related to the loss of measurement accuracy.

Broken flask with bubble - the readings will no longer be accurate, the error can reach several cm per meter. In budget models, bulb adjustment is not provided - the tool is unsuitable for work with this malfunction. In other cases, tightening the screw fasteners or fixing clips will return the level to the correctness of the readings. During setup, calibration is performed in the same way as when selecting a tool.
Bent profile - this happens with bumps and falls. The tool cannot be repaired, it will no longer give accurate readings.
Crack in the protective glass of the flask - in models of a collapsible type, the part changes to an analogue. Solid cast levels in this case cannot be repaired.

Minor problems: breakage of protective pads and handles, falling off of magnets are corrected by replacing the obsolete part with a new one.

hydraulic levels

Malfunctions of hydraulic levels are reduced to three types:

Broken or cracked hose . Occurs as a result of mechanical damage or freezing of an instrument filled with water. As a temporary measure, you can seal it with a layer of nail polish and wrap it with electrical tape. Complete repair and replacement of the hose is often unprofitable - the costs are comparable to the acquisition of a new hydraulic level.
Cracks in flasks - temporary measures are similar to those presented in the previous paragraph, but instead of electrical tape there should be a transparent material in order to see the rizki. Replacement may not be required in mild cases. In serious cases, it is necessary to change, since the defect will affect the accuracy of the instrument.
Breakage or loss of protective caps is the simplest case. They can be replaced with plastic soda caps.

Laser

Correction is often impossible to perform independently due to the need for a special tool.

pendulum shift - the tool does not work correctly, with deviations in horizontal and vertical measurements. This happens after the device falls or is carried with an unlocked pendulum. Restoration will require an offset adjustment. Such damage is not covered by the warranty.
Beam does not burn - the malfunction is caused by a broken wiring or incorrect operation of the batteries. In the first case, you will need to remove the cover of the device and replace the flexible wiring going to the pendulum. In the second case, unclenching and stripping contacts or changing batteries is more often enough. Both options are self-repairable.
Instability of readings - as a rule, it will be necessary to change the suspension bearing. The case is rare, but guaranteed in the absence of mechanical damage.
Buttons don't work - there are several options for failure, of which only clogging of contacts can be repaired independently. The keyboard may not work as a result of frequent use in dusty environments. Clogged contacts will need to be cleaned mechanically. The procedure can be performed at home.

In difficult cases, the keyboard will need to be replaced. When the coating is membrane, it will not be possible to repair the device without special skills.

Optical

Problems of optical levels are solved systematically or by replacing parts. Repair with improvised tools is often not applicable.

Sticking compensator - to solve the problem, the standard calibration procedure is performed several times. In case of gross errors, service maintenance of the tool will be required.
Cracked lens or mirror . Purchase of a similar part is required. The optical lens can be replaced by yourself.
Adjustment is broken - you need to calibrate the device. The screw fastener is loosened, the plate with the grid is aligned. To do this, the horizontal thread is placed perpendicular to the axis of rotation of the tool, and the vertical thread is set along the plumb line.

Problems in the operation of electronics, serious mechanical damage, site repair or torsion bars will require the intervention of specialists.

Types of building levels

You can buy a building level from us:

Bubble. A special tool of rectangular shape with installed transparent flasks filled with liquid. By the location of the bubble, it is easy to determine whether the surface corresponds to a horizontal or vertical plane. The presence of the third flask makes it possible to measure the degree of deviation from the given parameters of the horizon. The catalog contains levels of various lengths and body designs: "Profile", "Rail", etc.

Water - a special construction tool. The level is designed to determine the horizontal location of structures or distant objects. Two graduated flasks at the ends of the hose filled with water allow you to quickly and accurately beat off the horizontal level of the foundation, screed, floor, etc.

The photographs accompanying each model, as well as an informative description, will help you choose the right level. It is enough to go to the site page and you can find out everything about the possibilities, advantages and distinctive features of a particular model.

Depending on the type of tool, manufacturer and individual characteristics, the price for the construction level may be different. Along with professional, more expensive products, we also have budget models that compare favorably with affordable prices and high quality.

For accurate and quick measurements, buy building levels in Skladom!

