Open Channel Flow Monitoring System Solution

Open channels, as common water conveyance channels in nature and hydraulic engineering, are widely found in rivers, irrigation canals, urban drainage networks, and other scenarios. Accurate monitoring of their flow is a crucial foundation for rational water resource allocation, flood control and drought relief decision-making, and hydraulic engineering management. The Open Channel Flow Monitoring System can measure water flow in open channels in real-time, providing reliable data support for water resource measurement, water usage scheduling, and ecological protection. It is a key technological equipment for achieving refined water resource management.

Approach

How we implement intelligence into your infrastructure step by step.

Site Survey & Requirement Confirmation

Investigate open channel cross-section shape, flow conditions (velocity range, water level fluctuation), and water quality characteristics (sediment content, corrosiveness). Clarify requirements for monitoring accuracy, data reporting frequency, and alarm thresholds. Determine installation points and assess power supply and communication conditions.

Solution Design & Equipment Selection

Select appropriate Doppler flowmeter model. Determine installation method (bracket wall-mounting, channel bottom fixing, bridge suspension). Design power supply solution (solar + battery) and communication solution.

Equipment Installation & Commissioning

Install Doppler flowmeter probe, adjusting its immersion depth and angle. Connect data acquisition terminal to power supply and communication modules. Power on to test probe signal strength, calibrate velocity measurement zero point, and input open channel cross-section parameters.

System Integration & Data Verification

Establish data link from "probe - acquisition terminal - cloud platform". Test data transmission stability. Compare with standard flow measurement data to correct flow calculation model parameters. Configure alarm thresholds and simulate flow exceedance scenarios to verify alarm notification functionality.

Trial Operation & Optimization

Conduct 1-2 weeks of trial operation, covering different conditions such as sunny/rainy weather and high/low water levels. Monitor equipment operation status, troubleshoot issues like data deviation and communication interruption. Optimize probe installation position and parameter configuration to improve measurement accuracy.
