DEVELOPMENT OF AN ULTRASOUND VELOCITY PROFILE MONITOR

An ultrasound velocity profile (UVP) monitor has been developed. It utilises a pulsed echographic ultrasound technique and can instantaneously measure a velocity profile along one line in a vector form. The principle and characteristics of the method and the developed systems are described. The results of confirmation experiments have proved that the method measures the velocity profile to high accuracy (5% for velocity and 1% for position). Applications in various configurations demonstrate its efficiency for obtaining spatial information about flow structures as well as its effectiveness in measuring flow in liquid metals.
