Choosing a gas meter NPM G4: review, characteristics, verification, passport

Gas meter Gazdevice NPM G4 is a membrane measuring device designed to measure consumed gas with non-aggressive properties. The product can be used by any individual consumers, including owners of private houses and apartments, utility organizations and enterprises, if the hourly flow rate at installation sites does not exceed 6 cubic meters.

Type of meter – Gasdevice NPM G4

Design and principle of operation

The device is made with the following components:

housing, including two halves, hermetically connected mechanically, inlet and outlet pipes;
a measuring mechanism divided into two parts, each of which is equipped with a membrane;
crank assembly;
spool distribution system;
mechanical counting unit with rollers;
pulse sensor type reed switch (for a separate modification).

Sectional view of a gas meter

As a result of the alternating actuation of the membranes in the measuring half-chambers, the translational motion is transmitted through the connecting rods to the crankshaft and, through a gear drive, to the counting unit. The scaling gear ensures the position of the rollers on the display corresponding to the measured volume of the gas mixture used.

Models with pulse output allow you to connect the device to a centralized monitoring system. The reed switch of the sensor is periodically triggered by the influence of a magnet, which is equipped with the outermost roller of the counting unit.

When should the device be replaced, after how many years?

Let's consider how often the device needs to be changed, and after how many years it must be replaced. According to the standard, if the meter has passed all verifications and worked properly, then it is replaced at the end of its service life (from 8 to 20 years) specified in the technical passport. But there are cases when the device needs to be changed ahead of schedule:

The seals are broken.
The numbers on the device display are not shown.
Presence of damage incompatible with the operation of the device.
The meter did not pass verification, or during verification, violations were identified that made further operation impossible.

The following factors may affect the service life of the meter:

Low bandwidth.
Increased humidity in the room.
Incorrect meter installation.
There are no dust filters.
The installed cells do not meet the technical requirements.

On the pages of our website you can read articles on the topic of servicing gas equipment and installing a meter in an apartment or private house.

How does operation affect the period of use?

The operation of a gas meter, like any other measuring device, affects its performance. This may manifest itself in:

the occurrence of interruptions that affect the recording of readings;
the appearance of noise;
constant interruptions;
frequent errors when accounting for consumed resources.

That is why any meter must be constantly checked and, if necessary, repaired or replaced. You can find out about the timing of gas meter inspections separately.

The device may fail if the user violates the operating conditions specified in the passport. If all necessary requirements are met and provided, the service life of the meter will be as long as possible.

Meter dimensions – Gasdevice NPM G4

Gas meter NPM g4: characteristics and verification period 2021

has been producing NPM G4 gas meters for over 20 years. During this time, the company's products managed to conquer the Russian gas equipment market, taking one of the leading places in it in terms of customer reviews, quality, reliability and price.

The production facilities of the enterprise are located in the Moscow region. All of the company's products are manufactured on Italian equipment under a European quality control system, supported by a certificate of conformity.

I propose to consider in detail the NPM-G4 gas meters, prices, operating principles and internal structure, model range and technical characteristics, verification periods and temperature range of the device, according to the passport and operating instructions of the flow meter.

Model range of NPM gas meters (left, right) and their purpose

Today it supplies several models of household gas meters for private houses and apartments, for installation on a horizontal section of a gas pipeline:

Gas meter NPM G4: left

— Omega G1.6; — Omega G2.5; — Omega G4.

Gas meters NPM and OMEGA differ in the nominal gas flow rate, measured in m3/hour. This is indicated by the numbers in the name of the flow meter: 1.6; 2.5 or 4. This indicator corresponds to the purpose of a certain modification. Let's look at a few examples.

A gas meter with a nominal gas flow rate of 1.6 m3/h can only be used for a gas stove or surface. And the model with a flow rate of 2.5 m3/h is already designed for a gas water heater.

The NPM-G4 gas meter is designed for two gas appliances: stove + water heater or stove + gas boiler, floor-mounted or wall-mounted, single- or double-circuit.

The NPM gas meter can be right-handed (right-handed) or left-handed (left-handed). This indicator depends on the direction in which the gas flow moves relative to the meter. If the movement is from left to right, then the counter is “left”; if it is from right to left, then it is “right”.

On top of the device body this direction is indicated by a special convex arrow, so it will be difficult to confuse it. It is necessary to remember the location of your gas appliances relative to the meter; if they are to the right of it, then the meter is “left”, if to the left - “right”.

