Fixed Type Dopper Flowmeter


Fixed installing wall mounted ultrasonic doppler flow meters with clamp-on transducers or insertion transducers.

More details


Fixed Type Dopper Flowmeter

 

Dopper flow meter uses non-invasive doppler ultrasonic technology for liquid flow measurement and no need to cut pipes.The doppler flow meter is fixed installing for long-term online monitor and measurement.The suspended solids or bubbles in medium should be over 0.1% (bigger than 0.1 microns.

In order to meet different requirement, we also develop insertion transducer for the doppler ultrasonic flow meters.
