ABSTRACT:
An ultrasonic flowmeter arranged to perform measurement with high accuracy has first and second ultrasonic transducers1, 2which transmit and receive ultrasonic waves, and which are placed so as to form a path for propagation of the ultrasonic waves in a flow passage14for a fluid, a transmitting section3which drives one of said first and second ultrasonic transducers1, 2,a first matching section5which is connected to the transmitting section, and which adjusts the output impedance of the transmitting section, and a receiving section6which has an input impedance approximately equal to or lower than the adjusted output impedance, and which receives the ultrasonic wave reaching the other of the first and second ultrasonic transducers. The flow volume of the fluid is measured by detecting a bidirectional-propagation time difference between the ultrasonic waves propagating in the propagation path.
