How to know if the gas meter is working properly? How to check a gas meter without removing it, taking into account the service life The procedure for carrying out control measures

Recently, in large cities and metropolitan areas, they have increasingly begun to change to new gas and electric meters. If earlier they could only be found on common house pipes, today they are installed en masse in every apartment. Due to the fact that gas prices are constantly rising, people are trying to find any possible ways to save, just not to pay according to generally accepted tariffs, but to report on actually consumed cubic meters. But more and more often there are questions on the network regarding the fact that a brand new gas meter turns quickly and how you can deceive it or rewind the wound cubes at home. What to do in such a situation, where to turn and what measures to take. we will find out in the next article. And these situations really require attention, because it even happens that the meters wind up twice as much as people used before they were installed.

What to do if the gas meter breaks down, how to get around this problem?

If you find that the meter is winding too fast or, on the contrary, the consumable cubes are not counted, that is, the numbers do not move at all, then you must immediately contact the emergency gas service. So, what to do if the gas meter winds a lot or stops working?

The algorithm of actions is as follows:

1. If there is no leak, that is, there is no smell of gas, but the meter does not work, then you can safely use it, because you yourself have no right to turn it off, but you can satisfy your needs.
2. When waiting for a representative of the city gas service, in no case do not go to the meter on your own, so as not to violate the integrity of the seals, otherwise you cannot avoid penalties.
3. Upon the arrival of specialists, do not take your eyes off them, carefully monitor their every action so that they themselves do not accidentally damage the seal, and then turn all responsibility on you. By the way, such situations are quite common, and the masters begin to extort money from the tenants in order to voluntarily settle this issue.
4. The team must attest to the safety of the seals.
5. After a detailed inspection, your meter can be dismantled and taken away for the purpose of examination and repair, and if it cannot be repaired, then the specialist is obliged to issue you a document to replace it.

The financial side of this issue depends on who has your counter on the balance sheet. During the absence of the device, the monthly fee is charged according to the conditions specified in the contract - more often, average gas consumption indicators are taken.

Important! If a leak is detected, turn off the gas immediately and in no case use the stove.

How to independently check that the counter is winding too much?

To check if your own gas appliance is deceiving you, you need to perform a few very simple steps, namely:

1. First you need to check if it winds when absolutely all gas appliances in the house or apartment are turned off. If yes, then most likely there is a leak or illegal connection to your device.
2. Turn on the device for fifteen minutes at full power and compare the gas flow indicated in the passport of your device and the changes taking place.
3. If the meter has an electronic display and the readings are read even when the gas valve is closed, then it is possible to assert with great probability the presence of so-called stray currents, the nature of which is not always possible to determine.

Important! More often they occur due to improper connection of stoves with electric ignition in neighboring apartments or when special gas outlets are used.

The most common causes of breakdown of gas meters

Only a specialist is able to determine exactly why the gas meter winds a lot. What should the residents of the house do in this case? Of course, less amateur performance, because in such situations it does not lead to anything good. These devices are too complicated in terms of device and features of operation to figure them out on their own.

The causes of excessive gas consumption are usually the following factors:

1. Most often, the reason for the failure of the meter is a problem that has arisen in gas equipment and the characteristics of natural gas consumption. For example, if you use 10-20 cubic meters of gas per month, while using a gas boiler with only one wick, then you need to reconsider the effectiveness of such a huge consumption, because this is a pretty decent figure. In such a situation, it is necessary, first of all, to evaluate how efficiently your house retains heat. You may have to insulate it, and then gas consumption is guaranteed to noticeably decrease.
2. Banal leak. By the way, when it occurs, you may not smell the gas. But you can safely diagnose a malfunction yourself. You just need to coat the gas valve and all connections with a foam solution made from ordinary shampoo or soap. If bubbles form, it means that a leak is absolutely taking place and an urgent need to call a specialist.

In this article, we examined all the reasons why the gas meter turns quickly or does not turn at all, and compiled step-by-step instructions for you on what to do in such situations. We hope you managed to solve the problem competently and quickly.

