HOH-L-03 small radar flowmeter

1Equipment Composition

IIEquipment principle

The radar current meter measures the surface velocity of the water flow, and the radar water level gauge measures the water depth. By inputting the cross-sectional dimensions in advanceUtilizing HydraulicsThe model calculates the cross-sectional flow rate. Radar flow meters are divided into two types: integrated and split. The integrated type includes a radar water level gauge, a radar flowmeter, and a terminal unit (RTU) integrated into one.
