摘要： PROBLEM TO BE SOLVED: To reduce a cost, to lower electric current consumption, and to prevent troubles due to secular change of a vibrator in a reference clock generator for measuring arrival-requisite time (propagation time) of an ultrasonic, in the case of an ultrasonic flowmeter.
SOLUTION: In a fluid, the ultrasonic is transmitted/received in a forward direction successively and repeatedly a plurality of times (n times) to measure total arrival-requisite time by a reference clock. Total arrival-requisite time in the forward direction is measured likewise. Flow velocity and flow volume are found from the two kinds of arrival-requisite time. The reference clock is oscillated while the arrival-requisite time is measured, and stopped when the measurement is completed. A frequency output of the reference clock is counted for time T2 on the basis of a second reference clock using crystal oscillation at a control part. When a count value obtained by the counting stands outside a prescribed scope, a deviation is determined to be large and an alarm is issued by blinking a display part.

摘要： PROBLEM TO BE SOLVED: To provide a flowmeter in which a life time of a battery i.e. a power source is made predictable. SOLUTION: A flow measuring part 4 intermittently measures an instant flow rate of a fluid passing through a conduit 11. A pulsation determination means 5b equipped in a controller 5 monitors the presence of a pressure pulsation. When the pressure pulsation is detected, a mode selecting means 5a indicates the flow measuring part 4 that a time interval for measuring the instant flow rate is to be shorter than that when no pressure pulsation is detected. A measuring interval integrating means 5e integrates in a memory 7 both the time intervals when the pressure pulsation is detected and not detected, and a battery consumption operating means 5d calculates product of each interval and its corresponding unit electricity consumption and calculates a grand sum as a battery consumption. A presentation means 5f presents the battery consumption to a manager through a network. COPYRIGHT: (C)2004,JPO
