Installation of gas meters: who pays? Instructions + Video

How does commissioning take place?

After installation, gas service specialists must check the functionality of the meter.
The following factors are taken into account:

the presence of interference during the passage of fuel through the mechanisms of the device;
counter performance;
no gas leaks.

In addition, fuel consumption is measured.

Upon completion of control activities, a report on the work performed is drawn up, which indicates the following data:

place and date of installation;
gasometer serial number;
Full name and contact details of the employees who carried out the installation;
device performance at the time of installation;
time of scheduled verification of the gas controller;
smooth running of the meter's star mechanism.

The document is drawn up in two copies: one is issued to the apartment owner, the other is transferred to the gas service. The client also signs an acceptance certificate for the work performed (also in two copies). The specialist is required to fill out the device commissioning certificate and the gas meter maintenance agreement (such papers must be drawn up in triplicate).

When turning on a newly installed device, it is important to expel the air from the system using gas. To do this, you need to sequentially open the gas at the inlet and then at the outlet, which will avoid damage to the gasometer mechanism from the shock load during first use

How to choose a gas meter

Despite the fact that in order to approve the project for installing a metering device, it is necessary to provide a data sheet for the flow meter, the choice of equipment should be made only after consultation with specialists. You should definitely inquire about the list of approved devices, since unlicensed devices will not be put into operation.

In order to select a flow meter, you should take into account its technical characteristics, especially paying attention to two criteria: throughput and type of device

The first criterion depends on the number and power of gas appliances installed in the house. For one slab, for example, a throughput of 1.6 m3/hour is sufficient. This parameter is indicated on the front panel and can be found out by looking at the value indicated after the letter “G”, that is, in this case you need a device marked G1.6.

The choice of meter depends on the throughput of gas appliances. For example, if for a gas stove it ranges from 0.015 to 1.2 m3/hour, then a meter with parameters of 1.6 m3/hour is optimal. In the event that several devices are installed and operated, then the minimum values of the least powerful and the maximum data of the highest consumption should be taken into account.

But you need to take into account that choosing an ideal flow meter for such a requirement is often an impossible task, so maximum values are taken into account. For example, if the minimum consumption of the stove is 0.015 m3/hour, and the maximum throughput of the boiler is 3.6 m3/hour, then you should purchase a meter marked G4

However, it is imperative to take into account the fact that the meter will be allowed to be installed if the deviation in the minimum value does not exceed 0.005 m3/hour. Otherwise, it may be necessary to install separate metering devices and, as a result, maintain two separate personal accounts

Main types of household gas meters

When choosing a meter, you should definitely take into account its type, which determines the principle of its operation, as well as the accuracy of the data obtained. Based on this criterion, individual consumers can choose devices:

membrane These gas meters are distinguished by their low price, high reliability and completely reliable values. But they are very noisy devices;
rotary devices. These devices are popular because of their compact size and fairly low price, but they have a short service life and are not highly accurate in the measurements obtained;
ultrasonic devices. These meters are electronic devices and have high measurement accuracy. They are quite compact, silent and can be integrated into an overall system for remote data transfer.

Also, when choosing a gas meter, you should take into account its installation location, since these devices are right- and left-handed

It is also necessary to take into account what section of the pipe the installation will be carried out on: horizontal or vertical. You also need to decide on the location of the gas meter: in the house, in a warm, heated room, or on the street

In the latter case, you should buy a device with thermal correction, as evidenced by the letter “T” on the front panel of the device, indicated next to the throughput of the device.

Particular attention should be paid to the date of manufacture of the meter, since it is the starting point for determining the verification interval, which is individual and ranges from 3 to 15 years

What metering devices are allowed for installation?

To understand which gas meters are allowed for installation, you need to familiarize yourself with the list of acceptable metering devices in the State Register of Measuring Instruments. Gas workers recommend that users install “smart” meters that not only measure gas consumption, but also transmit metering data to the relevant organizations without the participation of the consumer.

When choosing a gas meter, it is important to pay attention to its technical characteristics and operating features. The device has markings that indicate how much fuel it can pass in one hour:

● G1.6 – from 1.6 to 2.5 m 3 / h;

● G2.5 – from 2.5 to 4 cubes;

● G4 – within 4–6 cubic meters.

