Filed: 1986-11-17
Abstract: PURPOSE:To improve safety, by a method wherein a flow rate pattern of gas is measured for a given period, and through comparison of an actual state with an initial condition, a deciding condition matching an actual state is reset. CONSTITUTION:With a starting signal applying means 12 actuated, a starting signal is sent to a timer, and the timer inputs the signal to start counting during a given period. Simultaneously with actuation of the timer, a using state memory part 13 stores a using pattern of gas, i.e., a total flow rate, an individual maximum flow rate, a continuous using time. A gas proper using condition varying part 14 updates data in order to store the maximum value of an actually measured using pattern. When counting by the timer is completed, final data is sent from the memory part to the proper using condition varying part 14. The varying part 14 compares an initial condition with final data, and by selecting either, having a smaller value, of the initial condition and the final data, i.e., a proper using condition is newly set to the safety side. Namely, since, when deviation from the condition occurs, a shut-off means 4 is actuated to stop gas, a hazardous state, gas explosion, gas intoxication, can be prevented from occurring.
