How does Doppler radar flowmeter work with water level gauge for accurate open channel flow measurement?
Doppler radar flowmeter with water level gauge measures flow via velocity × area calculation for accurate non-contact open channel measurement
The combination of Doppler radar flowmeter and water level gauge provides the most accurate solution for open channel flow measurement. Ecolor Technology's HZ-KSLF multi-band Doppler radar flowmeter uses non-contact measurement principles, transmitting microwave signals to measure water surface velocity, while working with visual radar water level gauge using FMCW technology for precise water level measurement.
System operation principles include:
- Radar flowmeter measures surface velocity with ±3% accuracy
- Radar level gauge simultaneously measures water level changes with ±2mm precision
- Built-in algorithms calculate cross-sectional flow area
- Flow rate = velocity × cross-sectional area for real-time calculation
Combined with EC32 series RTU remote terminal, the system enables 4G wireless transmission and solar power supply, suitable for rivers, channels, irrigation areas and various hydraulic engineering applications, providing reliable data for flood warning and water resource management.