For example, if the apartment has a stove with a consumption of 1.56 m 3 /h and a water heater with a consumption of 2.5 m 3 /h, then the consumer needs a G4 device. There are also more powerful options that are used when individual heating is available. In the Mosoblgaz online store you can choose a meter that suits your needs. We offer customers a wide selection of models, including devices with a smart card and GPRS module.

Recommendations for the effective installation of a gas meter in an apartment

Since the mass privatization of the housing stock in all regions of Russia, installing a gas meter in an apartment has become a pressing issue. Today, almost every apartment has its own gas metering device.

For those who have not yet purchased such a device, it is important to determine which gas meter is best to install in the apartment. As practice has shown, the use of such devices has a good effect on saving blue fuel

You can choose the one you need yourself, just understand the principle of its operation. The equipment passes gas through itself, accurately counting how many cubic meters have passed in a specific time.

What type of device to choose

Is the installation of gas metering devices required by law? Yes, since 2009 there has been a decree on the mandatory installation of gas meters. Does this benefit the government or solely the citizens? Increasing gas prices encourages us to save, and the government can thereby reduce the percentage of wasteful gas consumption.

Before installing the meter, decide on its type. They are distinguished depending on their purpose, that is, the place of use. It is not advisable to buy devices of the same type for an enterprise and a private residential area. Don't forget that the cost of installing a gas meter also depends on its type. The main types of devices are:

The first three types are installed in enterprises, but a membrane gas meter is suitable for an apartment or a private house. The membrane type is one of the newest on the market, and has also managed to take a position as reliable and practical. Its main advantage is that it does not allow gas to pass through, which is not the case for consumers using other types of devices.

When choosing the right type, pay attention to the following factors:

lifetime;
the number of gas appliances in a private house or apartment;
gas consumption per hour of operation of the gas appliance (indicated in the passport);
location of the gas supply pipe (depending on this, choose a device with a right or left supply).

Is it possible to guarantee long-term operation of a gas device? No, but an installed meter can last a long time if it is chosen correctly. The date of its production is important, since the counters are checked against it. Old-style models are verified once every 5 years, and new models - every 12 years. The causes of breakdowns are as follows:

incorrect choice of device type;
installation performed incorrectly;
high moisture level in the meter;
there is no filter to catch dust;
gas is consumed in volumes that the device cannot handle.

The costs of installing the device are borne by the residents. How much installation costs directly depends on the nature of the work and the complexity of the installation. On average, you will have to spend from three to eight thousand rubles. Installing a gas meter in an apartment will cost more if welding work is carried out. The cost is affected by the length of the gas pipes and the number of devices consuming blue fuel.

Installation procedure

It is recommended to install a gas meter according to specific rules in order to avoid troubles with gas service representatives. Do I need to inform the specified service about my desire to install a meter in my apartment? Yes, without this you cannot avoid a fine. To find out where the nearest service branch is located, look at the address on the back of your receipt. Their range of services includes the provision of specialist services for the installation of the described devices. Therefore, we submit an application for installation along with the following documents:

passport of the owner of the residential property;
receipt for payment for gas use for the previous month;
gasification project;
instrument maintenance agreement;
lease agreement or certificate of ownership.

Free 24/7 legal support by phone:

the room must have natural ventilation (windows, doors, exhaust hood);
It is forbidden to place counters above the stove; they are placed to the left or right of it;
the distance from the stove to the device is 40 centimeters;
distance from the meter to the ceiling - 160 centimeters;
You cannot place the meter closer than 3-5 centimeters from the wall.

The outdoor installation procedure involves a canopy or box for the reader. Is it possible to do without a master? No, as this may affect your safety. The installer knows how to properly install the device, maintaining safety for all residents of the apartment building. The gas service must supply the installer, but you can choose one yourself.

Conclusions and useful video on the topic

Which is better, buy a new gas meter or check the one you have:

What you should pay attention to when installing a gas meter:

Several gas meters can be installed in one room at once. The only problem is that sometimes this cannot be done without rearrangements. The consumer will do the right thing if during installation he expresses his point of view, but still listens to the master with the opposite opinion.

A gas meter will most likely not be installed in a poorly ventilated place or at a great distance from a window, but theoretically the device can be moved outside.

