Statement of the problem. The algorithm of the program “Control of Energy Resources: CER 1-gas” designed to quickly calculate the maximum permissible error of measurement by the gas meter in relative units (%) and in absolute value (m3/h) at the current set gas flow rate for various types of meters needs to be improved.Results. The major issues of programming physical processes for measuring low gas flow rates are discussed. A description of the program for measuring low gas flow rates is shown. A computer software and an operation algorithm “Energy Resources Control: CER2-main” have been developed that automate the calculation of the maximum permissible measurement error by the gas meter in relative units (%) and in absolute value (m3/h) at the current specified gas flow rate, diameter, pressure for various types of counters taking into account the linear velocity of particles in the gas flow.Conclusions. For the first time, the EMV software “Energy Resources Control: CER 2-main” has been designed aimed at quickly calculating the maximum permissible measurement error of the gas meter in relative units (%) and in absolute value (m3/h) for the current specified gas flow rate, pipeline diameter, pressure for different types of meters, which makes it easier to check their performance during periodic verification. The results obtained meet the objectives set in the “Energy Strategy of Russia for the Period up to 2030” (No. 1715-r dated October 13, 2009) and are intended for use in the modernization of gas consumption systems and accounting for low energy costs. The studies assume the adaptation of the basic methods for assessing the reliability, risks and safety of systems in the theory of gas supply and regulation of gas consumption metering employed by regional enterprises of the gas industry.
