1.Portable open channel flow meter product introduction
Portable open channel flow meter is mainly based on measuring the water velocity and depth in the open channel, and then calculating the flow rate of the fluid.Portable open channel flow meter is a flow velocity and flow detection instrument used in rivers, open channels and pipelines. It uses ultrasonic detection technology, has high measurement accuracy, good stability, is less affected by environmental factors, has no rotating parts, has low maintenance frequency and high working reliability. It is the preferred product for portable flow velocity and flow measurement.
Applications: sponge cities, river chief management, inland river monitoring, natural rivers, open channels, pipelines, aquaculture and other scenarios.
Principle: The frequency difference between the transmitted and received ultrasound waves is related to the flow rate, and the time difference between the transmitted and received ultrasound waves is related to the liquid level. The static pressure liquid level is used for working conditions that require a large liquid level measurement range, and the ambient temperature measurement is used to correct the actual propagation speed of the ultrasound wave.
