The easiest mineral to use is gas. This blue fuel is used in our homes for cooking, water heating, heating. The consumption control in the apartment is carried out by a household gas meter, which by its design can be electronic or mechanical. There are several main methods of control on the basis of which these measuring instruments. They are used in everyday life, municipal, industrial enterprises. Their models are designed for different flow rates, pipe diameters.

What is a gas meter

The device for controlling the consumption of blue fuel is called a gas meter. It is included in the gas main (pipe) supplying the house or apartment outside the room or inside it. Using different methods determining the speed of a gaseous substance passing through it, it determines the volume of gas consumed. This value, converted to Cubic Meters, we see on the instrument panel. Liquid-crystal displays are used in electronic flow meters, in mechanical ones - a mechanical counter, which has red divisions showing fractional parts of a cubic meter.

How it works

The gas flow meter consists of three main parts: a sealed housing, a measuring transducer, and a counting device. The measuring mechanism is the main element, and the principle of converting the flow into a mechanical or electrical effect on the counting device determines the type of device. Mechanical converters use different properties gases to move the lever acting on the counting device. Electronic sensors convert the properties of the flow into an electrical impulse that increases the readings on the scoreboard.

Principle of operation

The transmitter uses physical properties flow of a gaseous substance. According to the principle of its operation, there are several types of counters:

Membrane or diaphragm - alternately fills two measuring chambers separated by a membrane. Each chamber has a fixed volume. The inlet and outlet valves are asymmetrically synchronized and alternately let in and out the gas. The movements of the membrane are converted by the lever into a rotation of the drive of the counting device, which shows the volume of fuel that has passed through the device.
Rotary gas meter - uses gas pressure in special tanks to drive two figure-of-eight shafts (rotors), one of which is connected to a counting mechanism drive. The counter converts the number of revolutions into the amount of fuel. The advantage is that it works at low pressure.
The turbine principle is based on measuring the flow velocity by counting the number of revolutions of the turbines that rotate under the pressure of the flow. Such metering devices are used only at public utilities and industrial enterprises for metering large volumes.
The vortex flow meter uses the dependence of the frequency of pressure fluctuations that occur after the jet of a gaseous substance is given a vortex shape. The mechanism for accounting for these fluctuations is complex, requires the use of complex microprocessor technology, so such devices are expensive and are used only at large gas distribution enterprises.

Types of gas meters

The main characteristic that separates gas flow meters into two types is their throughput or the volume of gas that can pass through the counting device in 1 hour. According to this indicator, they are divided into:

Household - this is the most common type with a throughput of up to 12 cubic meters / h. They use a membrane, diaphragm and rotational measurement principle.
Industrial - all flow meters with a throughput above 12 cubic meters per hour. Up to a value of 200 cubic meters / h, rotary converters are mainly used, above this indicator - turbine, vortex.

When purchasing a gas meter, you need to clearly understand how much you will consume - the type of device you need and its price depend on it. Gas distribution companies in different cities recommend the use of certain models. This is due to the well-established system of verification and repair of such devices at these enterprises, the availability of spare parts, and the qualifications of personnel. Therefore, it is worth asking the gas service where to buy a gas meter, acceptable models and brands gas equipment.

You can buy household gas meters in hardware stores or building supermarkets in Moscow, St. Petersburg, and other Russian cities. For active Internet users, you can find out how much a gas meter costs in numerous online stores. Without leaving your home, it will be easy to choose a model from the photo, and then order. On promotions, on sales, with discounts, make a purchase more profitable. Delivery of all goods is carried out by courier services or cheaper - by mail.

How to choose a gas meter

The main input data when choosing a gas meter are:

throughput. It must be higher than the gas consumption of all consumer devices. Household four-burner stoves, gas water heaters consume no more than 2.5 cubic meters / h, so a meter with a capacity of more than 5 cubic meters is suitable for an apartment with a stove and a water heater. m/h
Direction of flow in a pipe. This indicator must correspond to the flow direction of the metering device. It is advisable to purchase devices with an electronic corrector - a device that takes into account temperature and other atmospheric effects on measurement accuracy.
Gas meter price, installation costs.
General term operation. good options- with a period of 15-20 years.
Intertest period. Best Samples household appliances have this indicator for at least 10 years.

