Radar Open Channel Flow Meter

The Radar Open Channel Flow Meter is a non-contact flow measurement instrument that uses microwave radar technology to simultaneously measure water surface velocity and water level in open channels. Using the Doppler effect principle, it transmits microwave signals toward the water surface and analyses the reflected signals to determine surface velocity. Combined with continuous level measurement and channel cross-section parameters, it calculates real-time flow rate accurately without any contact with the liquid.

Key Features:
- Non-contact radar measurement — no direct contact with liquid
- Simultaneous surface velocity and water level measurement
- Real-time flow rate calculation using built-in software algorithm
- Not affected by corrosion, sediment, water plants, or floating debris
- 4-20mA analogue output for control system integration
- SCADA compatible with data logging capability
- Panel mount display for local monitoring
- Flow range 0 to 500 m³/hr
- Power supply 230V AC
- Suitable for rectangular, trapezoidal, triangular, U-shaped, and irregular channel sections
- Easy to install on existing structural parts such as bridges, beams, and metal poles
- No moving parts — minimal maintenance and long service life
- Suitable for solar power operation due to low power consumption
- Antenna must be mounted with speed detection sensor directed opposite to flow at angle less than 60° to flow direction
- Level sensor mounted perpendicular to water surface

Applications:
- Rivers and natural waterways flow monitoring
- Irrigation canal water metering
- Underground drainage network monitoring
- Municipal sewage and wastewater flow monitoring
- Flood control and early warning systems
- Reservoir gate flow monitoring
- Water conservancy and water resource management
- SCADA-integrated remote water monitoring stations