Bubble level is an indispensable tool for construction and repair work of various types. This device helps to create straight lines in any plane, check the necessary slope or angles. The progenitors of building levels are plumb lines and spirit levels, the functions of which they, in fact, perform. Levels are indispensable when laying pipes and various surfaces that are demanding on the angle of inclination. They are used during the installation of equipment that vibrates during operation and is demanding on the evenness of the installation surface. The arrangement of sewers or steps is also not complete without this tool. Building levels are in the arsenal of any master and are a necessary thing in the household, so it is important to know how to choose the right building level.

bubble level design

The building bubble level is a fairly simple but functional design. It is based on a bar made of solid material, in which a number of air ampoules are mounted. Measuring marks are applied to the ampoule, which determine the position of the air inside it. It is this indicator that is the key to the work of the level. When the bubble is exactly in the middle, this means that the surface is perfectly flat. To check inclined surfaces, an indicator of air deviation relative to the center of the ampoule is used.

The main and most important part of the level is an ampoule with a liquid in which air floats. If the integrity of this part is violated, then the entire device is considered unusable. The filling of the ampoule is most often technical alcohol. For ease of use, manufacturers modify the level, some models are equipped with a lens that allows the worker to better see the bubble. To work at night, fluorescent additives are added to the liquid, which help to use the device without additional lighting with their glow. In such improved models, the ampoule with all the additives is called the eye.

Shockproof models have become quite popular. During work at a construction site or during transportation of the device, unpleasant incidents often occur - falls, shakes, mechanical damage that disable the level. Longer models are especially prone to breakage, as their size makes them more likely to fall and makes the impact force stronger than short frame models. At this level, the building price is slightly higher than for conventional models. However, buying a shockproof device is still more profitable than regularly replacing damaged ones with new ones.

The base is equally important in the whole structure. It consists of wooden, plastic or aluminum slats. Wooden planks are made solid, aluminum or plastic hollow. Most often there are levels with an aluminum base. When choosing a device, pay attention to its weight, since the heavier the device, the better its readings. Practitioners among all the modifications distinguish the cruciform design with rubber handles. They call such levels the most convenient and accurate. For working with metal surfaces, it is recommended to use devices equipped with magnets. Another optional but handy addition is a ruler on the long side of the level. Such a modification will help out when carrying out measuring work and eliminate the need to carry a ruler or tape measure.

The simplest and most primitive level model has only one measuring ampoule. But such modifications are quite difficult to find in a modern store. Manufacturers offer a larger range of levels with two or three ampoules. One of the containers is located on the long wide side and is designed to work in a horizontal plane. The second container is located on the narrow short side of the device, perpendicular to the first. It is designed to work in a vertical plane. If there is another container on the bar, then it is also located on the narrow part, but on the reverse side. They fix it at an angle of 45o, and the purpose of this ampoule is to control the operation of the device.

Manufacturers offer bubble levels not only in different versions, but also in various lengths. The shortest standard model has a length of 20 cm, the longest - 3-4 m. This indicator determines the functional purpose of the level. To install various household appliances and perform simple repair tasks in a private house or apartment, it is enough to use small levels. When laying tiles or working with various finishing materials of this type, a length from 40 cm to 1 m is optimal. Long building levels are professional, used when carrying out major construction and repair work. Experts note that the longer the level, the more accurate its readings.

What to look for when buying a bubble level

Building levels are one of the most popular products from manufacturers of cheap and low-quality products. Since this product is used not only by professional builders who know exactly what they need, but also by ordinary people. The manufacturing technology of the building level is not so complicated, but it requires precision and the use of quality materials in order for the device to work properly. Unfortunately, manufacturers of fakes and low-quality goods take advantage of the ignorance of unskilled people in matters of construction and offer low-quality products, the readings of which are not accurate. Trademarks that have already established themselves as responsible manufacturers of building levels:

Kapro

Stabila
Ermak
Bosch
Gross Laser
Shark (Israel)
Leader

But, even focusing on these names, it is not always possible to buy a high-quality and durable building level. You need to know some of the nuances of choosing this device, as well as be able to determine the required model so as not to overpay extra money for a professional level if it is needed only for small household work.

To begin with, they are determined with the required length of the tool. To do this, determine the goals and objectives that are set before him. For finishing work and leveling surfaces, you will need a device of great length. For small decorative works - installation of hanging furniture, shelves, switches, paintings, the level of small or medium sizes will suffice. The best option for domestic use is a level 50-60 cm long.

