Portable open channel flow meter

1. Product introduction of Portable open channel flow meter

Portable open channel flow meter uses the principle of the Doppler effect to provide flow and velocity measurement for rivers and open channels.Portable open channel flow meter is a flow rate and flow detection instrument used in rivers, open channels, pipelines and other working conditions. It uses ultrasonic detection technology, has high measurement accuracy, good stability, is less affected by environmental factors, has no rotating parts, low maintenance frequency, and high working reliability. It is the first choice for portable flow rate and flow measurement.

Application: Sponge city, river chief system management, inland river monitoring, natural rivers, open channels, pipelines, breeding and other scenarios.

Principle: The frequency difference between transmitting and receiving ultrasonic waves is related to the flow rate. The time difference between ultrasonic transmitting and receiving is related to the liquid level. The hydrostatic liquid level is used in working conditions that require a large liquid level measurement range. The ambient temperature measurement is used for correction. The actual propagation speed of ultrasonic waves.
