ABSTRACT:
An ultrasonic flow velocity measurement method and apparatus thereof and comprises ultrasonic wave transducers disposed on the upstream and downstream sides of a pipe and a control apparatus connected to these ultrasonic wave transducers. Concerning the flow velocity measurement, an average propagation sound velocity in the wedge which forms the ultrasonic wave transducers and the sound velocity on the surface where the wedge is brought into contact with the pipe are measured. The time from when ultrasonic waves are originated from the upstream side to the downstream side and and vice versa and to when they are received is measured. These measured values and the distance between the ultrasonic wave transducers are substituted for a predetermined function to determine the flow velocity of a fluid inside the pipe.