For a private house

It is especially necessary to carefully consider the purchase when choosing a gas meter for a private house. The main unit will be a gas heating boiler. It is necessary to take into account its maximum consumption in the coldest periods. To this value must be added the consumption of a water heating device, a gas stove. The nominal value of the flow meter should be 30-50% higher than the sum of all consumers. An important point is the installation location of the flowmeter. If it is necessary to place it on the street, street models with a filter and a thermal corrector are required.

To the apartment

When choosing a gas meter for an apartment, decide on your peak gas consumption. If you have central heating, there will be less consumption for the volume of consumption of the heating boiler. Devices that work with noise are best placed in the pantry, compact electronic flow meters are suitable for the kitchen. An electronic meter is more accurate, but also more expensive. If you want to save money, choose mechanical flow meters. The lower the cost of a gas meter for an apartment, the greater the measurement error they allow, for which you will have to overpay.

High price utilities- perhaps one of the most important problems of people. Moreover, many quite rightly believe that they significantly overpay for resources. The installation of metering devices helps to solve the problem. A gas meter is one such device that will help you significantly reduce costs, because its purchase and installation will pay off in a few months. Let's try to understand the varieties of devices, and also decide which of the metering devices is better. Consider gas meters in an apartment - how to choose, by what criteria?

Classification

To know how to choose gas meters for an apartment, we will classify apartment devices, starting from the principle of operation.

Membrane:

This is a simple and reliable design.
Membrane gas meters are relatively inexpensive, but have significant dimensions.
This design is produced by both domestic and foreign companies.
The device is absolutely safe and durable. Its working resource is about 30 years.

The principle of operation is simple. The gas flow causes the diaphragm to move. The counting mechanism takes into account the amount of gas you use.

Important! The disadvantage of membrane meters is that if it is necessary to measure large volumes of gas, it can give inaccurate readings.

Rotary:

The frequency of verification of such metering devices is at least once every 5 years.
These devices operate almost silently.

These are important advantages.

The main detail of such a device is two rotors, which form a kind of "eight" between them. The account of the consumed gas is made on the movement of rotors.

Important! The downside is the low accuracy. Not a very pleasant feature is that it is not reliable enough and fails more often than others.

Electronic:

This is the most accurate gas meter.
The device is compact, modern design works completely silently.
The frequency of verification is much less frequent compared to rotary ones - once every 10-12 years.
The meters are suitable for installation both in residential premises and in industrial enterprises.

Important! They have one drawback - a relatively high cost.

Conclusion

If your gas consumption is limited to a column or stove, then the best gas meter for an apartment will be a rotary type or electronic device.

How to choose a gas meter for a private house?

When choosing a gas meter for an apartment, the following factors are taken into account.

Dimensions of the device, the place of its installation.
Price.
Noise at work.
The length of the period between two verifications.
The value of the marginal norms of gas consumption.

Other features:

The choice of a meter also depends on external conditions - ideal if the operating temperature range is from -20 to +60 degrees.
If the machine is too noisy and (or) large, it is advisable to install it in the pantry. More compact option - for the kitchen.
Given the need to periodically check the device, it is necessary that access to it be free.

Important! When planning the purchase budget, deciding which gas meter is better to put in the house, consider the installation costs. It is advisable to entrust the installation of a gas meter in an apartment to specialists.

Overview of manufacturing companies

Russian companies produce devices that the best way fit the conditions of gas consumption in the countries of the former USSR. Here is a rating of gas meters for an apartment.

Betar:

Counters from this company are often used for apartments with a gas stove.
The gas pipeline can be either vertical or horizontal.
The period between two verifications is 12 years.

Gazdevice^

Gazstroyneft:

The company manufactures jet devices for gas metering in an apartment.
The minimum operating life of the device is 12 years.

Important! Popular products and such trademarks as “Appliance”, “Vector”, or “Signal”.

