How is the calibration of gas meters

Installing a gas meter in an apartment can significantly reduce energy costs. This is especially true if a person lives alone and consumes little fuel. Gas meters for a private house and apartment come in different models and manufacturers.

How to choose a gas meter

Gas meters are distinguished by size, principle of operation, design, purpose, cost.

You don't have to buy the most expensive model - it is important that the meter works without breakdownsotherwise, you can get a penalty for using a broken device.

Varieties according to the principle of work

By the principle of operation, you can find the following types of counters:

• Membrane. This type was invented a long time ago, but still has not lost its relevance. Models are inexpensive, can serve for a long time, but there are instances that break down quickly and begin to creak. The accuracy of the data is difficult to verify.
• Electronic. This is a more reliable gas meter for an apartment, it shows accurate data, but it costs almost 2 times more than the previous one. The device is checked once every 10 to 12 years.
• Rotary. Also considered very reliable, suitable for apartments. They check it every 5 years. Due to their low cost, rotary models are the most common.

If the counter is needed only for a column and a stove, it is recommended to buy a rotary or electronic one.

For apartment

For installation in an apartment, it is recommended to pay attention to model with thermocorrector... These are the most accurate instruments, so you don't have to overpay for fuel.

Before choosing a meter for an apartment, you need to decide on the level of its noise, since the location in the living room will cause inconvenience.

For a private house

Thermal correction of readings is also necessary for outdoor devices to reduce the influence of external temperatures on the data.

If the house has autonomous heating, a membrane or rotary gas meter is installed. If only the column and the plate are enough rotary or electronic.

Before choosing a gas meter for a private house, should also envisage:

• the throughput of the device;
• temperature range in which the device will be used;
• interval between verifications;
• the degree of reliability of the device readings.

The degree of reliability is one of the most important indicators, since it directly affects the cost of services. If suddenly the device starts to show more gas consumption, you may not notice it.

What are the advantages of a smart meter

Intelligent Gas Meter capable:

• independently determine the characteristics of household gas entering the apartment;
• carry out self-diagnostics;
• measure the volume of gas;
• record external influences and adjust their work in accordance with them.

In addition, the devices have reliable protection against unauthorized access, are easy to install, and automatically transmit readings.

Smart meters are manufactured by both foreign and domestic companies. At the moment, foreign models are winning competition in the market, as they provide wider functionality.

Installation and replacement of a gas meter

All gas appliances and equipment must be installed by qualified technicianswho have permission to do such work. Before installing the device, you must supply application to the gas industryto obtain permission for installation.

Who should install

You cannot choose a master, focusing only on the cheapness of the work. it it may be a swindlerwho does not have the appropriate skills and uses cheap materials when inserting a counter.

After installation, the master is obliged to compose certificate of completion... This document may subsequently be needed to show the calibration workers.

To apply, you must bring the following documentation:

• passport;
• a document certifying the right to own an apartment or a private house;
• paid receipt for gas as confirmation of the absence of debt.

If a tenant submits an application, a written confirmation of the owner of the apartment for the installation of a meter is required.

Place for installation

Before installing the gas meter a visit of the master is scheduledwho takes the necessary measurements, determines the optimal place for installation... It usually coincides with the location of the boiler, stove or gas water heater.

According to the compiled estimate, it is necessary purchase equipment and consumables... After that, payment is made to the company that will install the device.

Devices without thermocontrollerlocated outdoors or in an unheated room must be hidden in a special box that protects them from external influences.

Exist rules for installing a meter in an apartment:

• the device should be located at a distance of 3 - 5 cm from the wall;
• from the stove or boiler, the meter is mounted at a distance of 0.8 to 1 m;
• placement height - 1.6 m from the floor.

It is not advisable to hide the counter in furniture - it should be in a conspicuous place.

Sealing

After installation and start-up of the system, sealing the meter, and also an act of completed work is drawn up, which indicates data about the device and the master who carried out the installation.

