Key features

Advanced Doppler Technology: Directly measures velocity profiles for nonuniform or reverse flow conditions without onsite calibration.

Versatile Application Range: Suitable for full/partially full pipes (150-6000mm) and open channels (200-10000mm width).

Non-Intrusive Measurement: Measures flow without touching liquid to reduce fouling, wear, and maintenance costs.

High Data Logging Capacity: Logs up to 16GB of data including level, velocity, flow, temperature, and conductivity.

Cost-Effective Installation: Single-sensor design eliminates need for flumes or weirs, significantly reducing installation costs.

Customizable for Harsh Environments: Built with rugged enclosures and flexible sensor options for outdoor, corrosive, or hazardous locations.

OEM/ODM Support: Full customization support including software reengineering and various model configurations.

Dual-Functionality Measurement: Combines Doppler velocity tracking with hydrostatic level measurement for accurate cross-sectional area.

Product Q&A

Q:What Are Open Channel Flow Meters?

Open Channel Flow Meters Are Specialized Instruments Designed To Measure The Flow Of Liquids In Channels, Streams, Or Partially Filled Pipes Where The Flow Is Not Under Pressure. Unlike Traditional Closed-Pipe Meters, They Determine Flow Rate By Calculating Both The Liquid Level And Velocity Using Separate Sensors. Typically Ultrasonic Or Electromagnetic For Velocity, And Any Level Technologies, For Level Measurement. These Meters Rely On Area-Velocity Measurement (AVM), Combining Data From Both

Q:How Open Channel Flow Meters Work?

Area Velocity Flow Meters Differ From Other Types By Combining A Velocity Sensor With An Ultrasonic Level Sensor To Calculate The Flow Rate. This Technology Offers Several Advantages For Certain Applications, Such As: * Accurate Flow Measurement In Partially Filled Pipes Or Channels With Irregular Shapes * Ability To Handle A Wide Range Of Flow Rates And Velocities * Reduced Installation Costs Compared To Flumes Or Weirs Open Channel Flow Meters Rely On Two Key Measurements To Determine The Flow
