Abstract
An object is to detect an abnormality when the inside of a gas cutoff apparatus is submerged. A flow rate computing unitcomputes an instantaneous flow rate from a detected value of a flow rate detecting unitfor measuring a flow rate, and an amplification degree determining unitdetermines signal amplification adjusted by the flow rate detecting unit, and timing is started when the amplification degree is a predetermined value or more, and a measurement condition setting unitsets a measurement condition of the flow rate detecting unitfrom the flow rate obtained by the flow rate computing unit, and a measurement ratio computing unitobtains a measurement condition ratio during predetermined time from a time measuring unitand the measurement condition setting unit, and it is determined that the flow rate detecting unitis abnormal when the measurement ratio is a predetermined ratio or more, and a cutoff unitbreaks supply of gas.
