Product description
Ultrasonic open channel flowmeter is a kind of high-precision flow meter that uses ultrasonic to measure Venturi channel or Parshall groove. It measures the time for the sound wave to reflect back after touching the water surface of the channel, and then calculate the flow rate of the channel according to the formula, which can provide flow output,Display flow rate and total flow.
