How to choose a gas meter: guidelines for choosing a device for a private house and apartment

Which water meter is better to choose?

Water meters allow you to accurately record the consumed cubic meters of water. Thus, payment for water will be carried out not according to average standards, but according to real consumption.It remains only to determine which one is still better to install a water meter, and then choose a company that provides installation services for the water metering system.

If you want to install a really high-quality counter, it is important to understand how they work. It is necessary to understand the basic schemes of the operation of counters

They are:

• mechanical;
• electromagnetic;
• impulse;
• turbine.

Mechanical water meters are characterized by extremely low error, as well as small dimensions. Such devices can be divided into vane and turbine ones, they differ in the position of the blade of the rotating mechanism in relation to the water flow. Mechanical type water meters can also be divided into single-jet and multi-jet, the latter are considered more accurate.

Electromagnetic meters are used in light and heavy industries, they are excellent for measuring any volume of electrically conductive liquid. They are distinguished by a wide measurement range and the absence of moving parts, and therefore are reliable and, with timely maintenance, can carry out trouble-free operation for many years.

Pulse meters are often called dry-running meters, since their moving mechanism does not come into contact with water. The competitive advantage of this solution is the ability to transmit information to the management company remotely using impulses.

It is better to install such water meters in rental houses and apartments where there is no permanent access to the bathroom to take readings on the spent cubic meters of water.

We are least of all interested in turbine water metering systems, since they are used for pipelines of really large diameters.

Want to install a water meter? Be sure to take into account the diameter of the water meter and the method of its possible installation, throughput, as well as the diameter of the pipe. Vane meters are installed strictly in the cut of the pipeline, the work must be carried out by really qualified plumbers, since welding is required

Vane meters are installed strictly in the pipeline section, the work must be carried out by really qualified plumbers, since welding is required.

Multi-jet products are installed in apartments and offices, as the installation is carried out using fittings that are already supplied with the water meter. Do not require the use of a welding machine and valve meters, which are installed in place of the stopcock.

What water meters are better to install for an ordinary residential apartment? In the plumbing fixtures market, you can find a large number of manufacturers, including those from China. Do not choose Chinese water meters - their mechanics are too fragile, products will hardly last more than 2-3 years.

The difference between such devices lies mainly in the materials of bearings and impellers. If you are in doubt about which water meter to purchase, then you need to contact the experts.

Selection and purchase procedure

Before you buy a device, invite an employee of a gas organization to your home, who will inspect the structure of the gas supply system, calculate the required throughput and tell you what characteristics it is worth buying a meter with.

It is worth buying equipment only in reliable stores that sell quality products and give a guarantee. Do not take products in the markets and in dubious outlets.There is no certainty that you will not be sold a fake.

You can also purchase a meter via the Internet - on the manufacturer's website or trading platforms. In this case, the goods will be sent to you by mail, courier or handed over to a specialized pick-up point.

Each device must have a passport, which indicates the date of the first verification.

Several installation rules

When installing gas meters, several rules must be observed. Installation must be carried out at a distance of at least one and a half meters above the floor and no closer than five centimeters from the wall. The generally accepted distance to the serviced units is about eighty centimeters. Meters should not be located in damp and warm places, near heating devices. The room must be well ventilated.

Among the variety of products, the gas meter SGMN 1 deserves attention. Consider what is the advantage of the device and what are its features

How to take readings

Reading of indications for subsequent reporting should be carried out taking into account the following features. Part of the instrument's digital scale has a white background and a red background (red rectangle).

The controlling organization is only interested in the values ​​of the first five digits (green rectangle). The readings submitted for verification indicate the number of cubic meters of gas consumed during the reporting period. Based on these data, the amount due is calculated.

It must be remembered that the readings depend on the ambient temperature. If it is installed outdoors, temperature coefficients must be taken into account. Each region has its own values. For example, for the Central Federal District they are set at 0.95-0.97 in summer, and in winter it reaches 1.14-1.16. Sequence of taking readings:

1. Calculate the readings of the left side of the sensor (mechanical or electronic);
2. Multiply the obtained data by the temperature coefficient depending on the season.
3. Enter the obtained data in the reporting document.

