What is a Ultrasonic Flow Meter?

Ultrasonic flow meter measures fluid velocity by passing high-frequency sound waves along the fluid flow path.

Transit time and Doppler Ultrasonic Flow Meters are two very popular types of flow meter for non-invasive measurement of flow in full pipes.

Ultrasonic flow meters operate using difference in time travelled by the two ultrasonic waves is directly proportional to the flow velocity.
