Non-Contact Radar Flow Meter for River & Open Channel Flow Monitoring
High-Precision Discharge Measurement System for Hydrology, Irrigation, and Flood Control
Product Manual (pdf)
Product Introduction
The KH.UOCF Non-Contact Radar Flow Meter is an advanced hydrological monitoring system designed for real-time measurement of water level, surface velocity, and discharge (flow rate) in rivers, canals, reservoirs, and open channels.
Unlike traditional mechanical flow meters or contact-based sensors, this system uses microwave radar technology to perform non-contact measurement of both water level and surface velocity, enabling continuous and stable flow monitoring in complex natural environments.
It is widely used in river hydrology stations, irrigation canal networks, flood forecasting systems, and smart water resource management platforms, providing critical real-time data for water allocation, flood prevention, and environmental decision-making.
How It Works
The system continuously measures:
- Water surface level (radar-based non-contact measurement)
- Surface flow velocity (microwave Doppler-based detection)
These two parameters are processed through hydrological algorithms to calculate real-time discharge (flow rate).
This approach ensures:
- No mechanical contact with water
- No blockage from sediment or floating debris
- Stable long-term performance in natural river conditions