Omega gas meters G-1.6;-2.5;-4 from are designed for outdoor installation. This became possible thanks to the built-in temperature compensator for correct calculation of device readings at low temperatures from - 40 °C. As a rule, these “street” meters must be installed in a special box (cabinet) for gas meters, of the appropriate size and according to the design.

Device, principle of operation and dimensions

NPM gas meter: dimensions, fitting diameters

On the display we can see eight drums with numbers, the serial number of the meter (individual for each device and matching the number in the passport), technical parameters, as well as the year of manufacture.

The operating principle of the counter is based on the movement of internal membranes. The counting mechanism is activated due to the movement of the gas flow through a multi-lever system and a built-in gearbox, which are triggered by the movement of the membranes caused by the pressure of the gas flow on them.

Verification period

NPM G4 "Gazdevice" meters have a calibration interval of 10 years, starting from the date the device was released at the factory. After 10 years, the flow meter must be verified by special gas services. After it passes, the counter can work for the same amount of time.

Due to the fact that verification is expensive, many consumers simply buy a new meter, avoiding these procedures. The manufacturer guarantees uninterrupted operation of the equipment only for two years.

Technical characteristics of NPM Gazdevice gas meters

NPM G4 gas meters have threaded fittings for connection to a gas main with a diameter of 1 1/4″ (32 mm). The center-to-center distance between the fittings corresponds to 110 mm. All these parameters must be taken into account, especially if you are planning to replace the NPM meter with a flow meter of another brand, its equivalent.

For example, the following meters are suitable instead: imported “Elster” BK G4, St. Petersburg “Triton” G4 (under NPM) or Saratov “Signal” SGK-G4 (under NPM) with the same diameter of union nuts 1 1/4″.

NPM Gasdevice meters: technical characteristics

— European quality; — high measurement accuracy; — gas inlet pressure stabilization function; - light weight; — verification interval 10 years; — low price from 2000 rubles; — presence of a mesh filter at the inlet.

The only disadvantage is that adapters for connection (for welding or for 3/4″ threads) are not included in the meter package and must be purchased separately.

Today we examined in detail the gas meters NPM G4 "Gazdevice", the differences between the models, features, technical characteristics, verification periods. We examined the device according to its passport, and also noted the main advantages and disadvantages of Russian-made gas flow meters manufactured using European technologies. Let's watch the video review.

Household diaphragm gas meter NPM G1.6; G2.5; G4

Volumetric diaphragm gas meters NPM (G1.6; G2.5; G4) are designed to measure the volume of gas passed through them.

The main area of application of meters is housing and communal services in everyday life.

Significant discounts for wholesale buyers!

A volumetric diaphragm gas meter consists of a chamber-type primary flow transducer and a mechanical reading device, combined in one unit. The central body of the block is divided into two parts. Each part is divided into two half-chambers by an elastic membrane. The gas flow distribution mechanism includes a valve device connected to a volume indicating system. The gas flow is created due to the pressure difference at the inlet and outlet of the meter. The volume of gas passing through the meter is converted into readings on a roller-type reading device.

Technical characteristics and functional description.

Gas meters, type NPM, are designed in accordance with Russian and International EEC standards.

These gas meters can be used to measure all commonly used gaseous fuels, such as:

natural gas;
liquefied gas vapors;

The Gazdevice NPM G4 household gas meter has small dimensions, which allows it to be used both in industry and at home. It can measure the consumption of any non-corrosive fuel. The NPM G4 gas meter is highly accurate; even a partially contaminated working environment will not affect the quality of measurements. Most often, this device is used in everyday life to control resource consumption of home appliances. An analogue of this metering device is the VK4 flow meter, manufactured by Elster. It has similar technical characteristics, operating rules and appearance.

The operation of the device, developed and produced at Gazdevice CJSC, is based on a diaphragm (membrane) method for measuring resource consumption. The fuel passes through special chambers equipped with membranes. Depending on the speed of gas movement, the speed of vibration of the membranes changes. Next, with the help of special internal devices, the translational movement of the diaphragms is converted into a rotational movement of the measuring mechanism, as a result of which the indicators change.

Users and specialists highlight the following advantages of this metering device:

High degree of sensitivity. The process of accounting for resource consumption begins even at a minimum consumption level.
Low error. This allows you to be sure that the performance of the device that was developed and produced fully reflects the actual level of consumption of natural resources.
Availability of built-in protection against illegal changes in indicators. This eliminates the risk of administrative and criminal liability for violation of the contract for the supply of natural resources.
Ability to work with uncleaned working environment. The presence of impurities and foreign particles does not affect the accuracy of the indicators of this meter.
Wide temperature range in which the meter remains operational. This feature allows you to install the flow meter even on the street, without fear of its unexpected stop or breakdown.
Almost all user reviews are positive. The main features that stand out are the accuracy of measurements, convenient dimensions for installation and obtaining indicators, and the high reliability of the metering device.
The verification period is 10 years. This allows you to spend minimal money on ensuring the operation of the device and its maintenance.
Reliable operation regardless of changes in pressure level in the system. The accuracy of the indicators practically does not change with its differences.

