Rapid Delivery for Open Channel River Water Radar Flow Meter Flood Velocity Meter

The Radar Velocity Meter is an integrated device combining a microstrip antenna, RF circuit, and signal processing unit. It directly outputs target velocity information and is used for flow velocity measurement in rivers and underground pipeline networks.

The radar adopts an imported German integrated chip and a front-end low-noise amplifier, featuring ultra-high sensitivity. It measures surface water flow velocity based on the Doppler principle. The microwave radar is not affected by temperature, pressure, air density, wind, or other environmental conditions, enabling stable all-weather and all-time operation.

Our radar velocity meter features a low starting speed and a wide measuring range. It includes built-in tilt compensation and gain adjustment, making installation simple and convenient. The product is widely used for monitoring surface flow velocity in rivers, open channels, and underground culverts. When combined with a water level gauge, it can form an online flow monitoring system.

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.

Product Uses

  • Measure surface water velocity in rivers, channels, and open water bodies.
  • Monitor real-time flow velocity changes for hydrological observation.
  • Provide flow velocity data for discharge calculation and water resource management.
  • Support flood monitoring and early warning systems.
  • Collect long-term flow data for hydraulic analysis and research.
  • Enable automatic and remote flow monitoring without manual measurement.
  • Integrate with water level sensors to achieve comprehensive flow measurement.

Product Applications
