Ultrasonic Flow meter is a device used to measure the velocity of the fluid with the help of ultrasound transducers to compute volume flow of the fluid. This flow meter measures average velocity of the fluid with the use of sound waves. Working Principle of Ultrasonic Flow Meters-.
Basic Principles of Ultrasonic Testing. Ultrasonic Testing (UT) uses high frequency sound energy to conduct examinations and make measurements. Ultrasonic inspection can be used for flaw detection/evaluation, dimensional measurements, material characterization, and more. To illustrate the general inspection principle, a typical pulse/echo inspection configuration as illustrated below will be used.
