Elements of metering devices for electricity, hot and cold water, gas operate in a constant mode, which leads to their rapid wear or complete failure. The performance of the components has a direct impact on the values ​​​​obtained, as well as the numbers in the payment receipts. Sooner or later, every owner asks himself the question - after how much to change the meters, what regulatory documents regulate this process? Terms can vary significantly depending on the technical characteristics and purpose of the meter.

Gas metering devices

The gas meter is a complex technical instrument. Over time, they wear out, some parts are deformed. As a result, the device gives incorrect readings - the values ​​\u200b\u200bcan be either significantly underestimated or overestimated. The first verification of the device is carried out within the time specified in technical passport.

The lack of periodic verification leads to undesirable consequences for the homeowner. The readings of such a gas meter will not be taken into account, and charges for the used Natural resources produced in accordance with regulations.

Usually a meter in an apartment or house is used for 10 years. The gas meter has its own service life, and it is counted from the moment of its manufacture, and not purchase or installation. The bandwidth of the device matters.

What are the devices?

• Industrial.
• Utilities.
• Household.

Devices differ from each other in terms of technical parameters, service life and design features. One of their main characteristics is the volume of gas that passes through the device per unit of time. Some devices installed in private houses or apartments have a service life of 20 years or more. The gas is passed through the device according to the parameters specified in the technical data sheet. This allows you to determine the type of system on which the device can be installed.

The homeowner is sometimes able to determine when to change gas meter. If, with the saved heating mode or operation of the stove, the parameters obtained during the month differ significantly, it is in the interests of the owner of the premises to carry out an unscheduled verification.

There are several factors that affect the service life and help to understand how many devices need to be changed:

• there is no dust filter or its cells do not meet the established standards;
• low throughput;
• increased humidity in the room;
• incorrect installation of the meter.

It is necessary to change the gas meter after 8-10 years. It is this period that is indicated in the technical passport of most devices used in everyday life.

But if the owner is unwilling to purchase a new meter, he can send the old meter to the laboratory for examination. If its ability to correctly determine the throughput is confirmed, then its further use is allowed. How long the verification takes depends on the availability of the services and the technical characteristics of the device, the approximate time is 20 days. While the meter is in the laboratory, the amount of payment will be calculated in accordance with the heated area.

An electricity meter is a device whose readings are taken into account when paying for electricity at the end of each month. Most consumers know only about its location in the room and few know about it. technical specifications. If new appliances have not appeared in the apartment lately, and the old ones are operated in the usual mode, then there should not be significant digital changes in the electricity bills.

When you need to change counters, the following signs can tell you about it:

• poor-quality rotation of the induction meter disk or its complete absence;
• the indicator of the electronic counter does not show the determined parameters;
• lack of tightness of the electric meter housing, the presence of through holes, chips or cracks;
• violation of the integrity of the sight glass;
• incorrect display of the amount of energy spent in electricity bills.

Often there are situations when the device works when all devices in the apartment are disconnected from the power source. In everyday life, this phenomenon is called "self-propelled". You can solve the problem with a simple experiment - you just need to turn off all the switches on the shield, leaving the input on. Electric meters are subject to immediate replacement if the disk on the meter continues to rotate. Otherwise, the device will continue to wind up unrealistic readings, and the homeowner will regularly pay receipts for electricity.

Each meter in the apartment must comply with the requirements of regulatory documents. One of them is the accuracy class. The parameters of only those devices are taken into account, the value of this standard of which is 2.5 or more. All other electricity meters are subject to immediate replacement.

Normal accuracy class parameters do not exclude errors in electricity bills. The relevant organization may unexpectedly present verification requirements to the owner of the premises due to the unreliability of the data received.

You should first check the meter:

• disconnect all appliances from the electricity sources in the apartment;
• the values ​​​​of electricity meters must be recorded;
• connect one device, the power consumption of which is well known (an excellent option is an ordinary light bulb);
• check the readings of the meter in an hour.

An increase in the digital parameters of the device by the expected value indicates that the device is in full working order. A small deviation in either direction is acceptable if it is within the specified error limits.

