Types of gas meters

The gas meter is represented by different types (rotary, membrane-diaphragm, vortex and drum) and standard sizes, depending on its throughput. The standard size of a household meter depends on the number and type of gas equipment in the house:

Membrane, which is sometimes called chamber or diaphragm.

The metering device consists of a body, covers, measuring mechanism, counting mechanism, crank-lever mechanism and gas distribution device.

The principle of operation of this meter is based on the fact that the gas is divided by the moving parts of the device into fractions of the total volume and then cyclically summed up.

In a turbine gas meter, the volume of gas consumed is calculated from the number of revolutions of the turbine caused by the incoming gas.

The counting mechanism is located outside the gas cavity and takes into account the number of revolutions passing through the reduction gear and the gas-tight magnetic coupling. Under operating conditions, the device takes into account the total volume of gas in increments.

The device clearly captures the gas flow rate and when attempting external unauthorized intervention
The contacts will simply close and the meter will not work.

A turbine gas meter looks like a pipe section with flanges, on which a rectifier and a turbine assembly are installed in the flow part. An oil unit is also installed on the instrument case, which is necessary for lubricating the bearings of the turbine mechanisms. Also, temperature, pressure and pulse sensors can be installed on the turbine housing.

Turbine metering devices are divided into three types, differing among themselves in varying degrees of automation and information processing:

• For separate parameter measurements
• For semi-automatic parameter measurements
• For fully automatic measurements of all parameters
• Depending on the budget and the desired result, you can choose exactly the gas meter that is suitable in this particular situation.

Rotary meters

There are more and more types of gas metering devices and the emergence of rotary meters on the market as optimal metering devices for gas volumes in the utility sector.

It has a large bandwidth and has a wide range of different measurements. With such characteristics, the small size of the device is surprising. A rotary gas meter does not need electricity, is known for its durability and the possibility of additional monitoring of the correct operation of the gas pressure drops in the pipe. At the same time, this meter is not sensitive to short-term overloads.

The gas entering the body of the rotary meter rotates two figure-of-eight rotors of the same size.The inlet and outlet parts of the device are nozzles, rotating rotors are constantly lubricated with oil, to ensure accurate trouble-free operation. By reducing friction and minimizing gas leaks, the instrument shows all data as accurately as possible

Therefore, special attention is paid to balancing and processing of rotors.

Vortex gas meters

This meter is considered the most accurate, since the readings do not depend on pressure and temperature. True, at a low gas flow rate and the need to work in an aggressive environment, these meters are not recommended, since the measurement error increases.

The operation of the device is based on the dependence of the flow rate on the frequency of pressure fluctuations, which occurs during the formation of vortices.

The design of the device provides for a truncated prism, which flows around the gas flow. Behind the prism is a highly sensitive element that captures the vortices.

Liquid gas meters.

No less accurate than vortex are liquid gas meters. It is believed that their readings are even better than vortex ones. But the downside for customers is both the complexity of the design of the device itself and the difficulties in maintenance.

Most often, such devices can be found in laboratories where they are used at a professional level.

The principle of operation of the device is to take into account the speed of expulsion of gas in certain portions from a certain liquid. Most often, the process occurs on the basis of distilled water.

About the need to periodically check the gas meter

Any metering device should be periodically checked for defects. This may be a visual inspection by the user. The following symptoms can be considered a malfunction:

• the integrity of the control seals is broken;
• the device does not show the results of counting cubes;
• displays indicators with a large error;
• there are traces of mechanical damage to the device.

   
Verification involves the removal of the meter, diagnostics and the issuance of an appropriate act.

Having discovered one of the defects, the user must, as soon as possible, contact the organization that monitors the supply of gas to the consumer and ensure that the malfunction is eliminated within 30 calendar days.

In addition to the owner, the check of the meter must be carried out by employees of the gas organization with which the owner has entered into an agreement on the maintenance of gas equipment. Regardless of the manufacturer and cost of the gas meter, the level of its improvement, each device has a passport, which specifies the frequency of its verification. It involves the removal of the meter, diagnostics and the issuance of an act that allows or prohibits further operation of the device.

Note! In the absence of results of timely verification of the meter, the device is considered unsuitable for operation, and the readings are invalid.

In addition to verification, employees of the organization that control the operation of gas equipment are required to check once every six months without removing the device. According to its results, an appropriate act should be drawn up.

Periodic verification of the gas meter is carried out to determine the suitability of the meter for reliable gas metering.

Responsibilities of the meter owner

Important! According to the legislation of the Russian Federation, the owner is obliged to fulfill:

• the owner is obliged to purchase the necessary device and provide equipment for installation before starting work;
• the owner must maintain the equipment, maintain the integrity and ensure that the device is fully functional;
• if there is a division of duties between the company installing the measuring equipment and the owner in the contract, all duties and their division occur in accordance with the instructions in the contract;
• the owner has the right to conclude an agreement on the provision of maintenance with the state, this will deprive him of obligations and liability in some cases related to the performance of the measuring equipment;
• when renting the premises, the owner is responsible for the integrity, serviceability and conscientious attitude to the equipment, even in cases where the state is the tenant.

