Solution Details

Urban Drainage Pipeline Flow and Velocity Online Monitoring System Solution

Urban drainage networks are critical infrastructure that directly impacts flood control and water environment management. Traditional manual inspection methods suffer from incomplete coverage, poor timeliness, and data gaps, failing to meet modern precision management requirements.

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 device integrates high-precision Doppler radar sensors with HD cameras, enabling a “see what you measure” visual monitoring approach. Combined with RTU remote telemetry terminals, it builds a complete drainage network online monitoring system.

The system is particularly suitable for municipal drainage pipelines, industrial park drainage networks, and critical nodes in combined sewer systems, providing precise data support for network operation scheduling, discharge permit supervision, and water environment governance.

The system is also essential at key nodes in combined sewer systems, providing data for overflow control and water environment governance.

Approach

How we implement intelligence into your infrastructure step by step.

Site Survey and Monitoring Point Layout

Conduct comprehensive drainage network investigation, identify critical monitoring nodes (trunk pipe junctions, outfalls, flood-prone points), and develop manhole installation plans

Equipment Selection and Manhole Installation

Select multi-band Doppler radar flowmeters based on pipe diameter and flow range, mount with dedicated brackets on manhole walls ensuring radar beam alignment with water surface

Communication Networking and Power Configuration

Configure RTU telemetry terminals at each monitoring point with 4G/5G network access to monitoring center, select from grid power, solar, or lithium battery based on site conditions

Platform Deployment and System Integration

Deploy drainage network monitoring cloud platform, integrate all monitoring point data, configure GIS maps, real-time trend charts, and alarm rules for end-to-end commissioning

O&M Management and Continuous Optimization

Establish regular inspection routines, remotely check equipment status via cameras, analyze network operation patterns from historical data to continuously optimize monitoring schemes
