Solution Details

Drainage Pipeline Flow and Velocity Online Monitoring System Solution

The Drainage Pipeline Flow and Velocity Online Monitoring System Solution provides real-time, non-contact monitoring for urban drainage networks, delivering critical data for flood control and water environment management. This advanced solution overcomes the limitations of traditional manual inspections by offering continuous, precise, and visual oversight of pipeline conditions.

Overcoming Traditional Monitoring Limitations

Urban drainage networks are vital infrastructure that directly impacts flood control and water environment management. Traditional manual inspection methods suffer from incomplete coverage, poor timeliness, and data gaps.

These outdated approaches fail to meet modern precision management requirements for municipal and industrial drainage systems, creating a need for automated, reliable online monitoring.

Core System Technology and Components

This solution deploys multi-band Doppler radar flowmeters inside drainage manholes for real-time non-contact monitoring of pipeline flow rate, velocity, and water level. The integrated device combines high-precision Doppler radar sensors with HD cameras.

This enables a unique “see what you measure” visual monitoring approach, providing both quantitative data and visual verification. Combined with RTU (Remote Telemetry Unit) terminals, it builds a complete drainage network online monitoring system for comprehensive oversight.

Key Application Scenarios for Pipeline Monitoring

The drainage pipeline monitoring system is particularly suitable for municipal drainage pipelines, industrial park drainage networks, and critical nodes in combined sewer systems. It provides essential data for network operation scheduling and capacity management.

This solution offers precise data support for discharge permit supervision and overall water environment governance, helping authorities and operators make informed decisions based on real-time flow and velocity data.