Verification interval

This is the time during which the manufacturer guarantees that the device will work correctly. Usually this time is eight to ten years.

During operation, the gas meter is influenced by various factors, which usually negatively affect its further condition. This may be the effect of temperature, moisture, or simply the aging of the materials inside the device. Due to these changes, the exact operation of the device may change. And what to do if the gas meter verification period expires? Then you will pay a fine for the delay in verification and still call the master to check the equipment.

Verification is carried out by the gas service. The whole process can be divided into several stages:

First you need to call an employee of the gas service, with which an agreement was concluded on the maintenance of gas equipment.
Dismantling the device. This procedure will be carried out by a gas service worker.
Verification of its performance and accuracy in a special service. It usually takes about two weeks

It is important that at this time the calculation of the cost of gas will be based on the area of ​​​​the apartment.
Verification result.If your device meets all standards, then it will be returned and sealed, the date of verification will be noted

If the meter is found unsuitable for further use, you will be informed about this, and a document will be issued on the device about the impossibility of use.

If the verification was not carried out on time, then the readings of this device will not be taken into account in any way when presenting the gas bill for payment.

An important aspect in choosing a gas consumption measurement device will be the number of devices in your home.

Typically, counters cost from 1,400 rubles to 20,000 rubles. The price depends on the calibration period and the country in which the device was manufactured.

Only those meters that have passed all verifications are installed. This is evidenced by the seal on the body. Why is verification needed?

The cost of a gas meter for a private house

Before installing a meter, each consumer asks himself how much a gas meter costs for a private house. To get an answer, just looking at the digital values ​​of prices in the catalogs of trading companies will not be enough. It is necessary to understand the principle of operation of accounting devices, compare various options, get acquainted with the opinions of experienced users, and only after that 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 membrane models of domestic production with a mechanical method of counting and a nominal throughput of up to 6 m3 / h.

For example, a VK G4 gas meter costs 2200 rubles; the VK G4T device has a price of 3400 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 the 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 a private house

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

It is to such devices that Grand counters should be attributed. They may have different throughput. The salient features of these devices are:

• small sizes;
• energy independence;
• simple installation;
• resistance to temperatures and pollution;
• accuracy of indications;
• long warranty period (12 years).

Popular with consumers are those models that have proven themselves well.

Electronic meters "Grand" very rarely fail. They can be mounted both vertically and horizontally.

One of the best gas meters for a private house are also Betar gas meters. Models have a fairly high technical level, many are supplemented with a heat correction function. Devices are small-sized, can be installed both in a vertical and in a horizontal plane. Among the model range are devices with remote control, which can be connected to the autonomous Smart Home system.

Gas meter: which one is better for a private house

When choosing a gas meter for a private house, the following indicators must be considered:

• the number of units of gas equipment;
• family composition;
• location of the meter.

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

The amount of gas used depends on the number of consumers and the types of installed gas appliances. Under the conditions of placing only a column and a gas stove in the house, a meter with a capacity of up to 2.5 m3 / h is quite enough. 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 house, you need to determine its location. With external hanging, the influence of temperatures increases, the range should be -40 - +50 ° С. Therefore, it is necessary to carefully study the passport data before purchasing the device.

An important option for a gas meter for street placement is thermoregulation. The built-in function eliminates the need to use an additional coefficient when calculating payment

Power supply of a smart meter

Smart flowmeters, like simple electronic ones, are completely autonomous - they do not require the use of additional mains power. The autonomy of the devices is provided by a pair of batteries - batteries.

In particular, the main energy element is the Li-SOC12 (lithium-thionyl chloride) battery, while the spare battery is Li-MnO₂ (lithium manganese oxide).

The main energy source of a smart gas meter is a battery cell based on lithium-thionyl chloride (Li-SOC12). Provides ten years of smart meter performance

The main battery provides 3.6 volts and is a removable and fully replaceable component.The second (backup) battery is hard-wired into the electronic board, and therefore does not provide for interchangeability.

This 3 volt power supply is connected to the system when the main battery is replaced, which ensures the safety of the technological parameters of the device.

According to the manufacturer's specification, the main power supply is enough to operate the meter for up to 10 years. Therefore, battery replacement, as a rule, coincides with the instrument verification procedure, which is usually carried out every 5-6 years. The performance of the backup battery, in the absence of the main battery, is guaranteed for 1 year.

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 service life. Good options - with a period of 15-20 years.
• Intertest period. The best samples of 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 flowmeter 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.

Instrument selection criteria

Throughput is the main characteristic by which you need to choose a gas meter. It shows how much gas can pass through the meter in 1 hour of operation.

