摘要： PROBLEM TO BE SOLVED: To avoid sensor anomaly determination in a temporary state out of assumed measurement conditions.
SOLUTION: A gas shut-off device includes a flow detection part 11, a flow calculation part 12, an anomalous flow determination part 13, a valve drive part 14, a valve 15, a return input part 16, an anomaly bypass part 17, and a sensor anomaly determination part 18.

摘要： PROBLEM TO BE SOLVED: To solve a problem in finding propagation time of ultrasonic wave in which information can be measured only on one direction by each single measurement before and after a switching operation, causing deviation to arise which is likely to lead up to a measurement error.
SOLUTION: A switching means 38 is used to switch between a transmission-side vibrator and a reception-side vibrator. By using an output of a reception means 35, a clocking means 36 measures propagation time of an ultrasonic signal reflected at least twice between the vibrators. A flow rate is calculated based on a clock value obtained by the clocking means 36. An average flow velocity and a flow rate calculation result can be accurately found since information pairing with a propagation direction is included in the propagation time of the reflected waves.

摘要： PROBLEM TO BE SOLVED: To provide an ultrasonic flowmeter with minimized power consumption by shortening a measuring time.
SOLUTION: This ultrasonic flowmeter comprises a counter 18 performing output to a timer in a case that output of a receiving circuit 16 is generated twice, and a control part 19 receiving time measured data from the timer 17. According to this, since the counter 18 outputs a stop signal to the timer 17, when output of the receiving circuit 16 is generated twice, to end a measurement, no interference is caused in receiving sound waves. Since the circuit scale can be thus reduced as well as reduction in power consumption of the circuit, an inexpensive and accurate flowmeter which is operable for a long time by use of a limited power source such as a battery can be realized.
