PURPOSE:To make it possible to ensure centralized monitoring of the leaking points of the gas by providing signal cables which are connected to distributed gas sensors along main pipes and branch pipes for gas supply, and controlling the dislay in a monitor station. CONSTITUTION:The signal cables 5... are connected to each of the gas leakage sensors 52-60... along the pipes. The sensors are distributed along the main pipes 1, 12, 13... and the branch pipes 21, 22, 23... for gas supply. Therefore, the leakage signal from the sensors 52... are transmitted by the cables 5.... Corresponding indicator lamps in the monitoring center O are controlled by the signals, and the centralized monitoring of the leaking points of gas can be positively performed. |
