VAPOR LEAKAGE MONITORING SYSTEM

PROBLEM TO BE SOLVED: To specify a vapor leaking position and to improve monitoring certain ty by judging that a vapor leakage occurs in a vapor containing equipment when a pheromone is detected by either one of a plurality of pheromone detecting mechanisms. SOLUTION: A judging means 8 for judging that the vapor leakage occurs in the gas containing equipment 2 when either one of a plurality of pheromone detecting mechanisms 5 detects the pheromone is provided in a controller 10. A signal corresponding to a gas leakage occurrence state is turned on in a state with a detecting signal from either one of the pheromone detecting mechanisms 5 substantially in the configuration of the judging means 9. Therefore, configuration is adopted as the one where a 'gas leakage occurrence' signal is outputted as an output, an alarm lamp is turned on and an alarm buzzar is issued in the on-state. Thus, the gas leadage part position is specified.
