How to choose the right building level? English language proficiency levels. Determination of the level of English How long the level to choose

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.



It is intended for check of horizontality 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.



It is used for applying accurate horizontal markings on objects that are far from each other. 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.

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. 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 measuring instrument market, there are those who have already gained 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.

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 the technical characteristics and indications of the device are often violated during transportation.

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.

Without a spirit level, or building level, it is difficult to imagine the quality of many construction, finishing and repair work. Its working purpose is to accurately determine the possible deviation of any surface from the vertical or horizontal. Using it, you can create perfectly straight lines on a plane, measure the desired angles and inclinations.

Levels are absolutely indispensable for the arrangement of surfaces that have special requirements for the angle of inclination. You can’t do without them when installing equipment that vibrates during operation, which needs a perfectly parallel to the floor location of the installation surface. This device is necessarily present in the arsenal of tools of both professional craftsmen and amateurs. Therefore, it is important to be able to correctly choose the building level.

For professionals, special shockproof models are very relevant. During transportation, or while working at a construction site, devices are often subjected to shocks, vibrations, falls, from which they often break. Oversized models are especially affected: the impact force that occurs when they fall will be greater, due to their size. The price of an anti-shock device will be slightly higher, but it's worth it. It is better to spend money on a reliable device once than to endlessly replace failed ones.

The base of the device is usually made of wood, aluminum or modern plastic. Wooden elements are made solid, bases made of other materials are hollow inside. Products with an aluminum component are more common. Not the last role in the choice of the device is played by its mass, because the heavier it is, the more reliable its readings. Professionals consider the best devices to be those that are cross-shaped and equipped with rubber grips: they are more accurate and comfortable.

Special magnetic levels designed to work with metal surfaces. An addition that is quite necessary for work is a ruler located on the long side of the tool. It turns out to be very useful when carrying out various measurements, and is quite capable of replacing a tape measure. The simplest representative of these devices is equipped with only one measuring ampoule. Such modifications are extremely rare on the shelves.

Most often, manufacturers offer devices with two or even three working ampoules. On the wide long side there is one ampoule, which serves to determine the quality of horizontal planes. On the short narrow side, which is at right angles to the main one, there is a second container for working in the vertical.

On the reverse side of the narrow part, a third ampoule can be located, which should control the correct operation of the device itself. The industry offers devices not only of various modifications, but also of different dimensions.

The small standard model is 20 cm long and about 4 cm wide. The dimensions of the level determine its narrower purpose. For the correct installation of household appliances, and for the implementation of minor repairs in the premises of a residential building or apartment, a small device is enough. To work with finishing materials, when laying tiles, devices from 40 to 100 cm are more convenient. Professional, the most dimensional of their bubble levels, are needed for large-scale construction events. It is believed that the length of the building level correlates with its accuracy: the longer it is, the more reliable the readings of the device.

How to choose a building level?

Building levels have always enjoyed a certain demand from buyers. After all, these devices are used not only by professionals, but also by ordinary citizens who may need the product for simple repairs. The industrial production of levels is not an extremely difficult task, but it requires quality materials, accurate calculation and careful processing. These components guarantee the high performance of the instruments, ensuring the accuracy of the readings.

The following brands supply high quality products:

• Stabila
• Bosch
• Shark (Israel)
• Kapro
• Ermak
• Gross Laser
• Leader.

Even knowing the leading manufacturers, in order to make the right choice, you need to know certain important features.

After all, many buyers do not at all dream of buying a product of a famous brand at an incredible price: people do not want to overpay for an item that is occasionally required in the household.

