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
