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.
Suitable to measure the flow of solids-bearing or aerated liquid within closed conduit
Excellent low flow rate measurement ability, low to 0.03 m/s
Automatically signal gain adjustment
Regardless of the clamp-on type or insertion type, don't need to shut down the pipe .
flow when install the transducers.
4-20mA and totalizer pulse output
Accuracy: 2.0% Calibrated span
The Clamp-on, non-contacting transducers are strapped to the outside of a pipe and are suitable for most installations where the pipe material supports the transmission of ultrasound.