We recommend: Gas meter SGBM 3.2 - description and characteristics

To determine the spent cubes for the month, it is necessary ("-" is a minus): total cubes = numbers on the scoreboard - numbers on the scoreboard a month ago.

The amount you have to pay: the amount of payment = total cubic meters * for the gas price per cubic meter * for the temperature coefficient (it is not necessary to multiply by the coefficient).

How do gas meters work?

According to the principle of operation, there are 5 types of counters, including:

• membrane;
• rotary;
• tachometric turbine;
• vortex;
• jet.

A person who has never encountered such equipment is unlikely to understand their work without additional information. In order to understand everything, our resource exists.

Membrane meters and what they are

The most reliable and demanded device, especially in private sectors. The principle of operation, to put it simply, is to transfer gas from one tank (there are several of them inside) to another, then a third, etc. When the tank is filled, the membrane is activated, bypassing the gas, and it passes on. The point is that the device takes into account the number of diaphragm operations and, based on this, calculates the consumption. This is already simple if it contains the volume of each of the tanks.

The disadvantage of such devices is their bulkiness, so they try not to install them in apartments. In addition, they are quite noisy during operation.

Rotary metering devices: operating features

These devices are more compact, but they can not be used everywhere. Their installation is allowed only on a vertical pipe and when gas is supplied from top to bottom.

Inside it is a chamber in which there are two blades (they are in the shape of a figure eight), tightly fitted one to the other. With the passage of gas, they begin to rotate, transmitting torque through the gear to the counting mechanism.

The disadvantage of such models is the wear of the mechanism, which determines the short calibration interval - 5 years.

Tachometric turbine counter, its application

Such a device belongs to the industrial. Its work is based on the rotation of the turbine under the influence of the pressure of the passing gas located inside the housing.The main problem of such a device is the rapid drying of rotating components, so a constant supply of oil is necessary here. It is carried out by a specially installed pump.

The design of the device is reliable, unpretentious and easy to maintain, but they have one significant drawback. With intermittent gas supply, as in houses, the error increases, and therefore it is recommended to install them only on lines with constant pressure.

Vortex devices and how they differ

The principle of operation of the devices is to assess the frequencies of oscillations that occur with a vortex-like form of a gas flow. These meters can be called the rarest, their cost is high and they are used more often only at gas distribution substations.

Ultrasonic and jet meters for private houses and apartments

These are the most common metering devices installed in apartments or houses with low gas consumption.

Ultrasonic meters transmit waves through a passing gaseous medium, taking into account the difference in their passage. This is the basis for the calculations and calculation of consumption. The calibration interval is 6 years.

Inkjet devices are quite compact and can be installed both vertically and horizontally. The principle of operation is simple. Through a thin nozzle, gas is supplied to the element, which generates impulses. In this case, the higher the pressure, the more pulses will be sent to the controller. Such counters are equipped with a liquid crystal display, on which readings are displayed.

This design is quite reliable and has a minimum of knots, which increases durability. The calibration interval of inkjet machines reaches 12 years, which often becomes the decisive argument when buying.

Verification

The calibration interval for the SGMN 1 G6 gas meter is eight years. This means that every eight years it is necessary to check the device for the absence of malfunctions or incorrect calculation. It is possible to perform verification directly at the customer's home or in a gas management organization. To do this, the device is dismantled and delivered to specialists. To pass the check and obtain the appropriate document, you must provide a passport to the counter.

With rational and proper operation of the flowmeter, its service life varies within eighteen to twenty years. During this period of time, the verification of the SGMN flowmeter is carried out two or three times. If malfunctions are found, a new meter must be purchased.

Verification

How to choose a gas meter

The meter "does" the calculation of the used natural gas, thereby performing two functions at once. Firstly, it guarantees a fair payment for utilities: the amount received at the end of the month will clearly stem from the amount of resources spent. Secondly, the meter encourages the owners to save gas: it is much more difficult to spend it thoughtlessly, realizing that every “extra” cubic meter will be deducted from the family budget. The expediency of acquiring a meter is beyond doubt - much more questions relate to the features of choosing this device. What characteristics should be taken into account? How to buy a gas meter correctly?

