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-.
Ultrasonic frequency is defined as the frequency of an acoustic wave at a frequency above the audible range for humans. This system operates at a base frequency of 40,000 cycles per second or 40 kilohertz (kHz). Due to the design of the âVibra-barâ transducer âSimultaneous Multi-Frequencyâ is produced.
