It is known that the area of the implementation of automated systems for remote control of the technological processes of gas transportation and distribution, as well as its commercial metering and consumption is set for the settlements with population exceeding 100 thousand people. It has a centralized structure, including the lower level − controlled stations, and the upper level − central dispatcher board, which is implemented in the form of automation-equipped workstations connected using computer networks.

Frequent cases of domestic gas explosions require a more detailed study of gas use in terms of ensuring the safety and maintenance of equipment when providing public services for gas supply. The study of the theory of gas consumption accounting in cases of establishing homogeneous phenomena occurring in gas supply systems is shown in the developed method of correlation and  regression analysis.

The article notes that the organized supply and distribution of gas fuel for the needs of agricultural enterprises, as well as the population, is of great importance. The conclusion is made about the necessity of mandatory energy inspection of gas transportation through pipelines.

Statement of the problem. It is required to improve the algorithm of the program “Control of Energy Resources: KEP 1-Gas” designed to quickly calculate the maximum permissible error of measurement by the gas meter in relative units (%) and in absolute value (m/h) at the current set gas flow rate for various types of meters. Results. The major issues of programming physical processes for measuring low gas flow rates are investigated. A description of the program for measuring low gas flow rates is shown. A software package and an operation algorithm “Energy Resources Control: KER2-Main” have been developed which automate the calculation of the maximum permissible measurement error by the gas meter in relative units (%) and in absolute value (m/h) at the current specified gas flow rate, diameter, pressure for various types of counters considering the linear velocity of particles in the gas flow. Conclusions. For the first time, the EMV software “Energy Resources Control: KER 2-Main” has been developed which is designed to quickly calculate the maximum permissible measurement error of the gas meter in relative units (%) and in absolute value (m/h) for the current specified gas flow rate, pipeline diameter, pressure for various types of meters, which makes it easier to check their performance during periodic verification. The results obtained are in compliance with the objectives specified in “Energy Strategy of Russia for the Period Up to 2030” (No. 1715-r from 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 used for the operation of regional enterprises of the gas industry.
