。 A flow rate detector is installed in the middle of the gas supply pipe that connects the gas cutoff valve installed on the gas supply source side and the gas supply pipe installed on the gas equipment side, and monitors the abnormal flow rate of the supply gas flowing through this gas supply pipe. The control circuit includes a determination unit that determines normality or abnormality based on the detection result of the flow rate detector, and a determination unit that determines whether the gas cutoff valve is normal or abnormal based on the detection result of the flow rate detector; A drive unit that operates the
An abnormal flow rate monitoring device comprising: a timer unit that causes the determination unit to start determination after a certain interval time when restarting monitoring of the abnormal flow rate by reopening the gas cutoff valve.