How often you need to change the meters, you can find out in the subscriber department of the power supply organization. An important determining parameter is the calibration interval. During this time period, the manufacturer guarantees the uninterrupted operation of the meter. The service life varies from 6 to 16 years. At the end of it, the homeowner changes the device to a new one or checks its serviceability in the power supply organization.

The consumption of hot and cold water is also controlled by meters. After how many years the device must be replaced, you can find out when buying the device. Its service life is indicated in the technical data sheet and depends on the model of the device.

For household needs, counters are used:

• electronic;
• mechanical.

Each water measuring device, by law, has a certain period of use, during which the verification services and the manufacturer guarantee the effectiveness of its operation. According to the law, water meters are installed on the corresponding water supply lines. A malfunction that occurs during operation becomes common cause incorrect data transfer. Before the release of metering devices, each manufacturer conducts tests by setting empirically guarantee period. A high-quality water meter has been operating without breakdowns for 20 years or more.

Controlling services are forced to change the meter in case of improper operation. The effective operation of accounting devices can be influenced by:

• impurities and foreign objects in the water;
• pressure drops.

To determine the damage that has occurred, an inter-verification interval is established - the time interval between the next checks of devices and their manufacture. With its help, consumption control services determine how often it is necessary to change water meters in a given room.

The verification period depends on the purpose of the device:

• cold water meter - 6 years;
• counter hot water- 4 years.

If, after investigation, it turns out that the device is not working properly, then the homeowners change the device to a new one. Hot water has a more negative effect on components, which explains the difference in the timing of verification.

Sometimes you have to change water meters before the next inspection is due. In what cases does this happen?

• If there are no objective reasons for a significant difference in monthly readings.
• If there is any doubt about the correct operation of the dial or movement indicator.

Only a specialist of an authorized organization can find out the cause of the malfunction. He will tell you if the meters need to be changed or if they need to be repaired. If a malfunction is found in the device, you should not postpone the purchase of a new one for a long time. The controlling authority will quickly detect damage to the meter. You still have to change water meters, otherwise a full recalculation will be made, which will result in a significant amount.

After how much to change the meters, you can check with the organizations that are responsible for the correct operation of metering devices. The owner of the premises, who correctly approaches the issues of regular verification, similarly avoids penalties. Whether it is necessary to change the meters in the near future, the technical passport attached to the device will tell. The terms of periodic verifications should be indicated in the documents issued by the controlling authorities.

Gas meters are special devices designed to record the consumption of liquefied or natural gas. Depending on the throughput, they are:

• household;
• household;
• industrial.

Each option has certain technical specifications and design features. The service life of a gas meter in an apartment or at work also differs.

Characteristics and types

The main characteristic of meters is the amount of gas passing through the meter per unit of time. In addition, the operating time of the devices is important. To find out what is the service life of a gas meter, you need to find out the data of its technical passport and operating conditions. On average, it is 20 years or more.

The throughput of the device is determined according to the parameters specified in its technical data sheet. It is also reflected in the marking of the gas meter, where the figure corresponds to the volume for which the meter is designed. For example, G6 is a device with a capacity of 6 m3 / h. It is installed in a system where the total gas demand of household appliances does not exceed this value. The service life of the G6 gas meter is indicated in the accompanying documents and depends on its manufacturer, but is at least 20 years. To confirm the serviceability, it should be regularly verified every 8-10 years.

Metering devices for the domestic sector

According to the principle of operation, gas flow control devices are divided into the following types:

• membrane;
• diaphragmatic;
• rotary;
• turbine.

Membrane meters are used for commercial accounting in the domestic and domestic sectors. The principle of their operation is based on a design feature consisting of several chambers. When gas enters, the membranes are displaced, and the counting mechanism is actuated by a reducer through a system of levers.

One of the options for a membrane-type household appliance is the NPM G4 meter with a throughput of 4 m3 / h. It is produced in two versions ─ left-handed and right-handed. The service life of the NPM G4 gas meter is indicated in the accompanying documents and is 20 years from the date of manufacture.

Operating conditions

However, such parameters are typical for devices that are used in ideal conditions. When operating in a standard apartment, meters can fail long before the end of their service life. Among the reasons are the following:

• the absence of a dust filter or the non-compliance of its cells with the established requirements;
• throughput is lower than necessary;
• excessive moisture content;
• violation during the installation of the metering device.