During the selection, carefully inspect all the glass elements of the device. We are talking about containers with air, which perform the main function. First of all, they must be intact and not have traces of mechanical impact. Next, the strength of their fastening is checked, these parts are fixed tightly and should not stagger or unscrew. There are models with the ability to adjust capacities, the presence of this function is a very controversial point. On the one hand, the adjustment allows you to adjust the failed level, on the other hand, it makes the device more vulnerable to shocks and mechanical stress. Professional builders recommend purchasing levels with a rigid fixation of all containers.
After examining the fixation of the flask, pay attention to the air itself in it and the strips applied to the surface. All these elements should be clearly visible and located close to each other. The best option is the location of the control strips inside the vial, and not on its outer surface. Since with active use, these marks will quickly be erased.
The next important factor is the base material of the level. Whether it is made of wood, plastic or metal, it must be heavy and durable. Optimal models with stiffeners located inside. In general, the design and external construction of the levels differs for each manufacturer, but this aspect does not affect the accuracy of the device itself.
After an external inspection of the level, it must be checked. Specialized stores should always have a stand to test the device, which has a perfectly flat surface. But even if there is no such stand, it is not difficult to check the level in any other place. To do this, it is placed in a horizontal plane and the position of the air bubble is marked. Even if it deviates from the center, this is not scary, since this is not the essence of this check. Then the level is raised, turned 180o and placed exactly in the same place. In this case, the position of the bubble should be at the same mark. If so, then the device is OK.
The accuracy of the indication of a flat plane without the presence of a verified surface is impossible. But in this situation, it is enough to keep the receipt from the goods and then check the level readings using other devices. For example, for this they use a level or a laser level, or a bubble level, which has already proven its indications. These checks must be carried out even with branded and expensive items, since during transportation the technical characteristics and indications of the device are often violated.

How to set up a bubble level

The bubble level setting is only possible if a model with loose containers is available. The level setting process is quite simple:

The most even wall in the room is determined, this area should be at eye level, while the corner is located on the left side.

Stepping back from the corner about 4 cm, they drive in a nail or twist a self-tapping screw. They do this not to the end, but so that 2-3 cm remain on the surface.
The device is placed with one side on the nail and leaned against the wall, and then adjusted so that the air in the container shows a flat surface. A line is drawn along the edge of the level on the wall.
Turn the device over and repeat the procedure.

The correctness of the setting is checked by the drawn lines, if they do not go beyond each other, then the device is functioning properly and its readings are accurate. If the marked marks diverged, then proceed as follows:

On the right side, where the marks end, mark the center point between them.
The device is placed again on the nail, and the other end is applied to the marked point.
For convenience, another self-tapping screw is screwed into the mark, or simply hold the level with your hand.
In the fixed position, the liquid container is adjusted to the required position.

In the same way, the container is adjusted to work in a vertical plane, only the level is pressed against the nail with the long side.

How to work with a bubble level

When working with a building level, it is important to remember that this device has a working surface, with which it is applied to the control area. This area is distinguished by a raw edge or a magnetic insert. In some models, there is no distinction between the work surface and other faces. If you put the device on the other side during use, it will not harm it, but the measurement accuracy will drop. The level is never laid sideways, all measurements made in this way are not correct, since, in fact, a non-existent surface is measured.

To work in a horizontal plane, they are guided by a container in the long side of the level. The device is applied to the surface and a line is marked in which the air is exactly in the center of the ampoule. If there is a deviation to the left, then slightly lower the left edge of the frame or raise the right one. The same is true for deviations to the right.

To work in the vertical plane, they are guided by the container in the narrow edge of the device. For example, if it is necessary to control the quality of the wall finish, then the device is applied to it with the capacity up. If the air moves away from the wall, there is a convex unevenness from below. If the air moves towards the wall, then it means that you need to add a little volume below the level.

When buying a building level, you need to carefully study it. But in order to study it, you need to know what to study.

First of all, you need to pay attention to how the flask with the bubble is located. It should be absolutely flat without any bends. If there is even the slightest error, then during the construction it can greatly hinder.

Secondly, if you buy a level in the store, you need to immediately test it. Bring it to the wall, floor. You need to make sure the level is showing correctly.

