Technical Description

The array radar on-line flow measurement system is a real-time on-line flow measurement system developed for wide-section river scenarios, which is suitable for natural rivers with a width of tens to hundreds of meters, or small and medium-sized rivers and channels with uneven cross-section flow velocity due to sluices and bends. The array radar online flow measurement system introduces multiple flow velocity sensors to obtain the flow velocity data of multiple velocity measurement verticals at the same time, so as to realize the accurate monitoring of water level, flow rate, flow rate and other information.

Working Principle

Features

Benefit: Effectively mitigates environmental interference, enhancing data reliability.

●   Non - Contact and Maintenance - Free

Feature: Based on proven radar current sensors; flexible installation via bridges, gantries, or cableways.

Benefit: Reduces construction, operational, and maintenance costs with minimal upkeep.

●   Safe and Reliable Flood Season Operation

Feature: Non - contact and unmanned solution during peak flood velocities and floating debris.

Benefit: Ensures safety and reliability in high - risk conditions, avoiding risks associated with contact - type methods.

• Why is the array radar system ideal for rivers with uneven flow distribution?​

  • Its ​multi-sensor array​ simultaneously captures velocity data across multiple verticals , overcoming flow distortions caused by bends, sluices, or irregular topography. This enables accurate flow calculations even in complex hydraulic conditions.

• How does this system achieve real-time flow monitoring in wide rivers?​

  • By integrating ​multiple radar velocity sensors​ with water level detection , it constructs a dynamic 3D flow profile. This allows continuous computation of key parameters (flow rate, cumulative volume) for sections spanning ​10–500 meters wide​ , with minimal manual intervention.
