The Series UFX utilizes two piezoelectric crystals contained within one transducer to transmit ultrasonic energy into the fluid stream and receive reflected energy off discontinuities, suspended particles or entrained gases, within the moving liquid. When the fluid is fl owing in the pipe (with the discontinuities traveling at the same speed), there will be an apparent shift in frequency from the transmitted sound wave to the received sound wave. The difference between these sound wave frequencies is the Doppler frequency shift and is proportional to fluid velocity. In addition to measuring and displaying fluid velocity, the UFX processor also controls all operations of the instrument from its ultra-efficient battery management circuitry to a proprietary FIR (Finite Impulse Response) filtration program.
