摘要： PROBLEM TO BE SOLVED: To provide a gas cutoff system for accurately, speedily determining leakage and monitoring it without being affected by an apparatus plug state, when it returns from abnormal usage cutoff of the apparatus.
SOLUTION: The gas cutoff system measures the signal propagation period in a medium and detects the flow velocity with a flow velocity detecting means 17 to monitor the using state of the gas apparatuses, converts the detected flow velocity into a flow rate with a flow rate calculating means 25, and determines with an abnormality determining means 26 whether the using flow rate calculated by the flow rate calculating means 25 is a normal value. When a flow channel 1 is blocked by a blocking means 27 at abnormality determination time, for reusing the gas, a return signal is outputted to the blocking means 27 by a returning means 28 to open the flow channel 1. Simultaneously, clocking is started by a return clocking means 29. After a predetermined time, when a leakage determining means 33 determines that the pressure is reduced to a predetermined pressure or lower by a pressure detecting means 30 for detecting the pressure in the flow channel in order to recognize that gas plugs of all the gas apparatuses connected to the downstream of the gas cutoff system, a driving signal is outputted to the blocking means 27 to close the flow channel 1.
