Two piezoelectric transducers, acting as transmitter and receiver alternately, are mounted on opposite outside of the pipe at a fixed axial separation, and ultrasonic waves are transmitted simultaneously in opposite directions from one to the other The component of flowing velocity along the acoustic path adds to the acoustic velocity in the downstream direction but subtracts in the upstream direction, thus making the upstream transit time larger than the downstream transit time.