As a result, the service life of household gas meters may be reduced and not correspond to the data in the accompanying documents. Over time, due to damage or the selected resource, the gas flow meter will have to be replaced. To do this, you will need to purchase a new device and install it by contacting a specialized organization.

There are often times when consumers utilities pay more than the amount for which they spent resources. This is often the case with paying for gas.

According to the approved standards, payment is charged in accordance with the number of people living in an apartment or house. In this situation, the volume of actually consumed gas is not taken into account.

In any case, the amounts charged are greater than the cost of the resource used. Those homeowners who do not want to overpay every month should consider installing a gas meter.

Installing a gas meter

You will have to install it at your own expense, but these costs will pay off within a few months. This problem is especially relevant if the heating in the house is carried out from a gas boiler.

The counter is installed on the territory of personal housing, and therefore the owner himself puts it. Sets conditionally. It is strictly forbidden to carry out the installation and replacement of gas equipment to which the meter belongs.

The boundary of personal property and equipment of a gas company is a shut-off valve that shuts off the supply of blue fuel to a house or apartment. You do not have to pay for installation if the housing is departmental or municipal. But, since residents have to pay for utilities, it is necessary to require official homeowners to install metering devices not only for gas, but also for water and electricity.

It is worth consulting on this issue with a specialist who will carry out the installation.

Different equipment requires a certain type of device. It must be chosen in accordance with the power of the gas stove or boiler. The cost of a metering device ranges from 10 to 13 thousand rubles.

In addition, you have to pay an impressive amount for the installation work. If the gas pipeline scheme does not change at the same time, the meter is simply introduced into the system. But in special cases, for convenient viewing and maintenance of the device, it is necessary to change the relief of the pipeline using welding. Then the installation cost will be higher.

The right to work with gas equipment have specialists of licensed organizations. These jobs are associated with a risk to life.

Only specialists can produce them.

Flammable gas is constantly present in the gas pipeline, the flow of which must be stopped for the duration of the manipulations.

Work procedure:

Step 1. You need to apply to the organization that supplies gas near your home. The application must be accompanied by photocopies of the Certificate of ownership of the residential premises where the meter will be installed, personal documents.

Step 2. The master examines the conditions for installing the meter, studies the technical capabilities of the system. The supply pipes and connections must comply with the requirements of GOST.

Step 3 In the store of special gas equipment, we select the meter recommended for installation by the master. With a representative of the gas company, the volumes and types of work, their cost and the timing of installation are negotiated.

Step 4. After carrying out all the planned work, an acceptance certificate is drawn up and the entire amount is paid.

Step 5 Sealing the meter is a prerequisite for its legalization. Only the data of a verified and sealed device is the basis for charging payment for the consumed gas. The device can only be put into operation after a seal has been placed on it. Sealing is carried out by a representative of the management company that keeps records of the consumption of communal resources.

You must submit an application indicating the personal data of the owner of the property and his phone number. The application includes the model and serial number of the meter, the date of its launch, the name of the company that installed the device, and the figures of indicators at the time of installation. The passport of the meter and the results of the scheduled inspection of gas equipment are also attached. After consideration of the application, the time of arrival of a specialist for sealing is set with the owner of the housing.

According to the law Russian Federation"On Ensuring the Uniformity of Measurements", adopted in 1993, all homeowners must use the means of accounting for communal resources and provide them on time for verification and sealing. Only such devices are legal meters for the consumption of water, gas, electricity. Without a conclusion about its effectiveness and serviceability, the data are considered unreliable.

To check the device must be removed from the system and sent for testing. It can last up to 1 month. During this period, the calculation of costs is taken as the average monthly consumption rate and is calculated for each owner individually according to the data of the last 6 months before the removal of the device. This procedure is prescribed in the rules for the provision of public services to the population.

is a resource consumption meter. It is installed inside the dwelling, if it is a private residential building, or inside an apartment building. Replacement of a gas meter, as well as its installation, is carried out by accredited specialists who have permission to work with gas systems and equipment. The counter setting order as described above is retained. Only before this it is necessary to dismantle the old counter.

