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 consistsof two chambers separated bygas-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, itcan beconnected to various measuring devices. Such counter gas used in industry . Typescounters gas There are different types ofgas meters: -communal; -industry; -family; page1578 INTERNATIONAL JOURNAL OF ARTIFICIAL INTELLIGENCE ISSN:2692-5206,ImpactFactor:12,23 AmericanAcademicpublishers,volume05,issue05,2025 Journal: https://www.academicpublishers.org/journals/index.php/ijai Industrial gasmeters It isalso divided into classes according togas consumption. Theirtypes according totheprinciple ofoperation: -With rotor; -turbine; -whirlwind ; Theturbinegas meter is avery complex mechanism andis 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 tothe system. page1579 INTERNATIONAL JOURNAL OF ARTIFICIAL INTELLIGENCE ISSN:2692-5206,ImpactFactor:12,23 AmericanAcademicpublishers,volume05,issue05,2025 Journal: https://www.academicpublishers.org/journals/index.php/ijai Industrial gasmeters 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 perhour. Domestic gas meter page1580 INTERNATIONAL JOURNAL OF ARTIFICIAL INTELLIGENCE ISSN:2692-5206,ImpactFactor:12,23 AmericanAcademicpublishers,volume05,issue05,2025 Journal: https://www.academicpublishers.org/journals/index.php/ijai 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 alowprice. The vortex flow meter is the most complex device for measuring gas flow. This flow meter has thehighest accuracy and passes a large amount of the gas it consumes. The vortex flow meter is installedonly inlarge enterprises whoseproduction process isbased ongas consumption. Gas measurement methods Currently, thefollowing methods are used to measure gas and substance consumption: -direct (correct) measurement method; -general measurement method; -method ofjointmeasurements; -method ofindirect 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 (m3,l).
