The 350 Ex sensor continuously transmits an ultrasonic signal into the flow stream. The signals are reflected off bubbles and solids and return to the sensor with a frequency shift (Doppler effect) which is translated into velocity. A differential pressure transducer in the sensor measures liquid depth to determine the wetted area.
Flow rate is then calculated by multiplying the wetted area of the flow stream by its average velocity. Certified to MCERTS when paired with a Signature flow meter.
