  • Low-pressure loss
  • Integrated and configurable totalizer function


Technical Data

Two piezoelectric transducers, mounted in the sensor housing, generate and receive an ultrasonic wave. The wave going in direction of the flow (with-stream wave) is accelerated and the wave going against the flow direction (against-stream wave) is slowed down. The two waves are processed by a signal converter. The difference in the transit time of both waves is proportional to the velocity of the fluid.