Dear metrologists, please answer if there are any methods for checking gas meters at home. 12/6/2013 came from Gorgaz with a check on the counter. I have LIS1-02 from the Tula plant "SPLAV". The next verification deadline is 09.2019. They forced the boiler to be extinguished and the smallest burner of the gas stove to be turned on, and according to the product passport, they began to check the counter indication with a stopwatch - in standby mode after 12 seconds, indication for 2 seconds - in operating mode according to the passport after 6 seconds - but after 6 seconds the indication did not light up, it turned on after 12. They wrote an act that the meter consumes, but does not count gas. Now he counts 20 m3 per day (in Blgorod now -10C), the meter costs 2 years, they came for the first time with a check. Now they say that they will transfer the payment + 3 tenants to the area of ​​​​the house, it will be more than 5.5 thousand rubles. I am a pensioner and my pension is not big. I called the factory in Tula. They answered that checking with a stopwatch is a filkin's diploma. Are there any devices and methods for checking the LIS1-02 meter at home?

Thanks in advance.

Sincerely, Ivan-51

P.S. The counter is set along the axes - 0.1 degrees - 0.2 degrees; according to the passport - 1 degree

Quote highlighted

Firstly, on what basis did they decide to carry out an extraordinary verification of your meter? There must be a document. Secondly, what they did was not verification, but I don’t know what to call such a procedure at all. And even for such a procedure there should be a type of technique. Basically bullshit. Go to court if verbal arguments do not reach them. And why did they come from Gorgaz (the operating organization), and not from Mezhregiongaz of your subject (Belgorod region, as I understand it)?

There are just grounds for verification - Decree No. 549, which has already been mentioned here, and even more verification is the responsibility of the Supplier defined in clause 22 of the Decree. Representatives of "Gorgaz" most likely work under an agency agreement with the Supplier, according to which they have all the rights to check the technical condition of equipment and metering devices. Well, the fact that a malfunction of the device can be detected during the check is stipulated in clause 28 of the Resolution, i.e. and there is no crime here. The methodology to which you refer does not really exist at the legislative level, but it is possibly approved at the level of the Company and its implementation is one of the official duties of an employee of the Supplier or a specialized organization.

I offer you a relatively peaceful way to resolve the conflict situation with the Supplier - contact the specialized organization (Gorgaz) yourself in writing with a request to remove the meter for verification and take it to the CSM. And write a letter to the Supplier that in order to actually establish the serviceability or malfunction of your metering device, you are handing over this device to the CSM for an extraordinary verification. In case of a positive result, your expenses for extraordinary verification should be requested from the Supplier to be reimbursed. But there is also the other side of the coin: if the Gorgas controllers were not mistaken in their calculations and verification at the CSM shows that it is not suitable, then the costs of installing / dismantling the meter and its extraordinary verification, the standard for gas for the period of absence of the meter, the cost re-sealing the meter, and even the purchase of a new meter will fall on your shoulders. Would it be cheaper to just buy a new one?

Over the past few decades, in all large cities, old gas and electric meters have been replaced with new ones. Previously, they were used only on common house pipes, and residents had to pay a fixed amount for the square of their home. Now it has become much easier to save gas, as meters have been installed directly in apartments. Most consumers regularly keep records of consumed resources. Some try to use any methods in order to save gas. Often, residents of apartment buildings and private houses are faced with the problem that the gas meter turns quickly. From our article you will learn what to do, where to go and what measures to take in such a situation.

1.1 Algorithm of actions

• First of all, you need to check the system for leaks. If there is no corresponding smell in the room where the meter is installed, you can continue to use it. You do not have the right to take any measures on your own, as they can be dangerous.
• While waiting for the arrival of the master, you should not try to fix the situation yourself. Gas is a combustible and flammable substance, which is why interference in the system by an inhabitant can lead to negative consequences. You can also break the seals, which will cause you to pay fines and send the device for verification.
• When specialists come to you, their actions also need to be kept under constant control. They can accidentally damage the seal, and shift the blame for everything that happened to you. Such situations are quite common. Many users of urban gas communications have repeatedly complained that unscrupulous workers may even demand money for applying a new seal without completing the relevant documents.
• Upon arrival, the safety of the seals must be immediately certified by specialists.

After on-site diagnostics, emergency gas service workers can dismantle the device for examination. In the event of a malfunction, the specialist is obliged to give you a document on the need to replace the meter.

The cost of services for the replacement and repair of meters directly depends on the company that serves you.