To seal the meter, you must buy a seal and apply to the gas industry... Within 5 days, an inspector comes, checks the correct installation and location of the device, then puts a seal.

In case of failure to perform such actions, the device is considered illegally installed and its readings are not accepted.

Documentation

After completing the registration of the meter, its owner is obliged visit a homeowners association (HOA) and give them one copy of the gas meter commissioning certificate. On the basis of this document, a contract for the supply of natural gas is drawn up, receipts for which will be received every month.

The meter owner must have technical certificate, the first entry into which is made immediately after the commissioning of the device.

Counter replacement rules

Each measuring device has its own permissible service life, after which the unit should be replaced with a new one. Otherwise, his readings are not taken into account, and all calculations will be made at average prices.

Buying a new device, replacing a gas meter and paying for services in full falls on the shoulders of homeowners.

Before replacing the counter, you must write application to the gas industry... After the master comes for measurements, and it becomes clear which device needs to be installed, you can go to the store and buy equipment.

After the replacement procedure, the algorithm of actions is the same as for the first time - checking, sealing, act of completion, issuing a technical passport.

Checking gas meters

Gas meter verification is a set of measures to determine compliance of the device with metrological requirements... Verification beneficial primarily to the owner of the meter, since its readings may differ from the real ones in the direction of increasing the gas volume indicators.

Verification is carried out, if a:

• the stamp on the meter is damaged, and it does not impede access to the internal parts of the device;
• a shock effect on the device was recorded, after which the owner is not sure of the correctness of its readings;
• the unit has been in storage for a long time (more than one calibration interval);
• incorrect operation of the device is assumed.

The subscriber is obliged to perform the next verification before the end of the verification period or replace the meter with a new one.

Difference between verification and verification

If we compare two concepts - verification and verification, then the first term refers exclusively to the metrological properties of the device, its ability to perform its functions. Verification is a broader actionwhich can be carried out:

• in order to study the operation of devices of any type;
• legal assessment of the actions of meter owners;
• research of technical parameters of the device.

Verification is a more targeted study of the operation of the device for compliance with its functionality.

Verification frequency

The frequency of verification depends on the type of measuring device and indicated in the technical passport... Usually the interval is from 5 to 8 years old, sometimes more - from 10 to 12if the quality of the device is initially high. The manufacturer of the measuring device independently determines the need for verification and its frequency.

Ask a Question

An unscheduled calibration of gas meters can be carried out both on the initiative of the owner himself and on the recommendation of the gas company. A household gas meter should be assessed from the point of view of the possibility of its further operation, if doubts arose as to the quality of its work.

Application submission, required documents

You can submit an application for the verification procedure at several companies:

• a special laboratory from a gas company;
• single window service;
• order a specialist in special licensed services.

You can apply on the website of the gas company that is the gas supplier.

How does the verification take place and how long does it take?

In order for the master to make a mark on the verification, it is necessary to find counter passport... This document is also required if a complete replacement of the meter is planned.

If the device is removed and sent for verification, gas is calculated according to average values ​​for the last 3 months... The meter functionality is determined on a first come, first served basis - usually within a month, it undergoes full control and can be installed back if no problems are found.

Ask an expert

How not to run into scammers?

It is best to apply for metrological control to a company with which a gas supply agreement has been concluded. Other companies, private, do not always have the appropriate permits for work, so their marks in the passport can be challenged by licensed specialists.

What will happen if you do not let a specialist into the house?

The owner of the property and real estate on the territory of which the meter is located has the right not to let the specialist into the apartment or private house. In this case, if the verification period is violated, the meter readings from this apartment will not be accepted for payment. Instead, the calculation is carried out at a higher tariff - this is a kind of penalty.

Send the meter for verification or replace it with a new one?

It depends on the quality of the device itself. The service life of the gas meter plays a role, as well as possible shock loading or visible breakdowns that occur.In this case, it is better to replace the meter with a new one so as not to overpay for the energy carrier.
