2.Product Features
Non-Contact Radar Velocity Measurement
The Radar Velocity Meter adopts advanced microwave radar technology to measure surface water velocity without direct contact with water, eliminating the impact of sediment, debris, and water contamination on sensor performance.
High-Accuracy Flow Velocity Detection
Using Doppler radar measurement principles and intelligent signal processing algorithms, the device provides accurate and stable surface velocity measurements for rivers, channels, and open water applications.
Reliable Operation in Harsh Environments
The non-contact design allows stable operation under extreme conditions such as high sediment concentration, floating debris, strong currents, and fluctuating water levels.
Real-Time Continuous Monitoring
The system enables continuous velocity observation and automatic data acquisition, providing real-time information for hydrological analysis and water management.
Easy Installation & Low Maintenance
Without the need for underwater installation, the radar velocity meter can be installed above the water surface, reducing maintenance requirements and improving operational safety.
Flexible Integration with Monitoring Systems
Supports connection with RTU terminals, telemetry systems, and cloud platforms for remote data transmission, automated monitoring, and intelligent water management.
