摘要： PROBLEM TO BE SOLVED: To provide an ultrasonic flowmeter capable of absorbing pulsation by simple structure improvement without large modification or without requiring an electronic circuit for performing complicated correcting calculation.
SOLUTION: The ultrasonic flowmeter comprises a measuring tube 6 arranged in a fluid passage 11, and a pair of ultrasonic transmitter-receivers 5 arranged so that ultrasonic waves propagate in the measuring tube diagonally crossing the central axis of the measuring tube. The ultrasonic flowmeter transmits and receives ultrasonic waves between the pair of ultrasonic transmitter-receivers, measures the propagation time of the ultrasonic wave in the forward direction and backward direction of the flow of fluid, and calculates the flow rate of the fluid based on the difference of the measured propagation time. The ultrasonic flowmeter has a fluid resistor 10 in at least one of the upstream-side passage and the downstream-side passage of the measuring tube 6.
