摘要： PROBLEM TO BE SOLVED: To improve the safety and prevent a wasteful gas consumption by opening the plug of a gas passage only when gas is used and measuring the instantaneous quantity of flow and opening the gas passage only when the gas is used and to prevent a wasteful electric power consumption by measuring the instantaneous quantity of flow only when the gas is used.
SOLUTION: When a control means 2 detects a signal from a pressure varying means 9 while the plug 3 is closed, the control means 2 determines that gas use is started, outputs an opening signal, and simultaneously transmits a measurement start signal to an instantaneous flow quantity measuring means 1 to start measuring the quantity of flow. At the reception of the opening signal, a valve opening drive means 4 outputs a valve opening drive signal to the valve 3 to make the valve 3 open the gas passage. In the case that the gas use is halted, a flow halting determining means 7 outputs a signal to the control means 2. The control means 2 outputs a closing signal, and simultaneously transmits a measurement halting signal to the instantaneous flow quantity measuring means 1 to halt the measurement of the quantity of flow. At the reception of the closing signal, a valve closing drive means 5 outputs a valve closing drive signal to the valve 3 to make the valve 3 close to the gas channel, thereby opening the gas passage only when the gas is used.

摘要： PROBLEM TO BE SOLVED: To reduce the consumption of electric power consumed in a control circuit. SOLUTION: The gas measuring apparatus is constituted of an ultrasonic wave-type measuring part which measures the consumption amount of a gas. The measuring apparatus is constituted of a pressure sensor 8 which measures the pressure of the gas. The measuring apparatus is constituted of the control circuit 7 which controls the ultrasonic wave-type measuring part. The measuring apparatus is constituted of a measurement starting means 10 which starts the measurement of the consumption amount of the gas on the basis of a signal from the pressure sensor. The measurement starting means 10 detects the signal from the pressure sensor 8 so as to confirm that the pressure of the gas exists, and it supplies the electric power to an ultrasonic-sensor drive circuit 9. Only when the pressure of the gas exists, a flow rate is measured. As a result, the consumption of the electric power consumed in the control circuit can be reduced.