Installation Features

It turns out that buying a metering device in an apartment is not all. How to install a gas meter in an apartment?

The first step is to submit an application to the gas supply service for the installation of a meter. Further - technical requirements. The minimum height of the device is 1.6 m. At the same time, it is necessary to leave a gap of 3 cm between the wall and the fixture. This will reduce the risk of corrosion of the device.
It is also necessary to ensure that the meter is installed in a well-ventilated area, in no case near water or heating equipment.
Before installation, you need to take care of the dust filter, without which the device will not work properly.
After installing the meter, the master will make a note in the technical passport for the device. Alternatively, you can contact the gas service to register the device.
The next step is sealing the gas meter.

Important! In addition, such documents must be signed.

To date, gas heating is one of the few alternatives to meet the needs of a private home. It is much more profitable to receive heat from gas boiler than heating water with electricity. When connected to a gas main, the owners need to take into account the incoming gas. To do this, a metering device is placed on the incoming pipe. However, before choosing a gas meter for a private house, it is worth considering in more detail its characteristics and technical indicators.

What to look out for

To select the optimal device, you should pay attention to:

throughput of the device. In this case, we are talking about the ability of the device to pass a certain amount of fuel in a given unit of time. If only the stove consumes gas in the house or hob, the device is enough for 1.6 m3 / h. When it's in the house geyser, choose a device with a throughput of at least 2.5 m3 / h. If there is a heating boiler in the house, they put a counter up to 4 m3 / h.
When the house has all three fuel consumers at the same time, put the device up to 6 m3 / h.
Inlet pipe diameter, which is connected to the counter. It is usually ½ or ¾ inch. Less common are pipes with a cross section of 1 inch. Depending on the diameter of the pipe, union nuts for the counter are selected.
Center distance. This parameter is relevant for the "upper" installation on the main gas pipeline. This type of installation is more often used in private homes, so it is worth considering this option in more detail.
There are three distances between the fittings of the counter: 250 mm, 200 mm and 110 mm. Greater distance corresponds to greater gas consumption. For example, for a house with three consumers, a device is installed with a fitting distance from 200 mm to 250 mm. It is also necessary to take into account the direction of gas supply relative to consumer devices. Usually it is indicated by a special arrow on the counter itself.
Temperature mode of the device. When choosing a meter, be sure to pay attention to the conditions of its operation. If the counter is at outdoors in an unheated room, choose a device with a temperature regime of +40 to -40 Cº.
Gas meter reconciliation interval. Each gas meter model has its own verification interval. It is responsible for the period of time that indicates the maximum service life until the next check of the device.

Choosing a gas meter

How to choose a gas meter for the home so that it lasts a long time and does not take much effort during installation, we will consider below.

When choosing a gas meter, you need to take into account some parameters of the device itself:

When choosing a meter, take into account the direction of gas movement in the pipe. There are devices where gas flows to the right or left along the main fuel line. It is worth noting in advance the movement of gas through the main pipe and the location of the consuming devices in the house.
Before buying a gas meter, measure the distance at the attachment point from the center of the pipe to the wall of the device. When choosing a device, this distance must be greater than the segment between the axis of the connecting pipe and the rear wall of the meter. Otherwise, the device may simply not fit in its dimensions.
If the gas pipeline is already installed, be sure to measure the axial distance between the pipes. According to this parameter, a metering device is selected. Otherwise, you will have to change the entire system or buy a new meter.

The meter is selected depending on the volume of gas consumed. To do this, all fuel consumers in the house are counted.

Gas equipment masters usually advise installing two types of devices:

mechanical;
electronic.

The first devices are more reliable and low cost. However, they are not used for negative temperatures and produce large quantity noise. Such devices can be installed in a warm utility room.

The electronic meter is not afraid of cold and can be mounted both outdoors and indoors. It is silent and compact. At the same time, it has greater accuracy and can be serviced using special diagnostic equipment.

Professionals note that the service life of the device is counted from the date the device was released, and not from the moment it was installed.

When choosing a gas meter for a private house, all indicators must be taken into account. Installation of the device should be entrusted to professionals. It is worth remembering that incorrect or inaccurate installation of the device can lead to disaster.

