FIELD: power industry.
SUBSTANCE: transmission system comprises primary flow meters which are arranged parallel to each other and each of which is configured to receive the primary measurement of gaseous fuel flow rate portion passing through the commercial transmission system and secondary flow meters located sequentially relative to the primary flow meters, and each of which is configured to receive the secondary measurement of gaseous fuel flow rate passing through the commercial transmission system, wherein each of the primary and secondary flow meters is arranged with a function to lock or unlock, respectively, ensuring prevention or admission of gaseous fuel supply based on the number of gas turbines in operation state.
EFFECT: improved accuracy of gas flow measurements and reduction of downtime caused by maintenance or calibration of transmission system flow meters.