Certain rules for installing the meter must be observed:

• The distance between the meter and gas equipment (stove, heater) should not be less than 80 cm. The height above the floor level should not be less than 120 cm.
• The display or counter window must be clearly visible, the instrument must be accessible for viewing and maintenance.

If these conditions are met, then the homeowner has the right to choose the installation location of the device at his discretion. He purchases a counter for replacement at his own expense.

If the device is under warranty. That repair is free of charge. If the device is in good condition, and the battery in it is out of order and the meter does not give readings, the owner pays for its dismantling and installation after opening and replacing the battery. In addition, the device must be re-sealed.

It is advantageous to purchase meters from a gas company conducting installation work. They put the device under warranty and are responsible for its operation and installation.

Reasons for replacing gas meters

1. The gas meter is replaced after the expiration of the calibration period.
2. When transferring the meter to another place due to a change in the scheme of the gas pipeline inside the premises.

Only specialists with a permit to work with gas equipment are entitled to replace the meter. It is forbidden to carry out these works independently. This is due to the risk of explosion or gas leakage. Replacing the meter is always associated with the introduction into the gas pipe where the gas flows. There are mandatory rules for carrying out these works. Their violation is dangerous to the lives of others.

To replace the meter, an application is submitted to the gas service, which serves the house and controls the operation of all equipment. During the work, a representative of the controlling company must take meter readings, and then be present during the sealing. Thus, controversial questions about the presence of a seal before removing the device, about the readings and the date of launch of the new counter will disappear.

The transfer of the metering device may be associated with the inconvenience of taking readings in winter time if he was outside. Migration changes the original project.

Counters designed for outdoor installation are different from indoor ones. They withstand large temperature fluctuations from low frost to heat. The meter for room installation is cheaper and simpler in design.

The installation of a meter is mandatory, this requirement is prescribed by law. Installing a gas meter requires significant costs for installation, verification, replacement, sealing. But these expenses cannot be avoided if you use natural gas for space heating and cooking. Also, gas equipment is installed in the bathroom for heating water.

The counter can be moved, on the contrary, from the room to the street.

The choice of a new replacement device must take into account all the power requirements of the equipment used.

Service life of a gas meter

Gas equipment is constantly exposed to the working environment. Therefore, the replacement of the meter is mandatory after the expiration of its service life. This period for different models can be from 8 to 10 years.

If the meter is working, to confirm its performance, the meter for research is sent to the laboratory. The conclusion allows its legal operation to continue. Checking the meter when replacing should not last longer than 2 weeks. During this period, the average payment is calculated.

You can replace the battery in the meter yourself. It is located under the body of the device. After replacing the battery, the meter must be sealed

Please answer the following questions:

– Who should buy new meters?

How long does it take to change them?

- Do I need to pay gas services for the installation of a meter and how much does it cost? T. F. PAVLYUCHENKO (Belovsky district).

“The residents of house No. 3 on Novostroyka Street in the village of Korenevo are contacting you. We have been living with natural gas for four years. Gas meters manufactured in 2000, expiration date - 20 years. But we are forced to change them, explaining that their service life has expired. We do not find defects and shortcomings. What should we do: change meters or use old ones after verification? Who is supposed to take them for verification and pay for it? N. G. NIFONTOVA (p. Korenevo).

Deputy answers CEO OAO Kurskregiongaz Yuri MIKHAILOV: “In accordance with the Law of the Russian Federation No. 4871-I dated April 27, 1993 “On Ensuring the Uniformity of Measurements”, legal and individuals, using measuring instruments for the purpose of operation, are obliged to submit them in a timely manner for verification. Verification is a set of operations performed by the bodies of the state metrological service in order to determine and confirm the compliance of the measuring instrument (in this case, the gas flow meter) with the established technical requirements.

Delivery of measuring instruments for verification is provided by the owners of these instruments (clause 3.16 of the Procedure for Verification of Measuring Instruments, approved by Order of the State Standard of the Russian Federation dated July 18, 1994 No. 125).