Counter types

According to their design characteristics, different types of devices are distinguished. They differ in appearance, purpose, and cost.

Now on sale there are mechanical and electronic devices. The advantage of the latter is in a more accurate measurement and the absence of errors.

According to the method of fixing the amount of resources expended, there are several main types. We will not describe in detail the technical features of their work, since this does not play a special role for the consumer. Consider only the purpose, the main advantages and disadvantages.

Rotary (rotary)

Most often used in enterprises and boiler rooms.

pros	Minuses
High throughput	If the glass cracks, a gas leak may occur.
small size	Verification will have to be carried out often - once every 2 - 5 years
overload resistant
Average noise level
Affordable price

Membrane (diaphragm)

Suitable for installation in any dwelling, but it is better to put it in a private house.

pros	Minuses
Reliable. Service life 20 - 30 years	Large size: it is difficult to find a place for him in a small kitchen
Rare verification - once every 10 - 15 years	Noisy due to design
Rugged sealed housing protects against leaks
Not afraid of bad quality fuel
Can be installed outdoors
Acceptable cost

Jet

Suitable for any space.

pros	Minuses
Operating period - 20 years	Can become clogged if the incoming mixture contains impurities
Calibration intervals 10 - 15 years	Sensitive to changes in ambient temperature
Accuracy of measurements	High price
Can be mounted both vertically and horizontally
Compact dimensions
Silent

There are also turbine and drum devices, but they are used in industries with a high level of fuel consumption or in laboratories. It makes no sense to consider them, since they are not installed in houses.

It turns out that an electronic inkjet apparatus is best suited for an apartment.Although it is quite expensive, the benefits outweigh the costs.

Bandwidth

The main parameter that the buyer should pay attention to is the throughput of the device. Before purchasing, the owner must determine the maximum gas consumption in the apartment or in the house

It is indicated in the passports for household appliances (gas stove, water heater, etc.). Gas consumption must be summed up. This value will be the main one when buying a counter. This indicator of the gas meter cannot be less than the total.

There are three types of devices available:

• To connect one consumer, devices with a maximum throughput of 2.5 m3 / h are installed. The scoreboard will read G-1.6;
• A meter with the designation G-2.5 is installed when consumers are connected to the main line with a gas flow rate of not more than 4 m3;
• For consumers with high hourly consumption, G-4 meters are installed. They are able to skip 6.10 or 16 m3 per hour.

In addition to throughput, the design must meet the conditions:

• The gas meter is designed for a network operating pressure of not more than 50 kPa;
• Fuel temperature can vary within -300 to +500 C;
• The ambient temperature ranges from -400 to + 500 C;
• The decrease in pressure does not exceed 200 Pa;
• Verification is performed every 10 years;
• Measurement error does not exceed plus or minus 3%;
• Sensitivity - 0.0032 m3/hour;
• The service life of the gas meter is at least 24 years.

The buyer should pay attention to the dimensions of the devices. They should not be too heavy and large so as not to take up much space.

There are many types of blue fuel metering devices on the Russian market.In order for the meter to meet all the requirements of the consumer, it is necessary to take into account all the parameters of the equipment installed in the house or apartment.

Gas meters for a private house: installation price, necessary conditions

Installing a gas meter requires certain financial costs. The main ones are the following:

• purchase of a meter;
• payment for the development of "Technical conditions";
• costs for the creation of the “Installation Project”;
• payment for installation work.

To exclude the claims of gas service specialists when putting the meter into operation, it is worth knowing the basic requirements for its placement. They are regulated by SNiP 42-01-2002 and SP 42-101-2003. Regarding the gas meter, the rules are as follows:

• the location must be accessible for installation, maintenance and repair;
• installation height (from the floor to the meter) - at least 1.5 m;
• the meter should be placed at a distance of at least 1 m from gas-consuming equipment (columns, stoves, boiler);
• the metering device can be installed in an adjacent room, separated from the one equipped with gas appliances by a wall with a doorway;
• the meter must be removed from the wall by 3-5 cm to create anti-corrosion conditions.

More demanding outdoor gas meters for a private house. The price of their installation significantly exceeds the cost of installing a room version due to the need to perform more work and use materials. The output of the gas meter to the outside is additional pipes, the manufacture of a visor or box to protect the device from sunlight and precipitation.