You will most likely be charged for the average gas consumption while the appliance is not on site. More detailed information about this should be provided to you by a specialist.

If you find a leak, immediately turn off the gas at the entrance to the house or apartment. Also, you can not use the stove and other devices of this type, connected after the meter.

2 Checking the meter for accuracy

To check the correctness of the readings of the gas meter "in both directions", there is a method in which you need to perform a number of simple steps:

• Check how your meter works when all appliances in the house are turned off. If the device continues to wind, then there is a leak on the line, or someone has illegally connected to your system.
• For about 15 minutes, turn on any device at full power. The indicators from the meter must match those indicated in the passport to it.

When working with meters with an electric display, there is often a problem with indicators. Due to the so-called "stray currents", the device counts the used cubic meters of gas even if all the appliances in the house are turned off. To solve this problem, you need the help of qualified specialists.

Most often, such meters fail if there is a stove with electric ignition in the apartment or house.

3 Common Causes of Gas Meter Failures

Only a specialist can determine the type of breakdown and the method of solving the problem. The question of why the gas meter shows a lot can be answered in different ways. Most likely, you will not be able to solve the problem on your own, but it is worth considering the most common causes of instrument failures:

• The most common cause of failure of a gas meter is a malfunction of gas equipment. In particular, you can use approximately 20 cubic meters of fuel with only one wick boiler. These indicators mean that your device is faulty or has errors. First of all, you need to evaluate how well your home is insulated. After installing high-quality double-glazed windows and applying an insulating coating, the situation with gas consumption may change for the better.
• The second reason that the meter winds quickly may be a leak. The line must be checked after the device itself, since in case of problems outside your house or apartment, changes in the readings would not concern you. A soapy water solution must be applied to the entire length of the pipe and connection. If bubbles appear in any of the areas, then there may be a leak. If it is detected, contact a specialist immediately.

4 Subtleties of repair and replacement of the meter

• The rate at which you will have to pay during the absence of the meter is calculated for each family member. Most often, service companies apply tariffs that are used for houses and apartments without metering devices.
• If you still have to buy a new meter, then it will have to be re-registered. In this case, it is difficult to determine the cost of all services, since it depends on the service company.
• Do not delay in contacting specialists, as they may not arrive immediately. First of all, close the pipe at the inlet and turn off all gas appliances in the house.

5 Expert opinion

“The most common reason for winding up extra cubes is a leak. It is worth checking the system for it even in the absence of a characteristic smell. You can use soap or shampoo for this., - writes Internet user Anna.

pay at the average rate is very expensive? Galina, Volgograd region The question is not so much legal as technical. If you have any doubts about the correctness of the meter readings, you should write about it to the gas service, referring to clause 14.12 of the Rules for technical operation and labor safety requirements in the gas industry of the Russian Federation (approved by order of Rosstroygazifikatsiya dated October 20, 1991 No. 70-P, with as amended on March 22, 1994). You do not have the right to remove the counter yourself. This should be done only by employees of the gas service. But how the meter will be replaced if it is not Araven, you will decide by agreement with the gas service. One more thing I can add: a meter showing a higher gas consumption when heating water in the cold season is considered normal, since more energy is required to heat colder water, in this case, burnt gas.

Although gasometers appeared in homes many years ago, not everyone knows the details of their maintenance. In order for the owners and the gas supplying service to have confidence in the accuracy of the measurements, the device must be periodically tested. You can carry out verification without dismantling the device. But you need to know how to do it. Do you agree?

You will find detailed information on how to check a gas meter without removing it in our article. We have described in detail the types of flowmeters, their principle of operation and given the frequency of maintenance. We have detailed the sequence of actions required for verification without dismantling.

Gas controllers are convenient devices that allow you to monitor the consumption of natural gas.

There are many models of such devices, which, according to the principle of operation, can be divided into categories:

• membrane;
• rotary (rotary);
• turbine;
• vortex.

Let's consider each type in more detail.

View # 1 - membrane devices

Such devices (also called chamber or diaphragm) have a low throughput (about 12 m 3 / h). The work is based on the principle of dividing the gas flow with the help of membrane components into volume fractions with their subsequent summation.

Controllers of this type are most often used in everyday life. They are easy to operate, have good measurement accuracy, and are resistant to magnetic fields. Membrane gas meters are also affordable due to the fact that their internal parts and assemblies are made of plastic.