1. First, we determine the size of the desired device. They depend on its purpose, on the tasks and goals set for it. If you have to level the surface, carry out finishing work, then you need a sufficiently large device. If minor repairs are to be done, such as installing sockets and switches, installing hanging shelves, attaching paintings, installing individual pieces of furniture, then a medium-sized level will suffice. The most suitable tool for household and household needs is about 60 cm long.
2. In the store, you should look at all the details of the device made of glass. They must be intact, not damaged, without traces of extraneous influence. It is necessary to check the reliability of their fastening, all elements must be tightly fixed, and not hang out to the sides. On sale, you can find options for devices with the function of adjusting capacities, but its expediency is rather doubtful. It would seem that the possibility of adjustment allows you to correct the lost level of the device? But at the same time, the device becomes more sensitive to mechanical stress and shaking. Professionals recommend a tool with rigidly fixed parts.
3. Not only the flask is subject to careful inspection. Pay attention to the calibration applied to it, and to the air bubble inside. Everything should be clearly visible and be located at a certain, strictly verified distance from each other. Very convenient is the variant of the product, in which the control strips are located inside, being thus protected from mechanical influences. With such an arrangement, you can be sure that they will not be erased.
4. Another important factor is what the base of the building level is made of. Whatever material is used to make it, it must be strong and heavy enough. Good options for devices that have special stiffeners inside. Each manufacturer chooses their own, individual design for their products. But it should not in any way affect the reliability of the readings of the device.
5. When the external study of the device is completed, you can proceed to its verification. Profile construction stores should be equipped with special stands with a flat surface to check the products sold. If there is none, the check can be carried out as follows. The instrument is placed horizontally and the position of the air bubble is noted. It's okay if he moved from the center position. Then the device is turned 180 degrees in the same place. If the air has not changed its position, then the tool is adjusted and working correctly.
6. Without the presence of a verified surface, with known indicators, it will not be possible to determine the accuracy of the instrument readings. However, you can check them later by comparing them with data from other devices. You can use a laser level or level, the performance of which has already been tested. Do not neglect the check, even when it comes to expensive branded products: the technical characteristics that determine the operational properties may well be violated during the transportation of goods.

When wondering how to choose a building level, any person is aware of the consequences of a wrong decision.

A common type of bubble level is its rectangular modification, which is inexpensive.

After all, any, even the smallest deviation from a flat surface can lead to the most deplorable consequences, up to a complete rework of a just completed repair. Therefore, the question of how to choose a building level should be taken with all care, because this tool can be of several different types, the properties, purpose and price of which can vary significantly.

Currently, the market has a fairly wide range of these construction tools. One of the most common measuring instruments of this type is the bubble level. It consists of a body and a flask filled with a liquid in which an air bubble floats. This level is very simple and at the same time quite accurate and reliable.

What are the types of levels

The principle of operation of the water level.

Bubble levels. The most common type of this level is its rectangular modification. Its length varies widely and can be 2.5 meters. The minimum size is 20 cm. However, occasionally you can find devices of a telescopic design, the length of which reaches 4 meters. Their flasks are made of impact-resistant transparent material. Alcohol is used as a filler.

Some of these tools are equipped with magnets, which makes them much easier to use on steel surfaces. There is also a variety of levels that are used when working with pipes: such tools are usually small in size and have a semicircular recess running along the body. Thanks to it, the device is well kept on the surface of the pipe. These tools have a low price, but versatility is not their strong point, so it is better to choose a different type of level.

water levels. This type of measuring instrument, otherwise known as a hydraulic level, is well suited for measuring the deviations of large horizontal surfaces. It consists of two containers filled with liquid, which are connected by a hose. The main feature of these levels is that their length ranges from 5 to 25 meters, which makes them indispensable when working with extended surfaces and at the same time absolutely useless for use in an apartment.

The principle of operation of the laser level.

They are sensitive to heat, so keep them away from heat sources. You also need to ensure that no air bubbles enter the water when filling the containers, as this significantly affects the readings of this measuring device.

laser levels. Measuring devices of this type are among the most accurate and at the same time the most expensive. Their main advantages are small size and large range, which can reach several tens of meters. They are also best suited for measuring large and extended surfaces, since the laser beam emitted by this instrument can be turned into a plane. In addition, they show themselves perfectly when laying directions. For ease of use, such measuring instruments are equipped with tripods and magnetic suction cups.

Top tools have not one laser beam, but several. They can intersect with each other, facilitating and refining measurements.

This device can definitely be called the best among all levels. It is versatile, accurate, compact and practical. It has only one drawback: its high price.

Choosing a level in the store: what to look for

The type of measuring device largely depends on how large-scale tasks will be solved with it. After all, it is one thing when the level is chosen for frequent use in large-scale construction work, and quite another when it is needed only to level the floor in the apartment.

There is no need to fall under the influence of products of well-known brands and choose the most famous brand, because the main thing in any thing is its quality, and this indicator often has nothing to do with a big name.

How to choose a bubble type building level

Diagram of a bubble level.

First of all, you need to decide for which tasks you need this measuring tool. If you are going to level the walls with it, then you need to choose the maximum length level, but if the question is posed much more modestly and you just need to attach a bookshelf, then the tool, accordingly, should also be smaller.