To determine the required throughput, you need to add up the gas consumption of all devices, thereby you can find out the maximum amount of gas consumed and select a meter with a margin. In private homes, gas consumption ranges from 4 cubic meters. m/h up to 10 cu. m/h To simplify the selection of the counter, a special marking has been introduced:

• G1.6 - throughput 1.6 - 2.5 cubic meters. m/h;
• G2.5 - throughput 2.5 - 4.0 cu. m/h;
• G4 - throughput 4-6 cubic meters. m/h;
• G6 - throughput 6-10 cubic meters. m/h;
• G10 - throughput 10-16 cubic meters. m/h

G1.6 and G2.5 are practically not used in private homes due to their low power. G10 is also rare, but already because of its redundancy. The most common gas meter for a private house is G4 or G6, they are optimal for calculating gas consumption for an average house.

Also, the meters differ in their design, in the private sector it is permissible to use three types of metering devices:

• Electronic - accurate, compact, modern metering devices. Insensitive to external temperature changes. The disadvantages include their high price and power from the built-in battery, which can stop working long before the expiration of the verification period, which is 10-12 years. An electronic gas meter can be used in a private house with moderate gas consumption.
• Rotary - compact devices with high throughput and prefer to work at a constant gas flow. But installation is allowed only on a vertical pipe and the verification period is only about 5 years.
• Membrane - noisy, but simple and high-quality metering devices. Leader for installation in the private sector. The service life of the device is 20 - 30 years. Verification must be done every 10 years. All the inconveniences associated with large dimensions and high noise levels are offset by their ability to be installed outdoors.

If the meter will be installed outside the house, then it is better to buy a device with a thermal correction function.Despite the fact that a standard meter is capable of operating at temperatures from -40 to +40, the accuracy of measurements at critical temperatures leaves much to be desired.

The counter shows exact data at a temperature of about +20 degrees. Depending on the temperature, the gas can contract or expand. Therefore, in winter, the meter will give readings less than actually spent.

In the summer, on the contrary, the numbers on the counter will be larger. In addition, if a meter without thermal correction is installed on the street, then the owner of the house will have to pay an additional temperature coefficient.

Features of installation of gas flow meters

Only authorized representatives of the service company should carry out work on gas equipment. However, a few rules will not hurt the future owners of gas meters to know.

1. Fuel temperature. The permitted temperature range is quite wide: from -20 to +60°. However, limit values, or those close to them, are still not recommended. For this reason, outdoor equipment may require good thermal insulation.
2. Outdoor flow meters are recommended to be installed at a distance of 1.6 m from the ground. There are no such restrictions for a house or apartment, since everything is decided only by where the branch from the common riser is located.
3. The distance from the gas meter to any heater should be 0.8-1 m, at least. Otherwise, the performance of the flowmeter will be affected.

Good ventilation of the room is a must. In the same way as water meters, gas appliances must be sealed before operation.

The owners decide which gas meter to buy, since much, if not all, depends on the specific conditions.The following video, perhaps, will prompt the answer if the favorite has not yet been found by the future owners:

How to install a gas meter on your own

Immediately make a reservation that such counters are representatives of the category of devices of increased danger. Therefore, their installation must be carried out exclusively by professionals who have passed the appropriate certification. Simply put, we have a lot of smart people, but this does not mean that your friend or you yourself can install the counter (if there are no powers for this).

Note! Another important point: the specialist must be an employee of the same company that provides you with gas. Otherwise, the device will not be registered, because

e. it will not be registered.

The installation of a gas meter in the apartment itself should be carried out according to the following algorithm.

Stage 1. We turn to the help desk of the company that provides us with energy. To do this, we need at least their contact number, which can be found on the back of the payment receipt (it should come every month). We communicate with a specialist and find out exactly which address you should contact with the submission of the corresponding application. We can also inquire which office to go to.

Stage 2. We come to the specified address to the gas service in order to write an application for installing a meter. We take with us the following list of documents:

• Russian passport;
• a receipt that gas bills (for the past month) have been paid;
• certificate of ownership of the apartment (as an option, a lease agreement is also suitable).

If the housing has several owners at once, then each of them has the right to write such a statement.The employee who accepted the application informs us when a specialist will come to us for preliminary measurements.

Stage 3. We carefully consider the place where the device will be installed. At the same time, do not forget that the meter should be located no further than 0.8 meters from the consuming device (gas column, stove). The installation height is also normalized - it is at least 1.2 meters. There are no other requirements, so we focus more on ease of use. Sometimes specialists who take measurements determine the place themselves and say, they say, the device will be installed here. But this is only his personal opinion, which, of course, may not coincide with ours. Remember: we have the right to independently choose the place of installation, but in such a way that the key rules are not violated.

Of course, the greater the length of the pipeline before and after the device, the greater the amount will have to be paid for the installation and consumables. Although all this can be discussed directly with the master when he comes for measurements.

Stage 4. On the appointed day, we again come to the gas service, pay the cost of the project, as well as installation work. We discuss with the master the date and time when the company's repair staff will come to us. Everything else should be done exclusively by professionals.

Note! If you wish, you can purchase a meter yourself, if, for example, we learned that it costs less than that of a gas service. But in this case, you must first find out what parameters this device should have.