Membrane models of counters are widely used in everyday life. Such devices are installed not only inside residential premises, but also in private houses or in porches.

At the same time, such devices are quite durable: their covers are made of cast aluminum or stamped steel coated with an anti-corrosion compound, and the polymers from which the mechanism is made are resistant to aggressive substances contained in natural gas.

View #2 - rotary devices

Although such devices are small in size, they are distinguished by a large throughput (10-1000m³ / h) and a wide measurement range.

The principle of operation of rotary controllers is similar to chamber controllers, but the converting element is made in the form of an eight-shaped rotor, which rotates under the influence of a gas pressure difference. To reduce the friction that wears out the active part, constant lubrication with oil is required.

Rotary or rotary gas meters are designed to measure the flow of non-aggressive gas mixtures and natural gas on a commercial and industrial scale

This type of gas meters is characterized by such qualities as durability, the ability to control the readings of the pressure drop in the meters. Due to this, such devices are widely used in housing and communal services, especially in heating boilers. Small rotary devices can also be used in houses and apartments.

View # 3 - turbine options

The operating element of such gas meters is a turbine wheel, which rotates under the influence of a gas flow, while the number of revolutions directly depends on the volume of the flowing flow of volatile fuel.

The counting mechanism installed in the device counts the number of rotations, showing the volume of the substance that passed through the counter during its operation.

Turbine models are produced for measuring flow in high pressure pipelines. They are equipped with electronic devices for easy data reading and regular monitoring.

There are various models of turbine gas meters, which differ both in size and in the level of automation used to take measurements and process results. However, due to the ability of such devices to withstand large volumes of gas flow, it is most advisable to use them at large industrial enterprises with fuel consumption up to 10,000 m³/h.

View #4 - vortex devices

The operation of vortex gas meters, designed to process 50-12000 m³/h of blue fuel, is based on the dependence of the purity of pressure fluctuations on gas flow. Such devices are most often used in large enterprises.

The advantages of this category of devices include:

• lack of rapidly wearing moving parts;
• the ability to work in a significant range of measurements;
• correct functioning even in difficult conditions, regardless of pressure drops in the pipe and temperature effects.

The disadvantages of vortex devices include the impossibility of working with gas flows moving at low speed; the complexity of measuring gas flow in contaminated aggressive environments; the need for electricity.

Vortex gas flow meters are also available for process control and volumetric consumption measurement in industrial and commercial organizations.

The following article will introduce the criteria and guidelines in detail.

The period of use of measuring instruments

In practice, devices usually fail much earlier.

Among the reasons that cause a decrease in the period of actual use compared to the planned one, we can name:

• excessive moisture content in the gas;
• reduced throughput of the device;
• absence of a dust filter or insufficient size of its cells;
• violations committed during the installation of the device.

In order not to miss the breakdown of the gasometer, periodically check the condition of the device and replace it if unusable. Since only licensed specialists have the right to engage in such manipulations, for this you should contact specialized firms.

The Purpose of Performing a Gasometer Test

A mandatory procedure for all users of gas meters is a check, the purpose of which is to identify the compliance of the device with metrological requirements. Article 13, clause 1 "On Ensuring the Uniformity of Measurements" of the Federal Legislation informs that the gasometer must undergo primary control before the start of operation of the device or immediately after its repair.

If the owner of the meter evades from conducting periodic verification or detecting a malfunction of the meter, he will have to pay for gas at higher rates

According to the regulations, during the operation of the device, it is also necessary to carry out regular verification of the device. The "Rules for the supply of gas for domestic needs" (clause 21) states that citizens are required to present meters for control within the prescribed time frame, while they are charged with the costs of delivery.

The procedure for conducting control measures

Evaluation of the performance of the device is carried out in accordance with regulatory documents.

Any check of the meter may only be carried out by qualified personnel. These include employees of the city gas service or licensed firms

The Decree of the Government of the Russian Federation No. 549 dated July 21, 2008 defines the terms and procedure for diagnosis:

1. Carrying out control measures must be coordinated with the owner of the apartment without fail. To do this, the specialists who are responsible for the examination must report it no later than a week before the planned date of diagnosis, and they must receive confirmation of the delivery of the information letter.
2. The inspection can only be carried out by employees/representatives of a specialized company that has entered into an agreement with the tenants for the maintenance of in-house/in-house natural gas equipment.
3. Specialists who diagnose a gas meter are required to present service documents to the owner of the apartment, and, upon request, an identity passport.

