る超音波流速流量計。 A pair of tubes that are attached to a tube through which fluid flows so as to face each other while being inclined in the flow direction of the fluid, and that transmit and receive ultrasonic signals to measure the flow rate or flow rate of the fluid flowing through the tube. In an ultrasonic flow rate meter equipped with an ultrasonic transducer unit, parallel lines where the center lines of the ultrasonic waves respectively emitted from the pair of ultrasonic transducers intersect at positions spaced apart from each other on the center line of the tube body. An ultrasonic flow rate meter characterized by:
