Product Overview


Product Description

Clamp on handheld Doppler flow meter

Rechargeable battery can work up to 14 hours
It is suitable for pipe sizes ranging from 40 to 4000mm
For dirty liquids, a certain amount of air bubbles or suspended solids shall be contained
Excellent low flow rate measurement ability, low to 0.05m/s
A wide range of flow measurement, high flow rate can reach 12m/s
High-temperature transducer is suitable to liquids of -35℃ ~ 200℃
Do not need to shut down the pipe flow when installing the transducers
User-friendly configuration
4-20mA, Relay Totalizer and Relay Alarm outputs
Accuracy: 2.0% Calibrated span

Working Principle

The working principle of Doppler frequency shift is used to measure the velocity of water flowing.
The ultrasonic flowmeter operates by transmitting an ultrasonic sound from its transmitting transducer,the sound will be reflected by useful sonic reflectors suspended within the liquid and recorded by the receiving transducer. If the sonic reflectors are moving within the sound transmission path, sound waves will be reflected at a frequency shifted(Doppler frequency) from the transmitted frequency.The shift in frequency will be directly related to the speed of the moving particle or bubble. This shit in frequency.
There must be some particles large enough to cause longitudinal reflection - particles larger than 100 micron.
When install the transducers,the installation location must have enough straight pipe length upstream and downstream. Commonly, the upstream needs 10D and downstream needs 5D straight pipe length, where D is pipe diameter.