All results of control measures are recorded in the act of checking the gasometer.

This document should include the following information:

• date and place of the diagnosis;
• information (full name, passport data) about the owner of the checked gas controller;
• information about the persons who were present at the check, including their passport data;
• indications of the device at the time of the start of diagnostics;
• description of the technical condition of the seals on the device and at the place of its connection to the gas pipeline;
• information on violations, which indicates the specific clause of the agreement under which the defect was made, or a record of the absence of malfunctions.

In the event that at least one of the above rules has been violated, the meter check may be declared illegal.

Ability to recalculate gas fees

The verification procedure for gas controllers is essential. Recently, such devices have become widespread, since they not only help reduce the consumption of a non-renewable natural resource, but also reduce gas payments.

At the same time, the effective consumption of the fuel resource is possible only with the full operation of the meters, which cannot be achieved without an established system for checking them. In addition to the initial assessment of the condition of the device, users are prescribed to carry out scheduled and urgent checks.

Proper operation of gas meters provides the following benefits:

• Substantial money savings.
• Development of consumer discipline when using gas.
• Establishing a scheme for the rational use of blue fuel in everyday life with careful control of its costs.

Thus, the controllers make it possible to economically use the reserves of natural fuel, and also serve as an incentive to maintain the intra-house / intra-apartment gas communications in good condition.

The use of meters is associated with the observance of certain rules, one of which is the exact observance of the prescribed terms for diagnosing gas meters and regular checks of equipment

According to the regulations, the installation of equipment must be carried out by specialized specialists. Such a procedure, which takes a minimum of time, is convenient, safe and comfortable.

Extraordinary check of gas meters

In addition to scheduled inspections of the condition of the device, there are a number of reasons why an extraordinary (urgent) procedure for assessing the condition of the gas meter may be required.

Representatives of gas services can send the meter for verification ahead of time if they suspect the transmission of incorrect data or for falsification

Such situations include:

1. Violation of the integrity of the seal or verification mark. The print and print are considered violated if the printed information cannot be read without the use of special means.
2. Changing the position of the seal, allowing you to access the internal elements and make a payment correction.
3. Mechanical damage to the device (impact, impact of weights, depressurization) or suspicion of it. In this case, it is necessary to carry out an urgent check of the gasometer in order to determine its ability for further operation, which is confirmed by the issuance of a new permit.
4. Reopening. A similar procedure is necessary for gas meters that have been idle for more than one calibration interval.
5. Suspicions of false information shown by the meter.

Consumers themselves must report to the gas supply authorities about the problems that have arisen and call specialists for an unscheduled examination. In some cases, the initiative for additional verification may also come from the relevant organization.

Frequency of checks of gas meters

In addition to the initial check, there is also a specially developed diagnostic schedule, which outlines the timing of periodic verification of gas meters.

The interval between such events is mandatory prescribed in the data sheet of the device. It also indicates the period during which the full performance of the gas metering device is guaranteed.

The date of the previous check can be found out by examining the seal of the gasometer under a magnifying glass. On the brand that is applied to it, the year and quarter of the procedure are put

The documents indicate the time of passing the diagnostic procedure and put a stamp certifying the suitability of the gasometer for operation.

The specified date of the planned inspection should not be neglected. If the device does not pass the control within the scheduled period, it is considered unusable, and the data taken from it may be invalidated.

In this case, the fee will be charged according to the average meter reading for the previous period or according to the standards prescribed in the contract. It is also possible to recalculate the already paid payment for blue fuel upwards.

For each brand of gas meter, a certain calibration interval is prescribed, which implies the maximum period of operation of the device before it is checked. Thus, the SG-SGK-1.6 model is designed for 8 years of operation, while the SGMB-1.6, Grand-1.6, SGBM-1.6 "Betar" models are designed for 12 years.

It should also be taken into account that the service life of a gasometer is calculated not from the date of sale, but from the date of its manufacture (PR 50.2.006-94 "GSI. The procedure for verifying measuring instruments", Ministry of Justice of the Russian Federation No. 640 21.07.94).

