Portable Doppler Ultrasonic Flow Meter Flowmeter

详情

  The Doppler ultrasonic flow meter is designed to measure the flow, there must be a certain amount of air bubbles or suspended solids in liquid. within closed conduit, the pipe line must be filled full of liquids. 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.

The doppler flowmeter could work for the monitor of Raw sewage, Return activated sludge, Waste activated sludge, Ground water, Pulp and paper slurries, Chemical slurries, Drainage, Mining recirculation.