I will tell you about one good way, how not to make a mistake when choosing a building level, which I always use myself. It is necessary to put it on some flat surface and mark marks on this surface with a marker (pen, pencil), as it stands.

After that, you need to turn it 180 degrees and put it in the same positions according to the marked marks. If the bubble in the flask is in the same position as it was before, then the level is correct.

You need to do the same for the vertical level. In the same way we put it against the wall, the bubble should be in the middle. Turn over and put in the same positions. If the bubble is in the same place, then the tool is working.

You should not skimp on a construction tool, as most cheap levels easily bend, which will be inconvenient when working.

It is necessary to choose a fairly weighty level, it should not consist of some kind of light material.
The bubble should move smoothly when tilted, without jerks and delays.
There should be no foreign objects or debris in the vial.
The body must be thick enough.
The walls should be about 3mm.
If you are working at height, then you need to buy a level with a magnetic stripe. Since it will be very convenient to magnetize it to the surface and you will have free hands.

The level must be treated carefully enough, it is afraid of falls, since the bubble may deviate.

A bubble level is essential for fine and small work. For larger jobs, you need to use a laser level.

With a laser level, everything is much easier. You put it on a tripod, and then either manually adjust it with a bubble level, or turn on self-leveling, in which it will adjust itself.

Using a laser level, you can perform the same actions, but much faster. You just turn it on, set it up with one button and that's it, the level is ready.

Some laser levels have lasers that shine 360 degrees. That is, you just put it in the center of the room and that's it.

How to adjust it?

There are levels in which the possibility of adjustment is provided. The sensitive element (flask with liquid) in such levels is fixed with a bolt.

If the bolt is loosened, the sensing element can be rotated, thereby adjusting the level. Tuning is usually done in one of two ways. Either we simply move the flask with our hands (such an adjustment is less accurate), or an adjusting bolt is provided, by turning which we adjust the position of the flask (more precise adjustment is possible). Not all hydraulic levels are suitable for adjustment. There are those in which the flask is glued. If such a tool is faulty, it must be thrown away.

Adjusting the level is not a problem if you have a strictly horizontal surface.

But there is a vicious circle. To repair the building level, you need a horizontal surface, and to find a horizontal surface, you need a serviceable level. Get a horizontal surface with a broken spirit level.

We cut a stack of small pieces of paper, for example, newspapers. Find a stable (fixed) approximately horizontal surface. Let's put our faulty level on it.

Let's put a few pieces of paper under one end of the level so that it shows horizontality. Let's remember how much paper was put in this (first) time. Let's flip the level horizontally so that its right end is now on the left, and its left end is on the right. If the level is correct, then it will continue to show horizontality, since a good level shows the horizon, and the horizon is one, from right to left, from left to right. If the level needs to be adjusted, as a result of turning over the air bubble in the flask will shift, the level will show that it is no longer horizontal.

Let's put a few more pieces of paper under one of the ends of the level so that it again begins to show horizontality.

You may have to put paper under the same end as last time, perhaps under a different one. At the same time, we count each enclosed piece. Now we will remove exactly half of the pieces of paper placed in the second stage.

If there were an odd number, then round up. Congratulations, we got the true horizon.

But the level shows a deviation. We release the fixing screw, turn the flask so that it shows horizontality, clamp the fixing screw. Setup completed successfully.

Adjusting the vertical bulb is done in exactly the same way. But you need an assistant to complete it, since it is performed on an approximately vertical wall.

And on such a wall, pieces of paper and the level by themselves will not hold. The assistant will have to hold them.

From a mathematical point of view, the proposed method is not quite accurate, but for construction purposes, the error is acceptable.

Unfortunately, errors occur periodically in articles, they are corrected, articles are supplemented, developed, new ones are being prepared.

High-quality repair in an apartment, cottage or private house is impossible without the level of the building. It is necessary to determine the deviation of the surface plane from the horizontal or vertical length.

Whether you're installing drywall, plaster walls, stretch ceilings, slopes, tile placement, or just hanging cabinets, you'll need a spirit level.

What level should I choose?

How to choose the level of construction? is a frequently asked question about every newcomer or ordinary citizen who decides to fix his own hands himself.

The range of these tools in the modern world is very diverse. Today the market has many different types of levels from simple cheap ones to the most advanced professionals.