 
The price of installing outdoor gas meters significantly exceeds the cost of installing indoor models. Note! To place the counter, it is better to choose a room with good ventilation. In the absence of it, experts will prohibit installation in such a place or require ventilation.

32. If subscribers (individuals) do not have gas meters, the volume of its consumption is determined in accordance with the gas consumption standards. Norms and norms of gas consumption are approved in the manner established by the Government of the Russian Federation *** Is it really profitable to install apartment gas meters?

An ordinary family consumes gas by about 30 rubles a month. If the family cooks little, they can pay 5-10 rubles according to the meter. The whole difference between what you pay now and these figures is your savings. Considering that the average gas tariff now in many regions of Russia is 43 rubles.per person, then for three people 3x43 rubles. - 30 rub. ≈ 99 rub. savings per month, per year - 1188 rubles; - for four people 4x43 rubles. - 30 rub. ≈ 142 rubles savings per month, per year - 1704 rubles; - for five people 5x43 rubles. - 30 rubles. ≈ 185 rub. savings per month, per year - 2220 rubles. That is, in almost a year with a little, and sometimes less than a year, you pay for the meter. And since our energy tariffs are constantly growing, the savings when paying by meters will be even greater. (Remember how much less you began to pay after installing meters for hot and cold water).

***

In our gas industry, they require to conclude a contract for the maintenance of a gas meter installed by me and, of course, pay for it monthly. Are these claims correct? I do not understand what needs to be serviced in the gas meter?

Household gas meters do not need special maintenance, with the exception of periodic verification, which is carried out by special laboratories accredited by the State Standard of Russia. The passports for most gas meters indicate that the meters are maintenance-free. Especially to exclude interference in the operation of the meter, at the manufacturing plants, and subsequently during periodic verification, the meter housings are sealed with special seals. So the requirements for the maintenance of meters are illegal, and they are not provided for by GOST R 50818-95 "Volume Diaphragm Gas Meters" *** I have an AS-250 meter manufactured by the Technogaz-AMK Joint Venture. The Gas Industry Trust requires its replacement due to the expiration of the calibration period. But they say that this counter is not being produced now.Which counter can I replace it with so as not to use welding for replacement, as it is expensive. At gas meter replacement AC-250, you can install the G-6 "Metrix" counter with almost the same center distance produced by the Polish company "Metrix". No welding work is required to replace the AC-250 meter you have installed with the above one. It is necessary to purchase the meter together with nuts and threaded fittings Du 20, since it is necessary to change the fittings installed for AC-250 with nuts that have an "American" thread.

Varieties of gas meters

To know how to choose a household gas meter, you need to understand the differences between different types of gas meters for an apartment.

According to the principle of operation, apartment gas meters are divided into three categories:

membrane type. The choice of a gas meter of this type may be due to the possibility of a simple cheat of indicators. But this type of gas meter for an apartment has its drawbacks: during operation, it may stop showing accurate data, it will creak and gradually fail. The accuracy of the device is affected by magnetic fields, so even immediately after purchase you cannot be sure that it will measure the flow correctly. And all this at a fairly high cost: from 20 to 100 USD;

the next type of gas meters is electronic.Compared to the first type, it has a higher cost (up to $ 200), but also more reliable performance. If you are looking for which gas meters are best for an apartment, then you can opt for such devices, as they show fairly accurate data. And checking such a meter for gas in an apartment needs to be done only once every 10-12 years;

a rotary apartment gas meter is another popular type of metering device. It is great for domestic conditions, has small dimensions, practically does not make noise during operation. But it should be checked every 5 years. At the same time, the counter has an affordable cost, therefore it is one of the most common in apartments.

So which gas meter is better to put in an apartment? It all depends on the approximate volume of gas consumption. In the presence of an individual heating system, any type of such devices is suitable.

If you need gas exclusively for a stove or column, get a rotary or electronic form.

Which gas meter to choose depends on other factors. Let's discuss this in more detail.

Why is it important to choose the right meter

In a private house, there are three important devices that consume household gas - a gas stove, a water heater and heating. A lot of blue fuel is consumed, and since its price can hardly be called low, besides, it is steadily growing from year to year, it is useful to consider accounting for consumed fuel.