Based on the foregoing, the current legislation of the Russian Federation and the contract for the sale of natural gas, the buyer of natural gas must take measures to ensure reliable accounting of the volume of gas consumed. That is, in the event of the expiration of the calibration interval established by the manufacturer of the metering device, provide the measuring instrument for the next verification to obtain a conclusion on its suitability for further measurement.

In addition, in accordance with paragraph 2.9. of the Gas Metering Rules (approved by the Ministry of Fuel and Energy of the Russian Federation on October 14, 1996), the amount of gas sold to the population is metered according to gas meters or on the basis of gas consumption rates (for cooking, hot water and heating, if there are local heating systems). Thus, after the expiration of the verification period for the natural gas meter installed in the household, charging for the consumed gas in accordance with paragraph 31 of the Rules for the provision of public services to citizens (approved by Decree of the Government of the Russian Federation No. 307 of May 23, 2006) and paragraph 25 of the Rules for the supply of gas to meet the household needs of citizens (approved by Decree of the Government of the Russian Federation No. 549 of July 21, 2008) will be carried out according to the current gas consumption standards until the date of installation of a verified meter, which is also established in paragraph 3.2. contracts for the purchase and sale of natural gas.

The removal and installation of gas meters in the Kursk region is carried out by specialized organizations at the expense of the owner of the gas meter. To ensure reliable gas metering, it is necessary, in the interests of all parties, to resolve the issue of meter verification as soon as possible.

Who carries out the removal and installation of gas meters in Kursk? The topic is not disclosed!

Who calibrates gas meters of gas brand RL G4 in Kursk

According to the old laws "On METROLOGY", the seller had to measure the quantity of goods - this is understandable even now, especially for mass quantities: sugar, gasoline, mobile communications. According to the constitution, it is impossible to create laws in the country that worsen financial situation citizens. My Izhevsk counter has a resource of 20 years. The calibration interval has ended. The preventive measures he was supposed to take were not done. The meter has not been verified. There are no repair shops in Kursk. (All you need to do is rinse it off from dirt. Izhevsk plant stopped producing counters - the enterprise goes bankrupt. It’s not up to Kalashnikov assault rifles. Other counters don’t fit in size. I’m not talking about how difficult it is to remove and install it. It’s called. It’s necessary we still have to stock up on our Kalashnikovs.

The gas meter must monitor gas suppliers and not the owner of the meter because in its interests and for the verification or change of the meter, the consumer must pay when he is provided with the account, the consumer is not obliged to independently monitor the expiration of the gas meter for which we pay for the iaminers once a year so that the gas workers are thinking THIS IS YOUR RESPONSIBILITY, THANK YOU

To find out when to change the gas meter, you need to look into the meter's passport, the service life is written there (for example, on mine it is ten years). Again, depending on the model, verification is carried out (once every five years usually, sometimes every three years, depending on the model of the meter). In general, you don’t have to worry about this, when the time comes, you will be sent a notification that it’s time for the meter to be verified (it comes with a receipt, there is also a phone number to call). When this very notification came to me, I called, the next day specialists came, removed my counter, installed their own, exactly the same, and about a month later they changed places back. If the meter has not passed verification, then they draw up an act (I know this for sure, because the neighbor had such a problem), in fact, that's all, after the act you will have to buy a new meter. To summarize, there is no point in worrying about the timing, the gas industry will remind you. Usually the service life is ten years, but if the verification passes, then they can increase it.

There is no need to confuse the verification of a gas meter and its replacement, verification can be once every 5 years and once every 10 years, after as long as it is established by regulatory enactments.

The replacement of the gas meter is carried out in two cases, either its malfunction detected during operation or verification, or the end of the dial of the accrual resource - usually no counters for the second round are launched!

Therefore, we can safely say that the gas meter is not changed at all, since they rarely break, and the dial resource is enough for a very long time.

The period during which a gas meter is considered "working" is set by the manufacturer of this meter. The so-called product warranty. This period is prescribed in the passport of the technical device (in our case, a gas meter). As a rule, this period varies from 5 to 12 years. However, this does not mean that the counter is necessary. Enough to just check. Of course, not on our own, but by specialists. And the full service life with proper operation can reach 20-25 years.