But we need an accurate and reliable level. First, let's find out what their differences are and consider each of them.

Water level (water level)

Builders often refer to this as the water level. It is used when it is necessary to detect deviations from horizontal surfaces. Its working principle is based on the properties of water to establish a horizontal position in accordance with the law of communication ships.

The water level is a tube up to 25 m long, at the ends of which there are bulbs with a scale.

The water is poured onto the surface of the water, resulting in a noticeable weight.

Prostate.
Low cost (about 100-200 rubles).
Ability to work with very large surfaces.

When the level is filled with water, it is necessary to control the absence of air bubbles, otherwise the measurement error will be large.
Do not use tools with heaters.
For horizontal surfaces only, it is not possible to work with vertical surfaces.

bubble design level

This is the most common.

It consists of a body in which several small glass flasks are closed with a liquid. Depending on the number of lamps, it can be determined by horizontal accuracy (one bulb), horizontal and vertical (containers), horizontal, vertical and inclined (three bulbs) surfaces.

The most accurate bubble level is, of course, the one with three flasks. Most often, the bubble has a rectangular shape level ranging in size from 200 to 2500 mm.

The choice of length depends on the size and accuracy of application to the surface.

The body of the level is made of lightweight and powerful materials such as aluminum, plastic, wood or polystyrene, and most often alcohol is poured into flasks. Some bubble levels are made with magnetic plates to help process metal items. They are also called magnetic levels. Sometimes the mark refers to one of the two levels of the bubble, for use as a ruler.

How to choose a building level bubble level type?

Of course, it's better to focus on a good brand that makes professional tools.

For example, the level of construction of the German company Stabila (costs about 600-1600 rubles). This company produces magnetic levels, as well as various devices that allow you to work with an electrician (there are special slots for marking a switch or socket).

For full scale measurements of the 600-700mm level, you don't need to buy a two-level level.

In addition to Stabile, you can also choose from Shark tools.

This indicator is not terrible to fall or hit, it will not suffer. From the goods you can still buy: Bosch, Kapro or Ermak.

How to check the level of a building?

You must place the level on a level surface.

For example, it could be a desktop or a sales window. Remember your position, then put the second level in the same place. The bulb bottle of one of them will most likely move aside. If this happens, remember the position of the bubble according to the sections of the lamp.

Rotate the tool 180 degrees and insert it into its original position.

If the air bubble moves to the same position, the level is displayed correctly. If it doesn't, change the level to a different one and try a new one. You can also check any vertical level with water.

Prevalence.
Easy to operate.
Some allow you to measure at an angle.

Pipe level

This type of level is also a bubble, but it has some minor differences.

They have less weight, some may fold. The pipe level is designed to work with pipes and profiles, which are most often equipped with additional devices for fixing pipes.

Availability.
Prevalence.
Simplicity and practicality of work.

There is a small chance of error.

Laser levels

Laser levels are the most accurate of all the presented models.

These modern instruments are very reliable and at the same time very expensive. Their prices range from 2,000 to 18,000 rubles, depending on the manufacturer and many features.

This is a very handy and compact tool with high technical capabilities. The advantage is that the laser beam reaches a length of up to 100 meters. If you are planning to purchase this type of level, it is better to choose reliable brands such as Bosch or GrossLaser.

Easy to operate.
Very high accuracy.
Compactness.

How to set and use the building level?

In order to properly manage the level of a building, it is necessary to properly adjust it.

To do this, read the instructions. This is an individuality for each brand and model, it contains all the necessary rules and recommendations. Some have bike setup settings, others if it's an electronic level it's likely to be auto setup, just the support system will need to be selected.

It is very important to follow the instructions, as even a new level has a certain error. Correctly adjust the level.

To properly adjust the hydraulic level, it is necessary to fill with water and observe the absence of air in thin pipes to the zero mark of the bottles.

After that, the lamp labels should be combined. If it doesn't, there are air bubbles or the tube is transported somewhere. Do not fill the water level with ice or overwhelming water, the liquid must be at room temperature. This facilitates an even distribution of heat over the entire contour of the level, ensuring maximum measurement accuracy.

The level of the bubble requires careful treatment.

building class

This is a very delicate instrument. Do not press it hard, do not look or smear it. It is enough to simply apply it effortlessly to the surface, and if the surface is perfect, the air bubble will obviously be in the middle of the measuring marks.

