Selection of an alternative option for gas flow meters through a comparative

analysis of modern gas meters and the implementation of measures to reduce the errors of

modern gas meters.

A gas meter is a device that measures the volume of gas passing through per unit of time; it is

designed for natural and other non-toxic gases. Depending on the operating mode, there are

diaphragm, turbine, rotor and other types. In diaphragm gas meters, the measuring device

consists of two chambers separated by gas-tight diaphragms.
Thanks to a system of special valves, the diaphragms move back and forth due to the difference

in gas pressures the inlet and outlet tubes of the meter. The kinematic device converts this

movement of the diaphragms into the rotational movement of the rollers of the unit. Such gas

meters are used in households. In a turbine gas meter, the flow straightener balances the gas

flow through the turbine. The measuring mechanism consists of a bladed turbine and a gearbox,

the turbine axis is fixed on two supports. A magnetic transmission transmits the rotation of the

turbine to the computing device. A roller accumulator in the meter measures the volume of gas

passing through the meter. Such a gas meter works with low, medium and high pressure gases,

it can be connected to various measuring devices. Such counter gas used in industry .

Types counters gas

There are different types of gas meters:
- communal;
- industry;
- family;

Industrial gas meters

It is also divided into classes according to gas consumption.
Their types according to the principle of operation:
- With rotor ;
- turbine ;
- whirlwind ;
The turbine gas meter is a very complex mechanism and is sold at high prices.
Modern turbine meters are equipped with electronic systems that display gas consumption,

continuously check the system, detect errors or signals about damage during the operation of

the equipment, and send signals to a remote monitor. In addition, the meter gives an alarm

signal about cases of unauthorized connection to the system.

Industrial gas meters

Thus, these meters are intended for installation in industrial enterprises or gas pipelines. The

rotary gas meter is a more common meter. Its high cost is due to the prices of materials used in

its production. The operating principle of the meter is very simple - inside it is a rotor rotating

under the influence of gas. This meter is designed for a gas consumption of 200 cubic meters

per hour.

Domestic gas meter

Rotary meters can be installed in a private home or at industrial enterprises with low gas

consumption. The advantages of this meter are small dimensions, light weight, long service life.

Membrane gas meters are mainly installed in apartments, private houses, cottages. This meter is

designed for a consumption of 12 cubic meters of gas per hour, has high accuracy and

reliability, as well as a low price.
The vortex flow meter is the most complex device for measuring gas flow. This flow meter has

the highest accuracy and passes a large amount of the gas it consumes. The vortex flow meter is

installed only in large enterprises whose production process is based on gas consumption.

Gas measurement methods

Currently, the following methods are used to measure gas and substance consumption:
- direct (correct) measurement method;
- general measurement method;
- method of joint measurements;
- method of indirect measurements.
Flow rate is the amount of a certain substance passing through a pipe cross-section per unit of

time.
The amount of a substance can be measured both in units of mass (kg, t) and in units of volume

(m

3 ,

l).

Mass units can provide more complete information about the amount or flow rate of a substance

than volume units, since the volume of a substance, especially gases, is highly dependent on

pressure and temperature. When measuring the volumetric flow rate of gases, the value of the

results being compared is reduced to certain measurement conditions (standard conditions).
The relative error of gas meters consists of determining the loss of gas flow through the meters

in the manner established by specific types of meters and regulatory documents.
The accuracy of the flow rate is specified in the regulatory documents for a specific type of

meter.
State acceptance, control and periodic tests, as well as in the measurement range. (0.9-1) Q

during additional checks, the relative error is determined and calculated.
The flow readings of the meter are compared with the meter being tested and the reference

measuring instrument at least three times in accordance with the established requirements.
The relative error in percentage is found using the following formula.
