METHOD OF LOCATING LEAKS OF GAS FROM MAIN Russian patent published in 1998 - IPC

Abstract RU 2119610 C1

FIELD: remote check of gas mains for condition and protection of mains; automatic control systems of gas transport. SUBSTANCE: method consists in check of flow rate of fuel gas used by gas turbine drives of pumping units of compressor stations at the beginning and at the end of linear section of gas line, determination of amount of mismatch between them, comparison of this magnitude with preset permissible magnitude of mismatch; in case this magnitude is exceeded, control action for locating the leak in the gas line is generated. EFFECT: enhanced operational reliability of gas pipe line. 1 dwg