Try to regularly check the accuracy of the level measurement, as it can be misleading.

Building levels: types, selection and purpose

The level is an indispensable tool when performing construction and installation work. It is necessary for the correct installation of doors, windows, laying bricks and tiles, checking the verticality of the walls, the horizontality of the floors. With its help, the installation of modern household appliances, communications.

The right choice of measuring tool significantly improves the quality of work and saves time.

By design, five main types of building levels can be distinguished: bubble, electronic, pipe, hydraulic, laser. Below we will look at each of them in more detail.

Five types of building levels

bubble levels are most widely used due to their simplicity, accessibility and versatility.

They are called so because the sensitive element they have is an air bubble floating in the ampoule. The measurement error of these devices is 0.5 ÷ 1 mm/m. Domestic models are produced in accordance with GOST 9416-83, which describes the technical conditions for their manufacture. The body of the tool is a hollow box-shaped structure with stiffeners. It can have a length of 30 cm to several meters.

To reduce weight, the device is made of aluminum alloys. Ampoules with air are covered with protective glass. At the base of the case, as a rule, there is a millimeter scale of measurements.

Magnetic bubble levels are perfect for working with metal structures.

Their distinctive feature is the presence of built-in magnets that allow you to fix the tool vertically on metal parts. For masons, there are models with a reinforced cast body.

If you have plastering work ahead, pay attention to the rules with the level. They combine two devices at the same time.

Electronic levels with goniometer belong to professional measuring tool.

They have several bubble chambers to assess the verticality and horizontality of building structures. However, unlike conventional levels, such devices have a number of additional features.

One of the main features is the digital display, which clearly shows the amount of deviation in degrees.

At the same time, the accuracy of the data provided is high - up to 0.1⁰. It is possible to record the measured slopes. Sound indication is provided, which signals the achievement of 0⁰ and 90⁰.

Checking the accuracy of the electronic level is simple and does not take much time. To do this, you need to put the device on a flat surface, take readings.

Rotate the level 180 degrees to see the new values. If the reading difference is more than 0.2⁰, the device needs to be calibrated.

pipe level designed to check the horizontal and verticality of water, gas, sewer pipes.

In general, it is convenient to use it for working with beams, a round profile in various building structures. The main features of this tool are the V-shaped body, the presence of magnets.

Thanks to this, the device can be easily installed on a metal pipe or support.

The pipe level, like the bubble level, is equipped with several flasks with alcohol liquid.

An air bubble floats in each of them, by the location of which the deviation from the given direction is determined.

Hydraulic level used to apply precise horizontal markings on distant objects. With its help, they beat the floor level, install the foundation, lay bricks, install various building structures in one plane.

The hydrostatic level consists of two vessels connected by a transparent tube.

Before operation, the system is filled with water so that it occupies approximately 2/3 of the volume of the flasks. At the same time, make sure that the liquid inside the tube does not contain air bubbles. They must be removed, otherwise the measurements will be inaccurate. Bends and fractures of the tube are not allowed: water must flow freely from one vessel to another.

To check the accuracy of the instrument, the flasks are aligned with each other. It is necessary that they have a common fluid boundary.

The industry produces hydrostatic levels from 5 to 25 m long. The measurement error of these devices is 2÷3 mm. It is recommended to markup from one base mark. This allows for maximum accuracy.

Laser building levels(levels) belong to the group of professional measuring instruments.

Despite the relatively high cost compared to other solutions, they provide their owner with a number of advantages. First of all, it is the high accuracy of markup. The value of the permissible deviation is only 0.1÷1 mm/m, depending on the class of the device. The technical capabilities of linear laser levels allow them to build horizontal, vertical, as well as inclined planes at a distance of up to several tens of meters from the installation site.

For home use, this is more than enough. Rotary laser levels, due to the rotation of the emitter, project beams around the entire perimeter of the room, that is, they cover the entire space around them.

What construction work is carried out with the help of laser levels:

leveling walls or floors;
installation of attachments;
wall papering;
installation of stretch ceilings;
tiling of premises;
installation of partitions, etc.

How to choose a building level

To carry out repairs with high quality, even before starting work, you should choose a good measuring tool.