Device warranty

If the device fails due to improper workmanship, the manufacturer provides the opportunity to repair or replace the product free of charge if less than 2 years have passed since the installation of the meter, and no more than 3 years have passed since the initial verification at the factory.

The manufacturer's warranty obligations apply to products for which the consumer and dealer complied with the passport conditions of transportation, storage, installation and operation. A mandatory condition of the guarantee is the provision of the original passport containing marks of factory verification and installation.

At the same time, the manufacturer guarantees compliance of the device with the stated requirements and state standards.

Life time

The manufacturer provides a warranty on its devices for a period of 2 years. The warranty covers repairs and replacement of faulty parts, subject to:

having a passport,
compliance with the conditions of transportation, installation and operation,
absence of mechanical damage,
presence of factory seals.

We recommend: Gas meter Vector G4

If you follow the operating conditions specified in the passport, the meter will last more than 20 years. The calibration interval is 10 years; after this time, the meter should be checked by a specialized gas service. There they will check the accuracy of the readings and the performance of the meter, after which it can be installed again. The optimal temperature for operation of the device is from -40 to +60 degrees Celsius.

Advantages of the device

The device is characterized by the following positive differences:

inexpensive price;
simplicity of design, ensuring durability and excluding unauthorized influence;
availability of the function of remote transmission of information;
modern attractive design;
low measurement error;
selection of designs that differ depending on installation conditions;
ease of taking readings;
high-quality components and case processing that eliminates corrosive wear.

Taking readings

The recorded volume is displayed by a drum display on which:

The 5 left rollers indicate the integer value of the cubes (blue frame) ;
three to the right after the decimal point, differing in color - a fractional part that is not used when taking readings (red frame) .

Taking readings from the meter – Gazdevice NPM G4

Credentials are removed as follows:

Record the number of cubes on the dial, omitting the leading zeros.
Data from the previous measurement are subtracted from the measured value.
The result is multiplied by the size of the tariff plan.

Is it possible to save money?

The very fact of installing a meter significantly reduces the payment amount due to the possibility of reducing fuel consumption and lower prices - calculation according to standards will cost the consumer significantly more.

By reducing consumption by installing energy-efficient consuming appliances and judicious use of gas, the consumer has the opportunity to further reduce gas costs.

The mechanism of the device provides a stopper that prevents the rollers from moving back. The design uses non-magnetic materials and alloys, so the use of a magnet will not have the desired effect, but if detected, it will lead to the imposition of serious penalties against the violator.

How long will a G6 gas meter last?

The two-chamber meter has increased throughput and can be used in both domestic and industrial applications. This metering device is installed in administrative institutions, in a private house or apartment with several devices that consume natural gas.

Several devices can be connected to the SGMN-1M G6 meter simultaneously, for example a gas stove, boiler and water heater.

The main advantages of this metering device:

high sensitivity – measurement begins even at minimal flow;
silent operation - the device does not make noise or crackle, so it will be appropriate in any living space;
small dimensions;
when gas passes through the device, the pressure in the line does not change;
the operation of the device is practically independent of temperature changes - outdoor installation is acceptable;
the meter is able to work even with a contaminated gas environment;
a reliable flow meter does not require frequent verification.

We recommend: What is convection and why is it needed in an electric oven?

The minimum service life of SGMN-1 G6 is 20 years, the interval between verifications is 8 years. A verified meter is considered to be working, so if the service life of the current meter has expired, it must be sent for verification. The owner of the gas equipment is responsible for the timely completion of this operation, and the use of an appliance with an expired verification period is tantamount to its absence.

Meter installation

The installation of the device is carried out by a company that has received a license and permission from supervisory authorities to perform hazardous types of work. This organization is engaged as a gas fuel supplier. Installation prices range from 6 – 8 thousand rubles.

Installation is carried out in accordance with the manufacturer's instructions in the passport documentation, based on the developed project.

Dimensions and installation standards for stove meters

When the installation is complete, the person representing the gas supply company places protective seals on the device, including the connection points. Commissioning is confirmed by an entry in the corresponding column of the meter passport.