Maintenance of gas meters

According to the maintenance agreement between the consumer and the gas distribution company, the latter is obliged to periodically monitor not only the metering device, but also the gas pipeline, as well as all devices connected to it.

The purpose of such control is to prevent emergency situations, therefore it includes:

visual inspection of equipment;
checking the tightness of connections and the operating condition of devices;
testing for traction;
carrying out minor repairs and maintenance of working units;
detection of gas leaks, etc.

An important aspect of maintenance is monitoring the serviceability of devices. If problems are identified, the specialist makes a verdict to replace the equipment, even if its inspection period has not yet arrived. It should be noted that the cost of replacing a gas meter

, although it affects the consumer’s wallet, is completely justified, since not only the accuracy of accounting, but also the safety of people depends on the functioning of the device. It should also be noted that when the deadline for inter-verification occurs or when repairs are necessary, the consumer often prefers to replace the old meter with a new device. The reason for this decision is obvious and is related to the fact that dealing with these issues is often more expensive and time-consuming than simply installing a new gas meter.

Rules for placing household gas meters

The issue of placement of household meters is especially relevant at this time due to the fact that standards for the installation of gas meters create a lot of problems when planning a kitchen. According to SNiP SP 42-101-2003: The distance from the installation sites of meters to gas equipment is taken in accordance with the requirements and recommendations of manufacturers set out in the meter passports.

If there is no such data in the passport, then the distance to the slab is at least 0.8 m. Vertical - 1.6 m from the floor. This requirement spoils the entire interior of the kitchen. Many modern counters have placement requirements specified in their passports, because... for example, to install a Grand-4 meter, it is enough to step back only 5 cm from the stove. In cases where the distance from the installation sites of meters to gas equipment is not stated in the meter passports, then you will have to comply with the requirements of SNiP. Let's look at the rules for placing household meters.

To quantitatively record the gas mixture passing through a certain section of the pipeline per unit of time, special gas metering devices are used at the household level - gas meters. Installation of meters is provided based on the conditions of ease of installation, maintenance and repair. The installation height of meters, as a rule, should be 1.6 m from the floor level of the room or ground.

In order to avoid corrosion damage to the meter's coating, when installing it, a gap (2 - 5 cm) should be provided between the meter and the structure of the building (structure) or support.

Installation of the meter indoors is provided outside the zone of heat and moisture release (from a stove, sink, etc.) in naturally ventilated places. It is not recommended to install meters in stagnant areas of the room (areas of the room fenced off from the ventilation duct or window, niches, etc.).

Pros and cons of installation

Having a meter has positive and negative sides. If you install measuring devices, the advantages will be as follows:

payment is calculated for the actual volume of gas consumed;
in the summer months, resource consumption decreases if there is a gas water heater.

The disadvantages of the counter are the following:

you have to pay a considerable amount of money for the device and its installation;
It is necessary to carry out scheduled checks of the metering device for serviceability in a timely manner.

Only employees of specialized organizations with permission to do this work should install devices.

It is strictly forbidden to install the meter yourself and involve non-professionals.

Gas meter installation

1. How to choose a gas meter
2. Installing a gas meter yourself

By installing a gas meter, you don’t have to worry about whether you will go beyond the limited volumes of gas consumption or not. In addition, a gas meter makes it easy to control the consumption of blue fuel and, if necessary, reduce it, thereby taking appropriate measures to save financial resources in a timely manner.

This article will tell you about the rules for installing a gas meter with your own hands and how to choose it correctly depending on the operating conditions.

How to choose a gas meter

Installing a gas meter today is a necessary measure in order not to cost a penny for consuming natural or liquefied gas in excess of the norm. However, before installing a gas meter with your own hands, you need to choose it correctly.

Today you can buy four types of gas meters on sale:

Turbine;
Rotary;
Membrane and vortex.

The operating principle of all of the above types of gas meters is different, as is the method of monitoring the consumption of blue fuel. For example, in a membrane gas meter, a special membrane is installed, which, relatively speaking, divides the gas passing through the meter through the membrane into certain “portions”.

Membrane gas meters are easy to use, their price is low, which is due to their rather simple design and manufacture. The only disadvantage of gas membrane meters is that they do not withstand loads, both temporary and permanent.

