Overview-Ultrasonic Flowmeter

Ultrasonic flowmeters are highly useful in a variety of applications across multiple industries.
No moving parts in ultrasonic flowmeters, Since ultrasonic flowmeters don’t involve moving parts, they last a long time with very little maintenance. As long as the meter is properly mounted and installed, these meters are highly accurate.
However, inline and insertion flowmeters are generally more accurate than clamp-on ultrasonic flowmeters.

Ultrasonic flowmeter Principle

An ultrasonic flow meter construction can be done by using upstream and downstream transducers, sensor pipes, and reflectors. The working principle of the ultrasonic flow meter is, that it uses sound waves to resolve the velocity of a liquid within a pipe.
Whenever the liquid flows in the pipe quickly, then the frequency shift can be increased linearly. The transmitter processes the signals from the wave & its reflections determine the flow rate. Transit time meters transmit & receive ultrasonic waves in both directions within the pipe. At no-flow conditions, the time taken to flow between upstream & downstream in between the transducers is the same.
