摘要： PROBLEM TO BE SOLVED: To provide a gas-blast circuit-breaking device to delay cutoff when a demander uses a gas apparatus when lowering of a battery voltage is detected and a feed of gas is about to stop, and stops the use of the gas apparatus. SOLUTION: When lowering of the voltage of a battery source means 2 is detected by a voltage detecting means 10, a time elapsing after lowering is measured by a time measuring means 12 and after a lapse of a given time, a cutoff signal is outputted but when a flow rate indicating a use is detected, a cutoff signal is delayed by a cutoff signal delay means 16 and when a flow rate stops, a cutoff signal is outputted to stop a feed of gas. This constitution prevents gas from being suddenly cut off during the use of gas and improves facility and safety.

摘要： PROBLEM TO BE SOLVED: To diagnose whether a gas meter is normally integrating, by the meter itself by carrying out alarm processing in the case of an appropriate pressure deciding means judging the decrease (increase) of flow and deciding measured pressure to be lower (higher) than stored pressure. SOLUTION: A flow measuring part 21 provided at a meter inlet part 19 and a meter outlet part 20 measures the flow of passing gas. Gas pressure at the meter inlet part 19 when detecting gas flow is measured by a pressure measuring part 22 and stored in a memory 24. Thereafter, pressure is measured when detecting the increase or decrease of flow. The preceding pressure stored in the memory is updated with the measured pressure value, and the measured pressure value is compared with the stored pressure. It is supposed to be normal in the case of measured pressure >= stored pressure at the decrease of flow or measured pressure = stored pressure at the increase of flow, and an alarm is generated when abnormal.
