Principle of Measurement:
The Doppler ultrasonic flow meter is designed to measure volumetric flow of liquid within closed conduit, the pipe line must be filled full of liquids, there must be Ta certain amount ofT air bubbles or suspended solids in liquid.
Transducers are clamp-on or hot-tapped probe types, user don’t need to shut down the pipe flow when install the clamp-on transducers.
The flow meter 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 shift in frequency is interpreted by the instrument and converted to various user defined measuring units.
Features:
1,Suitable to measure the flow of solids-bearing or aerated liquid within closed conduit
2,Automatically signal gain adjustment
4,Don't need to shut down the pipe .
5,Flow on when install the transducers.