The rotary gas meter uses an eight-shaped rotor, which is capable of passing a large amount of gas through itself. Prices for rotary gas meters are higher than for any other types of gas meters, and this is due primarily to the expensive materials that are used in the manufacture of rotary gas meters.

Turbine gas meters, as well as membrane meters, have a very simple design. The gas passing through the turbine meter causes the membrane installed inside it to rotate, which in turn causes the reading mechanism for quantitative gas consumption.

Vortex gas meters have one feature: they are dependent on an external power source of 220 Volts, since piezoelectric or hot-wire sensors are installed inside them, reading the amount of blue fuel passing through them.

Do-it-yourself gas meter installation

So, having selected the desired gas meter, you can begin installing it. However, for this you need to know certain standards for installing a gas meter in an apartment. Therefore, first of all, you need to draw up and submit an application for installation of a gas meter to the regional gas office.

You cannot take and install a gas meter yourself without notifying the gas supply organization. In addition, we should not forget that any gas equipment, be it a stove or a meter, is an object of increased danger, so control over the installation of a gas meter must be entrusted exclusively to specialists from the gas service.

In addition, after installing the gas meter and checking it, employees of the same gas service must seal it, and after all this red tape, issue a certificate of putting the gas meter into operation.

Gas meter installation standards

In any case, installing a gas meter yourself must be carried out strictly according to the issued project. The gas project indicates not only the location, but also the installation height of the gas meter, the possibility of location near various electrical appliances, etc.

In addition, the rules for installing a gas meter also include a certain distance to heating devices, agreed upon radii of pipe turns, and much more. Therefore, under no circumstances should you ignore the project for installing a gas meter, since all the work associated with its installation will be done in vain, and the work will not be accepted by the relevant authorities. In other words, everything will have to be redone in the end according to the gas project.

In most cases, there are generally accepted standards for installing a gas meter:

How to install a gas meter correctly: procedure

Due to the fact that gas meters are high-risk devices, the question of how to install or change a gas meter should be entrusted to professionals. The installation is carried out by representatives of the gas service or specialized companies that have SRO approval to perform this type of work. Installation is carried out on the basis of an agreement concluded with the consumer.

Documents for installation

Before proceeding with installation, the consumer needs to contact Gorgaz at their place of residence, write an application and present a package of documents:

Reasons and procedure for replacing a gas meter

Most citizens of the Russian Federation calculate payments for the use of resources based on gas, electricity and water meter readings. Any measuring equipment has its own specific service life, after which it must be replaced. In addition, in some cases, when after the next verification the device is found unusable, a new one is also installed in its place. Replacement of the gas meter is carried out in accordance with these rules, and is carried out in accordance with the established law.

Reasons for replacement and the need to pay for the operation

After the expiration of the service life (operation) of the device;
In the event that the meter has not passed verification.

One of the main questions that concerns our citizens is whether they need to pay for verification or replacement of a gas meter. And if the verification of such devices in most cases is practically free, then completely different rules apply regarding the installation of a new one.

To understand who pays for the installation of a new device, you need to pay attention to the type of housing in which it is located:

In a private house. In this case, the clear answer to the question at whose expense the replacement will be made is - at the expense of the owner of the property. In the event that the owner of a residential building is an individual or legal entity, the costs definitely fall on him;
In the apartment. If this apartment is privatized, changing the metering device is carried out for a fee at the expense of its owner. If the premises are municipal, that is, owned by the state and provided for a citizen to live in, the installation of a gas meter is carried out at the expense of the state.

In addition, for certain categories of citizens, the law establishes a procedure for free replacement. These include:

WWII veterans;
Large families;
Low-income people who have reached retirement age.

Replacement procedure and cost

Cost of the meter. It can vary depending on the type of device and amount to up to 30 thousand rubles;
Direct installation procedure. Its value depends on the region (for example, in Moscow it will be about 2500-3000 rubles). If during the replacement process it is necessary to change the gas pipeline system, another 400-5000 rubles will be added, depending on whether gas water heaters and stoves are installed in the house.

What documents are needed to replace the device? Their list is presented as follows:

Passport of the owner of the house or apartment;
Technical data sheet of the new device;
Documents for ownership of real estate (state certificate, purchase and sale or gift agreement, etc.), house register;
Technical plan of the building;
Gasification project;
Application for replacement.

