摘要： PROBLEM TO BE SOLVED: To provide a low-power-consumption gas meter capable of obtaining a high-accuracy measurement value.
SOLUTION: A main counter 262 starts count according to generation of a main clock, and stops the count when an ultrasonic wave is received by the other ultrasonic sensor. When the ultrasonic wave is received by the other ultrasonic sensor, a sub clock generation circuit 263 starts generation of a sub clock of a frequency more than a prescribed frequency and less than two times. When the sub clock and the main clock simultaneously change or when a rising or falling change of the sub clock is generated two times during one period of the main clock, a comparison decision circuit 265 outputs a sub clock stop signal. A sub counter 264 starts count according to the generation of the sub clock, and stops the count when receiving the sub clock stop signal. A control circuit 10 calculates a flow rate of gas on the basis of a propagation time of the ultrasonic wave calculated on the basis of respective count values of the main counter and the sub counter.
