Abstract

PURPOSE:To utilize the fact that the time required for ultrasonic pulses to propagate between the ultrasonic transducers provided on the uptstream and downstream sides of a flow line for fluid to be measured is affected by the velocity of flow, thereby measuring the velocity of flow of the fluid at high accuracy.
