radar flow meter

working principle

radar flow meterIt mainly consists of a radar flowmeter and a radar water level gauge. The flowmeter is used to collect the surface flow velocity of the fluid, and the average flow velocity of the cross section is calculated through a model. Combined with the water level and section information measured by the water level gauge, the cross section area of the cross section is calculated, and then the formula flow rate is used=The flow rate is obtained by multiplying the average flow velocity by the cross-sectional area and the correction factor, where the correction factor is calculated based on the standard value obtained from the actual measurement environment.

radar flow meterIntegrated radar water level gauge and radar current meter, with a radar water level gauge antenna beam angle of14 × 10 °, with a radar antenna angle of 14 × 32 °. When the water level gauge illuminates the water surface, the illumination area is similar to a circle, and when the flow meter illuminates the water surface, the illumination area is similar to an elliptical area. Accurately understanding the illumination range of the radar wave helps to choose the appropriate installation location and avoid some easily disturbed scenes, such as tree branches swaying with the wind on both sides of the river.