The procedure for carrying out the necessary steps to change the gas meter is as follows:

Filling out an application and sending it to the gas utility, which is responsible for the territorial area where your house or apartment is located; Attachment to the application of the necessary documents (ownership, etc.); A specialist will visit your premises and, based on special technical parameters, issue an opinion on what type of meter can be installed. In addition, the owner is informed of the amount for the replacement service; Purchase the meter itself. A very important point is to buy it in a specialized store. Sometimes, wanting to save money, citizens buy the device secondhand, on the market, but such a procedure is fraught with the possibility of purchasing a faulty meter or one with any defects.

Particular attention should be paid to its service life indicated in the passport. Since its duration is counted not from the moment the work begins, but from the release by the manufacturer; Installing the meter, signing the work acceptance certificate and making payment; Putting the device into operation by sealing it.

Cost of a gas meter for a private home

Before installing a meter, every consumer asks the question of how much a gas meter costs for a private home. To get an answer, simply looking at the digital prices in the catalogs of trading companies will not be enough. It is necessary to understand the operating principle of metering devices, compare different options, get acquainted with the opinions of experienced users, and only then evaluate the cost of a particular device.

The average price of household gas meters varies between 2000-3000 rubles

The average price level for household gas meters is 2000-3000 rubles.

These are domestically produced membrane models with a mechanical counting method and a nominal throughput of up to 6 m3/h.

For example, a VK G4 gas meter costs 2,200 rubles; The VK G4T device has a price of 3,400 rubles, where “T” means the presence of a temperature compensation mechanism.

The price of “smart” meters reaches 10,000 rubles.

The cost of a gas meter is affected by the throughput and counting mechanism

The increase in the cost of a gas device, in addition to the features of the metering mechanism, is largely influenced by the throughput of the device: the larger it is, the higher the price of the meter.

Popular models of gas meters for private homes

Models that have proven themselves well during operation are becoming popular. Quite often, even the price fades into the background. If both indicators suit the consumer, demand actively increases.

“Grand” meters should be classified as such devices. They may have different bandwidths. The distinctive characteristics of these devices are:

small sizes;
energy independence;
easy installation;
resistance to temperatures and dirt;
accuracy of readings;
long warranty period (12 years).

Those models that have proven themselves become popular among consumers

Electronic meters "Grand" very rarely fail. They can be mounted in both vertical and horizontal positions.

One of the best gas meters for a private home are also Betar gas meters. The models have a fairly high technical level, many are equipped with a heat correction function. The devices are small-sized and can be installed in both vertical and horizontal planes. The model range includes devices with remote control that can be connected to an autonomous Smart Home system.

Gas meter: which one is better for a private home

When choosing a gas meter for a private home, you must consider the following indicators:

number of gas equipment units;
family composition;
meter installation location.

You need to start choosing a gas meter for a private home after determining its location

The volume of gas used depends on the number of consumers and types of installed gas appliances. If only a water heater and a gas stove are placed in the house, a meter with a throughput capacity of up to 2.5 m3/h is sufficient. It is worth choosing counters marked G-1.6. If the heating in the house is also gas, a G-4 or G-6 meter will do.

Before choosing a gas meter for a private home, you need to determine its location. When hanging externally, the influence of temperatures increases; the range should be -40 – +50 °C. Therefore, it is necessary to carefully study the passport data before purchasing the device.

An important option for an outdoor gas meter is thermoregulation. The built-in function will eliminate the need to use an additional coefficient when calculating payment

How to check a gas meter?

If you have to undergo a scheduled gas meter check, here's how to proceed:

Contact the organization with which you have an agreement and submit a request for verification.
Take the application to the gas company or other service organization.
Wait for the call and agree on the date and time of your visit to the specialist.
Upon arrival of the specialist, check his documents to make sure that he is qualified to work with such equipment.
Give a specialist the opportunity to examine the metering device.
Decide whether you are ready to pay for the work to check the gas meter at home, or whether it needs to be removed and taken to a laboratory.
Wait for the result and the drawing up of an inspection report.
Based on the results obtained, make a decision about replacing the gas meter or leaving the old device in operation. From a separate article you will learn all the features of the procedure for replacing or repairing a gas meter.
Pay for the services of a specialist.

Where to contact?

In order to carry out a scheduled or extraordinary check of the gas meter, you must contact your regional gas service or other service organization with which you have an agreement.

