FRM6000 Open Channel River Radar Flowmeter

The open channel flow meter is mainly composed of a radar flow meter and a radar water level meter. The flow meter is used to collect the surface velocity of the fluid, and calculate the average flow velocity of the cross section through the model calculation, and then calculate the cross section area by combining the water level measured by the water level meter and the cross section information. Thus use the formula flow rate average flow velocity cross sectional area correction coefficient to obtain the flow rate, wherein the correction coefficient is calculated according to the standard value obtained in the actual measurement environment.
