Handheld Doppler Ultrasonic Flow Meter

Product Description Product Introduction Of Doppler Flow Meter (Handheld Type) DF6100-EH Handheld Doppler Ultrasonic Flow Meter Series DF6100-EH Doppler Handheld Ultrasonic Flow Meter is designed to measure volumetric flow of within closed conduit, the pipe line must be full of liquids, and there must be a certain amount of air bubbles or suspended solids in liquid. The Doppler ultrasonic flow meter can display flow rate and flow totalizer, etc., and is configured with 4-20mA, OCT outputs. Working Principle Of Doppler Flow Meter 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. 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 10 D and downstream needs 5 D straight pipe length, where D is pipe diameter.
