摘要： PROBLEM TO BE SOLVED: To provide a gas safety device for not causing an erroneous operation, when measuring flow rate according to pressure change by sensing the installa tion of a gas implement for bringing about the pressure change such as a GHP or the upstream side from the device. SOLUTION: The gas flow rate of a gas channel 4 is measured from an instantaneous flow rate, sensed by an ultrasonic sensor 3 under the control of an ultrasonic sensor drive circuit 2 by a control circuit 1. A fault occurs in the measurement of the sensor 3, when the gas implement for bringing about the pressure change, such as GHP is installed at the upstream side from the channel 4. Accordingly, when times which are set beforehand during a unit time and the change exceeding a preset change range are detected during the unit time by a GHP-deciding means 8, it is decided that the GHP has been installed, and then it is controlled to make the driving interval of the sensor 3 changed.

摘要： PROBLEM TO BE SOLVED: To provide a gas-blast circuit-breaker to rapidly detect a flow rate at the pilot burner of a combustion apparatus and promptly decide the presence of a flow rate at the pilot burner based on an instantaneous velocity of flow. SOLUTION: A velocity of flow detected by a velocity of flow detecting means 12 through measurement of a time to transmit a signal through a medium is converted into an instantaneous flow rate by a flow rate computing means 18. When it is decided by an abnormality deciding means 19 that the instantaneous flow rate is abnormal, a medium flow passage is cut off by a cutoff means 20. When the instantaneous flow rate is lower than an apparatus flow rate and except a case that a flow rate is zero, it is decided by a minimum flow rate deciding means 21 whether a flow rate is a minimum value. A minimum flow rate is detected and a minimum value lower than the minimum flow rate is registered and updated by a minimum flow rate memory means 22 to store it. After it is decided by a nozzle clocking, clocking a period in which an apparatus nozzle flow rate is observed, that a given period elapses, the minimum value is nozzle-registered by a nozzle registration means 24 but when it is decided by a flow rate zero deciding means 25 that the instantaneous flow rate is zero, the deciding result is set as non-nozzle.