The device will not pay off soon, in 3-4 years, since it is quite expensive, and these are not all of its shortcomings. These include the noise of some models, large dimensions.

It is important for every homeowner to know the types, advantages and disadvantages of metering devices, and, despite the recommendations of gas workers, make the right choice for their home.

Verification frequency

The counter needs to be checked for correctness and correctness of data reflection. For different types and models of metering devices, this period is different and is indicated in the technical passport.

The first verification takes place after the production of the meter at the factory. Information about this is entered into the product documents. It is from this moment that the countdown begins until what time it is necessary to carry out the next verification, and not from the moment of installation.

It turns out that if you bought metering equipment three years after release, and the frequency of verification is 10 years, then you will have to perform the procedure in 7 years.

If you missed the verification, then the accrual of payments to you will be made according to the standards. And so on until the event is completed.

Household gas meters in the apartment

The peculiarity of this type of PU lies in the relatively low throughput - from 6 to 25 cubic meters. This is quite enough for an apartment with a stove and a column, and for a house with a gas boiler.

CBSS 1.6 Betar

The Betar household gas meter is designed for operation exclusively at home. Operating temperature range is from +10°С to +50°С. Such a device has a fairly compact size, which allows it to be installed even in small kitchen rooms.

Gas meter SGBM 1.6 Betar

The device can be mounted both vertically and horizontally. The model is equipped with a screen that will inform the user about the current data.

The controller has the following parameters:

• maximum gas flow - 1.6 m3/h;
• nominal working pressure - 5 kPa;
• weight - 0.7 kg;
• price - from 1900 rubles.

The device has a lithium battery, which acts as an energy source for the gas appliance. Without a battery, the counting information will not be displayed on the LCD screen. As for the replacement of this battery, it will be required no earlier than 12 years.

User manual SGBM 1.6 Betar

SGK G4 Signal

One of the most accessible and popular devices is considered to be the products of EPO Signal LLC. SGK 4 has a maximum limiting gas flow rate of up to 6 m3/h, while the nominal pressure level is 3 kPa.

Verification should be carried out by specialists with subsequent sealing and the issuance of a document on the timing of the verification and the organization of the work carried out.

Counter cost

You can buy the device in various trade organizations. These can be specialized stores, construction and household outlets, online sellers. The price of this device varies widely from 4500 rubles and above.

Particular attention should be paid to the reliability of the seller, the guarantee issued and properly executed documents. This is due to the subsequent reliability of operation and safety.

Why do you need a gas meter?

Some consumers of gas in the old fashioned way pay for it according to the standards, citing the fact that the cost of a meter with installation is prohibitively high.

Indeed, they have such a right, but economically it is very unprofitable. Why is this happening?

Firstly, the fee according to the standards is initially overpriced. It is calculated according to the maximum gas consumption, which is extremely rare in real life, if not at all.

Payment according to the standards takes into account the maximum of all possible options for gas consumption by each person living in an apartment or house. If there are two or three tenants, or even more, the amounts are not small.

In addition, the state is interested in the fact that the consumed resources are recorded by metering devices, therefore, the current legislation provides for increasing coefficients that increase the payment for gas according to the standards. Over several years, this ratio gradually increases until it reaches a maximum.

Installing a gas meter makes it possible to pay for the actually consumed energy resources and makes you think about saving them

Whereas installing a meter involves paying only for the amount of gas actually consumed.Practice shows that it differs significantly from that calculated according to the standards. Accordingly, the fee is significantly reduced.

The real difference in payment allows you to quickly recoup the cost of purchasing and installing a metering device, and subsequently receive significant benefits from this.

For those who have autonomous gas heating, installing a meter provides another advantage. They can use their heating equipment regardless of the start or end of the heating season.

Consumers who do not have metering devices are automatically disconnected from the gas supply after the end of the heating season until it begins. Installing a counter solves this problem.

Before contacting gas workers with an application for installation and sealing of a gas flow meter, you must select and buy a device. And this is not easy, because there are an impressive number of them on the market now. According to the principle of operation, all gas consumption meters are divided into the following groups:
