製品概要:
Surface velocity and laminar velocity
This product is a fully automatic flow meter based on microwave technology. It uses K-band flat-panel radar technology and combines the positioning function of frequency modulated continuous wave (FMCW) radar to accurately measure water level. It combines radar flow velocity and the Doppler effect of water body at relative speed to obtain the flow velocity of the measured object. Through the relationship between water level, water cross-sectional area, surface velocity and laminar velocity, to calculate the water flow section and flow rate. It is widely used in the flow velocity and flow monitoring of water conservancy and hydrological projects.

応用：
Urban waterlogging monitoring: In urban waterlogging, road waterlogging, and flood control, radar flow meters can monitor water levels and flow rates, providing a basis for the management and optimization of urban drainage systems.
Hydrological monitoring: Radar flow meters can be used for hydrological monitoring of natural water bodies such as rivers, reservoirs, lakes, and rivers. Real-time monitoring of water velocity, water level, and flow provides strong support for water resource management and flood prevention and disaster reduction.
Open channel flow monitoring: In the main channel, branch channel and other open channels of the irrigation area, radar flow meters can realize real-time monitoring of flow and provide data support for water resource scheduling and management of the irrigation area.