Now there is a wide variety of building levels. They differ from each other in purpose, technical characteristics, workmanship and price.

What is the task before you?! If you need an inexpensive universal tool for all occasions, you should pay attention to bubble levels.

They are comfortable, unpretentious, and most importantly - have good accuracy. Their capabilities are enough to evenly lay tiles, install windows, doors or furniture. The length of the universal level is 60÷80 cm.

Electronic levels with a goniometer and a magnetic system are suitable for those who decide to take repairs seriously.

They have advanced features. First of all, this is a visual presentation of data on an electronic display with an accurate indication of deviations in degrees, percentages or millimeters. Other distinguishing features are high accuracy, the function of recording readings, as well as the possibility of electronic calibration.

If you need to level beams, poles, water or gas pipes vertically or horizontally, take full advantage of pipe levels.

Their indisputable advantage is the possibility of precise centering on these elements of building structures.

The water level will be useful when installing a floor screed, installing suspended ceilings, and building a foundation. It is useful for marking places for sockets that will look aesthetically pleasing, being at the same height.

How to choose a bubble building level

With a water level, you can make accurate horizontal markings for adjacent rooms, between which there is no direct line of sight. This is one of its main advantages. This tool is low cost and easy to use. Its length varies from 5 to 25 meters, which is quite enough for domestic use.

The laser level will be an excellent choice for those who have a large amount of construction work.

It will significantly save time, while ensuring high accuracy of construction of both horizontal and vertical planes. This is a good tool for beating the floor level, marking the walls for finishing work, installing furniture and communications.

There are three main types of laser levels: point, linear, rotational. In accordance with the name, they are used to build points, lines, and markings around the entire perimeter of the room at the same time.

Before starting work, the lasers must be leveled using the built-in bubble level.

Some models have an additional self-leveling function within 2÷4 degrees. The price of professional laser levels is quite high, but there are affordable options for home use.

What to look for when choosing

Among the large number of manufacturers present on the market of measuring instruments, there are those who have already managed to gain an excellent reputation in our country and abroad.

In good standing with builders, there are bubble, as well as electronic levels Stabila and Kapro. Bosch laser levels are known for their quality. However, it is best to rely on your own experience in order to purchase a thing with the necessary set of functions for a reasonable price.

The main selection criteria: technical characteristics, equipment, build quality and materials.

When purchasing a bubble level, you need to examine its appearance. Is there any visible damage? What is the quality of the materials, is it neatly assembled?! Particular attention should be paid to ampoules with liquid.

They must be securely integrated into the case.

Place the chosen level on a flat horizontal surface. It should fit snugly, without gaps, to it with its base. Note the position of the air bubble in the upper ampoule.

After that, turn the device 180⁰ clockwise or counterclockwise and put it in the same place. If the bubble has moved relative to its initial position, this level cannot be trusted.

Similarly, you can check the vertical accuracy of the readings.

Possible difficulties with the level

For those who are going to make major repairs in the apartment, the question of how to recapture the floor level so that it is ideal will certainly arise.

But for this, you must first determine how large the error is and understand how many materials and elements you need to purchase. Fortunately, the modern market offers many options, thanks to which it is possible to carry out alignment work with high quality and without any problems.

Methods and materials for measuring floor level

Each owner of an apartment or house independently chooses a scheme according to which the surface of the lower part of the room will be transformed.

The question of how to set the floor level is of particular importance in the case of:

If the surface was previously leveled, but excess raw materials remained on it and were not removed;
If mistakes were made during construction and the surface was initially uneven;
If the floor level in a private house is not sufficient for the introduction of a new coating;
If the house or apartment is old and the surface has been damaged due to chemicals or the influence of external factors (flooding, fungi, dampness).

In any of these situations, you can fully determine how to check the floor level to fully transform the premises of an apartment or house.

Based on the photo of the future repair of the space, it is necessary to conclude how much it is necessary to raise the level of the lower surface of the room.

There are various options for how to measure the floor level, the main ones are:

Level measurement using a hydro level (water level);
Measuring the error in the evenness of the surface with a laser (read also: "How to check the evenness of the floor: ways to check in practice");
And also, measurement with a level, this option is used mostly by professionals.

Each of these options is suitable for its implementation.

Hosts can choose the appropriate one based on:

Device pricing policy;
Skills and experience;
The technical side of the issue.

