This system is designed for wide river channels, bridges, and open water flow monitoring applications, including:

• Medium: natural river water / surface flow
• Environment: outdoor open channels, bridge sections, flood-prone areas
• Installation conditions:
  • Wide cross-section rivers with uneven velocity distribution
  • High humidity, rain exposure, and seasonal flood conditions
  • Remote locations with limited power access

Suitable for hydrology monitoring, flood warning, and water resource management systems

In wide river flow measurement projects, traditional methods often fail due to:

• Uneven flow velocity across different river sections
• Single-point measurement leads to low accuracy
• Manual measurement is dangerous during high water levels
• Difficult to obtain continuous real-time data
• Power supply and remote data transmission challenges
• Poor reliability in flood or extreme weather conditions

Result: flow calculation errors, weak flood prediction capability, and data gaps

We provide a multi-point radar flow monitoring system based on velocity–area method, including:

• Radar Velocity Sensors (Multi-point Deployment)
  • Non-contact surface velocity measurement
  • Installed at multiple positions across river width
  • Captures velocity differences in different flow zones
• Radar Water Level Sensor
  • Installed on bridge or riverbank structure
  • Measures real-time water level changes
  • Works under rain, fog, and turbulence conditions
• Data Integration Terminal Unit (RTU)
  • Collects data from multiple velocity sensors + water level sensor
  • Performs velocity-area flow calculation
  • Outputs real-time flow rate

Core method: Velocity–Area Flow Calculation Model

• Power Supply Options
  • Municipal power supply
  • Solar-powered autonomous system for remote sites

• Radar velocity sensors:
  • Installed across different sections of river width (multi-point layout)
  • Fixed on bridges, poles, or cable suspension systems
• Radar water level sensor:
  • Installed on bridge underside or riverbank structure
  • Facing water surface vertically
• RTU data unit:
  • Installed in control cabinet or waterproof outdoor box

Designed for long-term unattended operation

After deployment of the system:

• Significantly improved flow measurement accuracy
• Multi-point velocity sampling reduces single-point error
• Real-time flow data acquisition achieved
• Improved flood warning and early response capability
• Reduced manual field measurement risk
• Higher reliability compared with single velocity station systems

Especially suitable for complex wide-channel hydraulic environments

This solution includes:

• Radar surface velocity meter (multi-point system)
• Radar water level sensor
• Remote Terminal Unit (RTU) data collector
• Solar power supply system (optional)
• Wireless / 4G data transmission module
• Velocity-area flow calculation software

Traditional single-point flow measurement assumes uniform velocity, which is not realistic in wide rivers.

• Measuring velocity at multiple cross-sectional points
• Combining with water level data
• Calculating flow using velocity-area integration method

This provides much higher accuracy for wide river channels

We provide:

• Site-specific layout design (bridge / river width planning)
• Sensor positioning recommendation
• Flow calculation model setup
• Solar + remote deployment support