The air bubble itself should be clearly visible, and the marks on the level flask should be black and there should be several of them. These marks should be very close to each other, forming a kind of scale.

After this verification step, you can proceed to the next one and test the accuracy of the instrument. If the purchase is made in a specialized store, then for sure he has special stands that are specifically designed to test such measuring instruments.

For the test, the device should be placed horizontally and accurately remember the location of the air bubble on the flask scale, then turn the level 180 degrees. If everything is in order with the device, then the bubble will not change its position relative to the scale.

After that, you need to check its work in a vertical plane. For this, an appropriate stand is selected, to which the device is applied. Further, everything happens, as in the previous case: the location of the bubble is remembered, then a 180-degree turn follows. If the bubble remains in its place in this case, it means that the level is made with high quality and you can safely buy it.

In the absence of such a stand in the store, upon arrival home, you need to invite a person who has a level or laser level and use these tools to check the correct operation of the purchased one. If something does not suit you, then there is always the opportunity to return the purchased device back to the store.

What to look for when buying a laser level?

If you have made a choice in favor of a laser measuring device, then when buying, first of all, you should pay attention to its technical characteristics, the main of which are measurement error and range. The accuracy of the laser level must be at least 3 mm for every 10 meters, and the range must be at least 20 meters.

Often, this device comes with special glasses that allow you to better see the laser beam.

In addition, these devices are equipped with two types of lasers, which differ in the color of the beam they emit. Red emitters are the most common, but if possible, it is better to choose an instrument with a green beam, since this color is more visible and contrasting to the human eye. However, levels with a green laser are somewhat more expensive than their "red" counterparts.

It is worth taking a closer look at what is included in the package of the device.

Often it is very diverse and includes both many useful items and those that you can do without.

If, along with the purchase of a laser level, you are going to purchase some kind of addition to it, then be sure to consult with sellers or friends who understand such things in this regard, so that it does not happen that the purchased accessory does not fit your type of device.

Buying a level is a very important step, on which the quality of the upcoming repair directly depends.

How to choose a building level? And which one is better?

The final result of the work of a number of industrial specialists depends on the accuracy of measuring instruments: a builder, a bricklayer, a carpenter, etc. The building level of various modifications is a simple but indispensable tool for any serious team or individual craftsman, which allows you to determine the accuracy of the location of horizontal and vertical surfaces. The history of the appearance of the first spirit level dates back to the second half of the 17th century, and the vertical plumb line is the well-known primitive prototype of later inventions.

The generally accepted classification for building levels:

• Bubble (water level) - with flasks installed in a rigid case filled with liquid, and the presence of a floating air bubble in each flask;
• Laser level - with fast and clear marking by a point of a laser beam of working surfaces;
• Water level (hydrolevel) - the principle of operation is based on Pascal's hydrostatic law and checks the compliance of the planes of horizontal surfaces.

Despite all the obvious innovative advantages of the same laser level, skilled craftsmen never refuse to use a high-quality bubble level - this versatile tool that has stood the test of time.

The main characteristics of the building level

• Measurement accuracy (from 0.3 mm / m, the longer the building level and the heavier it is, the higher the accuracy of its readings);
• Impact resistance. As a rule, levels have a hollow body, but with walls of sufficient thickness;
• Wide resistance to the slightest bending and torsion;
• Measuring flasks with a high degree of transparency and resistance to discoloration, haze, cracking and leakage when exposed to low and high temperatures, as well as ultraviolet rays.

Device

A rigid monolithic, most often rectangular case with a milled bottom edge is made of light and durable materials (aluminum, polystyrene, plastic, wood) with an anti-corrosion coating. In the case, depending on the required accuracy, a certain number of transparent sealed glass flasks (level eyes) are securely fixed with an air bubble floating in a colored alcohol-containing liquid:

• one flask - only for a horizontal guide (180 degrees);
• two - for horizontal (180 degrees) and vertical guides (90 degrees);
• three - for more complex work, with an additional third camera that controls the measurement of the angle of inclination (rigidly fixed at 45 degrees, or swivel - to measure any angle of the controlled surface).

In order to minimize errors in angular vision, limiting lines - risks - are applied on the surface of the measuring flasks. Eyes for checking the position of surfaces of the vertical plane and the angle of inclination have built-in mirror reflectors for simultaneous control of the position of the bubbles.

Plastic plugs at the ends of the level protect the structure in case of accidental drops.

Some level manufacturers also provide additional conveniences: for example, a built-in magnifying lens for more comfortable bubble control, magnetic systems or a fluorescent flask liquid for the possibility of continuing work even in the dark.

