ESMTUF2000F External clamp type acid-base solution non-contact measurement ultrasonic flowmeter
Working Principle
The time-difference method is usually used, where an external clamp-on sensor emits and receives ultrasonic waves, measures the difference in propagation time of the ultrasonic waves in the fluid in the downstream and upstream directions, and then calculates the fluid flow velocity. Combined with parameters such as the pipe's cross-sectional area, the flow rate can be determined.
Product Features
- No need to break the pipeline or stop production;
- the sensor does not come into contact with the measured medium
- causes no pressure loss.
