Doppler In Line Pipe Type Ultrasonic Flow Meters For Waste Water Treatment

Principle of operation

This doppler inline ultrasonic flow meter, employs the frequency shift, that's the Doppler Effect, of an ultrasonic signal when it is reflected by suspended particles or gas bubbles (can be discontinusely) in motion. A metering technology uses the physical phenomenon of a sound wave which changes frequency when it is reflected by the moving discontinuities in a flowing liquid. The ultrasonic sound is transmitted into a pipe with flowing liquids, and the discontinuities reflect the ultrasonic wave with a slightly different frequency that is directly proportional to the rate of flow of the liquid (Figure 1). Current technology requires that the liquid contain at least 100 PPM of 100 micron or larger suspended particles or bubbles.