The principle of operation of the bubble building level is simple: measuring and adjusting surfaces relative to the horizontal and vertical planes occurs by moving the bubble inside a certain level eye. The result of the correct adjustment will be the presence of the bubble exactly in the middle between the measuring marks of the flask.

Building level. Which is better?

Having decided to purchase a building level, it will not be superfluous to familiarize yourself with some recommendations for choosing it:

1. Flask - must be securely fastened in the body. When buying, it is worth abandoning the level at which the flask is screwed with screws, because of which it can become loose over time. Flasks made of polyacrylic should be chosen, which is stronger than glass and more transparent than plastic.
2. Level length - it is necessary to take into account the type of work to be done, since the larger the working area, the longer the level should be chosen;
3. Defects - the building level is a measuring device, so when buying a tool, you must make sure that there are no factory defects, as well as errors in the readings.

1. Case material - the tool can be made of plastic, metal or wood. The most reliable and durable is, of course, the metal level, inside which there are stiffeners
2. Markup - the best option is to place control strips inside the bubble itself. The divisions applied to the surface of the flask should be clear and located close to each other.

The run-up in the cost of building levels is quite diverse. At the same time, it is not worth asking for a choice of more economic models, especially if you need to use the tool repeatedly. If you have to carry out a thorough repair, then experts strongly recommend purchasing a professional tool. For him, a characteristic difference is the presence of a shock-resistant case with special rubber pads, which, during operation, are able to soften the blows from falls, etc.

In operation, it is better than others, the construction level of the famous German brand "Stabila" has proven itself. For such a tool, on average, you will have to pay from 700 to 1800 rubles. This measuring device is famous for such advantages as:

• high-quality and stable reading of indications (high degree of measurement accuracy);
• good ergonomic characteristics;
• precision in the geometry of the aluminum profile housing.

In addition, this brand also produces magnetic building levels, which make it possible to work with electricity, and are equipped with special slots for marking switches and sockets.

In addition to "Stabila", another good option could be the building level of the company "Shark". The levels of this brand are good because they are not afraid of falls and bumps. Also, good models are produced by Ermak, Bosch or Kapro. For example, the Kapro company constantly updates its models and often introduces the latest innovative solutions, releasing household and professional tools. The models of the German company Bosch are distinguished by high quality. A similar tool with Bosch models is also produced by the Russian company Condtrol, which is more affordable.

In the middle category of such instruments, it is worth highlighting the levels produced by Matrix, Brigadier and Stayer, which are distinguished by their high measurement accuracy and optimal cost-to-quality ratio.

However, when buying a building level, a well-known brand should not be a decisive aspect. The main thing is to decide on the type of future work and the frequency of using the tool.

180 degree method

You can check the accuracy of the level in the simplest way, called the 180 degree method:

1. It is necessary to put the building level tightly, without gaps, on a flat horizontal surface and remember the position of the bubble relative to the marks.
2. In the horizontal plane, turn the level 180 degrees and place it clearly on the same area.
3. In a qualitative and accurate level, the position of the bubble should remain the same.

In the same way, you can check the accuracy of the vertical readings.

Round bubble level

This kind of building levels is designed to control only horizontal surfaces and differs somewhat from the usual levels in the design of the body with the same principle of operation. The round level is a sealed hemispherical capsule made of impact-resistant glass with a fixed flask, inside which the position of the bubble is determined by a bounding round line.

The scope of the round bubble level is not only construction work and control of the degree of shrinkage of already rebuilt buildings. Such levels are widely used in photo and video shooting for strict adjustment of the horizontal position of the equipment tripod. The use of round levels is also very common when installing trade or control scales, as well as for constantly monitoring the stable horizontal position of stationary machines, industrial tools and even jewelry surfaces - for example, polishing wheels.

A round bubble level often has the possibility of local attachment to a controlled surface and a very low cost with high measurement accuracy. A knowledgeable person will appreciate this simple and necessary tool.

The ubiquity of levels

Whatever work you have to do (check the correspondence of the vertical and horizontal surfaces of the walls, floor and ceiling; install a washing machine without distortions, hang a bookshelf or a picture) - the simplicity and ease of use of the bubble building level will help you do it quickly and with the highest quality. Even in the presence of a laser level or a plane builder that is more complex in execution and principle of operation, the building level, unchanged in the arsenal of any master, will not remain idle.
