摘要： A gas flow rate is measured and therefrom "consumption state" defined by combination of maximum slow rate, increase of total amount and a consumption time of the gas is detected, and then, the consumption state is compared with a "reference consumption condition" representing a predetermined consumption state; and when the "consumption state" exceeds the "reference consumption condition", a gas control means interrupt supply of the gas; and thereafter, after restoration of the gas control means to gas supply state, the actual gas consumption state is measured for a predetermined time counted by timer when the gas flow rate exceeds a predetermined level.

摘要： PURPOSE:To obtain a stable gas interrupting device by temporarily setting an interruption condition from observation data in a short time at the initial stage of timer operation and after that, finally setting the interruption condition based on the data in a timer period. CONSTITUTION:An activation impressing device 12 is operated at a time t1 and timers 10 and 11 start counting. A period from the time t1 to a time t2 shows the counting period of the timer 11 and a safety coefficient K2 is multiplied to maximum data P1 in a gas use state observed in the period. Then, an arithmetic result is calculated and compared with a monitor level M1 corresponding to an interruption level L1. When the arithmetic result is less than the monitor level, the interruption level is multiplied by a prescribed value and a level L2 is temporarily set. Then, the timer 11 is started again. Samely, when a second prescribed period passes after a time t3 as well, the monitor level M2 corresponding to the L2 is compared with a value, which is operated based on the observed data, and an interruption level L3 is temporarily provided. At a time t4, a safety coefficient K1 is multiplied to a maximum value P2 of the observed data and an arithmetic result is obtained and compared with the initial condition. After that, a condition L4 in a safety said is defined as a suitable use condition.