In the absence of a technical passport (for example, in the event of its loss), gas service specialists can independently determine the calibration interval of any meter using technical documentation and reference literature.

How is verification carried out without removal?

Gas services offer two options for control measures.

The traditional diagnostic

Normal verification takes place in two stages. After calling specialists and agreeing on the time of their arrival, the company's employees visit the apartment, where they remove the meter from, which is taken to the laboratory. Instead of the device, a temporary jumper is placed.

After the completion of the procedures, the workers again come to the house, where the device is installed, followed by sealing, after which the controller is considered put into operation.

The action taken may include the installation of a new power supply, as well as a complete preventive maintenance of the device, which is disassembled and cleaned, which significantly increases its service life.

Checking the gasometer at home

There is also a modern technology for checking devices, which is suitable for most models of gas meters SGB, NPM, SGMN, BK. It involves procedures for assessing their performance without removing them at the installation site, while seals and stickers remain intact.

To check the gas meter at home, special diagnostic devices are used, which are trusted only by highly qualified specialists

Checking gas meters without removal is carried out using special equipment that is connected to the gas network, which makes it possible to check the readings of gas controllers.

Such an examination is somewhat more expensive than the traditional one, but it can significantly reduce the procedure for determining the operability of the device. In addition, in this case, noise, pollution and other troubles associated with the dismantling of equipment are excluded.

To carry out the device verification procedure without removal at home, the user must ensure:

• Visual accessibility of the counter. If the appliance is hidden behind a kitchen set or hanging cabinet, it is necessary to remove or move away the interior items so that the specialist can see the window with the fuel consumption indicators.
• Free passage to the crane. Workers should be able to turn on and off the tap, which is installed on a pipe connected to a gas stove.
• Access to an electrical outlet. Near the junction of the gasometer with the pipe, there must be a source of electric current, which will be needed to turn on the special device.

However, such a survey also has a number of disadvantages. This method allows diagnosing only the general state of the meter, while a malfunction or damage to its individual parts may go unnoticed. In addition, this option is not suitable for all models of gas meters.

There are a number of models of gasometers (UBGS, OBOY and others), the examination of which is possible only after dismantling, carried out by specialized services

Regardless of the method of verification, upon completion, the user is issued an act on the results of the procedure and a receipt for payment.

Steps to complete verification

Having carried out the verification procedure with or without removal, the specialist makes a conclusion about the possibility of using the gasometer for another calibration interval.

If the test was carried out in the laboratory, the device recognized as working is installed back into place, while the workers who carry out the installation put a seal and brand on the junction of the device with the gas pipeline section

After that, a representative of the organization that conducted the survey issues a permit certificate, and the device is sealed with a verification mark. Comprehensive information is entered into the technical passport of the meter, certified by a signature and an image of the seal.

If deviations are detected between the readings of the device and the actual data on the consumed resources, the device is recognized as faulty, and the owner is issued a “Notice of unsuitability”. In this case, it is necessary to repair the gasometer or, preferably, purchase a new device.

Specialists draw up an act of checking and sealing the gasometer in two copies: one remains with the service provider, the second - with the owner of the device. After applying the seal, payment for gas is charged according to the readings of the device

Terms and cost of verification works

Checks of devices are carried out during the time period established by the laws and by-laws of the Russian Federation.

If the removal of the meter and other activities are carried out by an organization that has concluded an agreement with the owner of the apartment for the maintenance of in-house devices and networks, then the laboratory test period may take 15-30 days.

You should take care of the verification in advance by calling specialists 1-1.5 months before the date when the calibration interval expires

If the inspection without removal is carried out by a specialized company using high-tech equipment, the examinations are carried out much faster (within an hour), although at a higher cost.

According to legislative norms, control of gas meters is carried out at the expense of subscribers, who are also responsible for the good condition and correct operation of the devices. Based on this, the services of the company conducting the procedure for examining the device for gas consumption should be paid by the owners of the apartment.

The specific cost of the work varies depending on the region, the distance of the addressee and the type of device. Before calling a specialist, it is advisable to call the company and ask the manager or dispatcher about the prices for the service.

Without dismantling and transportation to a calibration organization, it is possible to test not only a gas flow meter. You will learn how verification is carried out by reading the article we recommend.
