What is Ultrasonic Flow Meter ?
Ultrasonic flow meter measure fluid velocity by passing high-frequency sound waves along the fluid flow path. Fluid motion influences the propagation of these sound waves, which may then be measured...

Difference between Transit time and Doppler Ultrasonic Flow Meter
Doppler and transit time are two very popular types of flow meter for non-invasive measurement of flow in full pipes. These technologies are often confused, because they are both ultrasonic,...
Basics of Ultrasonic Flow meters & Factors Affecting its Performance
The term ultrasonic is used to describe pressure waves at frequencies higher than the human ears can detect. The velocity of the sound waves in the fluid is the same...
Ultrasonic Flow Meters Working Principle
Ultrasonic flow meters operate using the transit-time differential method. The Transit-time differential measurement is based on a simple physical fact. Imagine two canoes crossing a river on the same diagonal...