To decide which gas meter is better to install, you need to know where it should be installed - in an apartment, in a private house (cottage, cottage) or on the street. There are many varieties of them (membrane, electric, rotary, volumetric). The cost ranges (roughly) from $30 to $300 or more.

Gas meter for an apartment

Here they are used for installation without a thermal corrector. Membrane, electronic and rotary counters are used. Their advantages and disadvantages can be seen in the technical descriptions.
To choose a particular brand, you need to solve the following questions:
- maximum volume of consumed gas;
- place of installation of the counter;
- frequency of verification;
- reliability and price.
If the apartment is equipped with a gas stove and water heater, then it is better to install an electronic or rotary counter.
If an individual heating system is used, then either a volumetric, or a rotary or electronic meter can be installed.

Gas meter for home (cottage, cottage)

To select, you need to determine:
- the total number of consumers and the maximum volume of gas consumed;
- place of installation of the counter;
- the presence of a thermal corrector;
- compactness and noise level;
- frequency of verification;
- reliability and price.
When using an individual heating system, you can use both volumetric and rotary or electronic meters.
If in a private house (cottage, cottage) there is only a gas stove or water heater, then the right decision would be to use an electronic or rotary meter.

Outdoor gas meter

Here you need:
- calculate the total number of consumers and the maximum volume of gas consumed;
- the presence of a thermal corrector (the cost of gas will be changed);
- take account temperature regime, (V winter time the outside air temperature can reach -30 degrees C or more, which will affect the instrument's error);
- installation of the counter in the open air or in a protective case (rotary, volumetric and electronic counters can be used outdoors).

Choice between mechanical and electronic counter

A mechanical gas meter is low cost, simple in design and reliable, but noisy.
The electronic meter is used both indoors and outdoors. It features high measurement accuracy, quiet operation and small dimensions. Works stably at low temperatures. It is possible to connect equipment for diagnostics and transmission of information to digital. The price is higher than that of a mechanical meter.
Considering all the factors that are outlined here, everyone decides for himself which gas meter to choose. Be sure to coordinate this issue with the specialists of the gas service.

Today, almost all private houses are heated by gas, but they can also be found in urban high-rise buildings. And in order to monitor the volume of gas used, special gas meters are used. In this article, we will find out what counters are in general, what are the strengths and weak sides each type, and which gas meter is better to put in an apartment.

Interesting information! Did you know that the first screwdriver appeared in the 17th century? For more details on the history of this useful tool, see.

Electronic. Their distinguishing feature is high accuracy of readings, almost complete noiselessness and ease of settings. Checking should be done every 11-12 years. These cost about 30-170 dollars, they are made both for industry and for domestic use.
Rotary. They are small, but inexpensive and produce little noise. Disadvantages - the error and the need for verification every 5 years. Will cost about 25-100 dollars.
Volumetric. Characterized by excellent throughput, durability and affordable price. Checked every 10 years. Minuses - high level noise, volume. They cost about 25-120 dollars.
Membrane. Reliable, simple and inexpensive devices. The average cost of such equipment ranges from 20-100 US dollars. Its disadvantages include the need for frequent checks, overall dimensions and high noise output.

Gas meter in the apartment - choose the right one

To date, only those gas meters that do not have thermal correctors are used in city apartments. In most cases, these are rotary or electronic devices, although membrane-type devices are not uncommon. We have considered all the good and bad that is in each of the options, and now we will find out which one is better to use in the apartment.

But before proceeding with the choice of one or another of the presented options, it is necessary to take into account the following points:

Where will the meter be installed?
its cost;
compactness;
reliability;
noise performance;
required inspection frequency;
limiting volumes of consumed gas.

So what kind of device to choose for your city apartment?

When it comes to an individual system gas heating, then you can safely purchase a volumetric, electric or rotary type device.
And if the dwelling has only a gas column or stove, then the best option there will be a rotary or electronic type device.

That's all, we got acquainted with the features of choosing a counter. In conclusion - a thematic video about the installation of a gas meter.
