AB - As a result of the conducted studies, a mathematical model of airtightness of the pneumatic system in installations with reference gas meters was obtained. With the help of the obtained dependences, it is possible to determine the permissible value of the pressure change in the pneumatic system during the passage of the reference volume of gas during the calibration of gas meters. The permissible volume change is determined due to the leakproofness of the pneumatic system of the installation and gas meters, which does not affect the reliability of the results of the gas counters verification. That is, in choosing this norm, it is necessary to consider: the control volume which will be passed through the gas meter at its verification; checking time, pressure in the pneumatic system of the installation when checking the gas meters, the permissible value of the error of the gas meters and the installation.