What documents are needed in 2021?

In order for the regional gas service to carry out an inspection, you must submit an application.

For verification, you will need a passport of the owner of the premises or the person living in it

The passport data will be recorded in the verification report. Also, you will need a passport for the gas meter so that the specialist can pay attention to the characteristics of the device, as well as identify when the last check took place. If an apartment building or you personally have entered into an agreement for the maintenance of a metering device with a specific service organization, then in this case, when a specialist appears, you are required to provide a service agreement drawn up in your name.

Drawing up an application

The application is drawn up in free form. But often, gas company employees offer their own ready-made samples, based on which this document can be drawn up. It is drawn up on an A4 sheet.

The header indicates where this document is sent. The name and address of the gas service, as well as the applicant’s full name, passport details and registration address.
In the middle of the line the name “application” is indicated; the date of the gas meter inspection is indicated.
Below you need to indicate a request to consider the application for an inspection of the metering device.
Date and signature are added.

If you have entered into an agreement with a service company, then writing an application is an unnecessary procedure.

You will need to submit your application in person or by phone. A specialist will arrive at the appointed time and will conduct research and diagnostic work using special instruments.

Deadlines

Gas meters are checked within the time limits established by law. Government Decree No. 549, namely clause 22 (g), states that the gas supplier is obliged to respond to the consumer’s application within 5 working days.

If the removal of the meter and subsequent procedures are carried out by an organization that once entered into a maintenance agreement with a citizen, then all procedures will take from 15 to 30 days.
If a citizen asked for an inspection without removing the meter, and a special company is doing this, then in this case the examination will go much faster. Just a few days.

Payment for work and their cost

Payment for work related to installation, removal, and transportation of a gas appliance is borne by the owner of the premises.

On average, checking the meter will cost from 1,500 to 2,500 rubles, depending on the city of your residence. If the meter has a magnetic card, the check amount will be slightly more expensive.

If the device does not pass the test, then replacing it will cost from 3,000 to 4,000 rubles.

results

A specialist must confirm the suitability of the equipment for use. Or, it recognizes it as unsuitable for further use. If the measuring device is in good condition, the specialist issues a certificate, and a seal with a special verification mark is installed on the meter.

Information about the inspection is entered into the technical passport of the device, certified by a signature and an image of the assigned mark.

Is it possible to install for free?

Federal law and Government Decrees require owners of private houses and apartments to re-equip their household gas pipelines. Due to the fairly high cost, which has a significant impact on the family budget, not all categories of citizens can meet the deadline.

There are several options that significantly ease the financial burden:

Free for council housing tenants. If a sales organization makes a claim against a person living in an apartment, it is necessary to contact the municipality with a written complaint.
Installment plan based on Federal Law No. 261. The option provides distribution of costs for a period of up to 5 years. You need to apply to the gas distribution company. Repayment involves making equal shares at the refinancing rate of the Central Bank of the Russian Federation. Early repayment is possible.

It is a common belief that gas meters are installed free of charge for pensioners. Indeed, in some regions of Russia there is a provision that provides compensation for part of the installation cost of IPU for a preferential category of citizens. You will have to pay more often, because reimbursement is based on the costs incurred. The exact list of persons included in the list can be found in the social protection department of a particular territory.

Cost of installation services

Since the gas flow controller device is considered the property of the apartment owner, he is obliged to purchase it at his own expense, as well as reimburse the costs of its installation.

Consumer experience shows that installing a gas meter can reduce monthly gas payments by 30-50%. It is especially beneficial to use the device if more than 4-5 people live in the apartment

The cost of installation may vary, since this value is influenced by a number of factors, namely:

the presence of household appliances and devices that require blue fuel to function. These include a gas water heater, water heater, gas stove, boiler;
carrying out welding work or lack thereof;
the length of the pipes on which the meter is mounted;
payment for materials and equipment (hoses, fittings).

At the moment, connecting the device in a room where there is only a gas stove costs on average 3000-5000 rubles, but if the apartment is equipped with a gas water heater or other equipment, the price approximately doubles.

As practice shows, the funds spent on purchasing the device and its installation pay off within one year. But it’s still better to make an initial calculation, especially if 1-2 people live in the apartment, and the only appliances are a hob.