Hydraulic level

This level is a structure consisting of:

rubber tube;
Two containers at both ends of the product.

In working with such a device, it is necessary to act in pairs and step by step. As a rule, this method is most often applicable, both among experienced builders and repairmen, and among beginners.

Step-by-step actions when asked how to display the floor level:

First you need to pour the liquid into a rubber transparent tube, usually pour water. The tube should be filled to the extent that it is planned to raise the floor level;
Then one of the participants in the repair work raises his end of the tube to the required height and, where the water stops, puts a mark on the wall surface;
How to determine the level of the floor will become clear when the second participant in the repair reincarnations brings the tube to the other end of the room.
It is necessary to wait a couple of seconds for the liquid to fully level in the vessel. After that, also put marks at the level where the water stopped in the tube;
The same manipulations can be performed with all other sides of the wall;
After the marks, you can slightly lower the level if it turned out to be too high.
To do this, you need a special meter. In this case, it is necessary to lower the level of the mark on both sides by the same number of centimeters so that the flooring does not turn out to be too high.

Water does not move through the hydraulic level tube. In this case, the instrument should be washed, perhaps there are some stagnant specks, due to which the liquid does not move through the vessel. You can also blow out the hydraulic level so that excess items that interfere with the normal functioning of the device come out of it.
Water not level.
Such a nuisance may appear due to the formation of air bubbles. You can get rid of them by tapping on the hydraulic level tube or by re-filling with water under high pressure.

Laser level (Leveling level)

Difficulties in the question of how to use the laser level to level the floor should not arise.

The process of using this method to determine the height of a surface is very simple.

This equipment kit includes:

Installation emitting laser beams;
Tripod (nozzle);
Stand, thanks to which you can vary the height of the device.

Having understood the scheme of how to check the level of the floor with a laser level, the work process will not take much time at all, and this function can be performed even singly.

Step-by-step instructions on how to beat off the floor level with a laser level:

First of all, you need to install the device. Depending on the cost, and consequently, the quality of the tool, the installation process may be different. In budget models of the product, the equipment will need to be directed to each wall in turn.
The best building levels according to user reviews

In laser leveling systems, the illumination of laser drawings falls on the entire area of the room;
The second step is to draw the line drawn by the laser on the wall.
This function can be carried out using a special upholstery cord or using a ruler and a pencil.
After that, you can begin the process of leveling the surface of the floor covering.

Possible difficulties with the level

Determining the level of the floor with a laser (leveling) installation, it is extremely difficult to make a mistake.

However, errors are possible in the case of:

If the edges of the laser directions are unevenly set;
If, when transferring borders to the surface of the wall, the master or the owner of the apartment of the house incorrectly applied dotted lines;
If the level is set too low or too high.

Conclusion

When choosing any of the options for measuring the level of the floor surface, the result will be accurate.

The only difference between these two measurement devices is the level of difficulty in use:

The laser machine is very easy to use and with it the performance of work is reduced to minimal actions on the part of the worker.
But the cost of this device is quite high, from 5,000 to 20,000 Russian rubles.
The hydraulic level also allows you to clearly determine the height of the surface. This device requires a lot of effort on the part of the participants in the repair. But you can even make this installation yourself, from improvised means, which can always be found in the pantry or in the garage.

Having carefully studied all the details and nuances of using floor surface level meters, you can fully and ideally carry out the process of leveling the lower part of the room.

When building a house, overhauling or redecorating, assembling and installing furniture, one of the necessary tools is a building level. It is he who allows you to clearly determine the deviation from the vertical or horizontal line. The building products market is replenished annually with a variety of models that differ in technical characteristics and the principle of operation. Having studied the rating of the best samples, everyone will be able to accurately determine the most suitable option for themselves.

Notable building level companies

Among the variety of offers from different companies, home craftsmen and experienced builders have identified several brands that specialize in the production of building level. Their products have earned confidence due to the high build quality and the ability to determine the exact parameters.

The company was founded back in 1889 and from the very beginning produced building measuring devices. He has many patents and is considered one of the leaders in this field. The key advantage of the meters is the start immediately when the rulers are extended, the overall ergonomics and the price. The downside concerns electronic meters - many complain about weak batteries. And if this is not important for a house, then at a construction site or other large facility this is a serious problem.
