Ultrasonic Doppler Flow Meter (Dual Water Level)

The Doppler shift technique is used to measure flow velocity. The measurement point is located directly in front of the device, ensuring no disturbance to the flow field. This method offers high accuracy and linear measurement capabilities, enabling the determination of both instantaneous and average flow velocities. It is suitable for monitoring water levels, flow velocities, and flow rates in various types of channels—such as open channels, riverbeds, sewers, and drainage networks—whether the pipes are fully or partially filled.

Instrument Overview

The Doppler shift method is used to measure flow velocity. The measurement point is located directly in front of the device, ensuring no disturbance to the flow field. This method offers high accuracy and linear measurement capabilities, enabling the determination of both instantaneous and average flow velocities. It is suitable for monitoring water levels, flow velocities, and flow rates in various types of conduits—whether fully filled or partially filled—including open channels, riverbeds, sewers, and drainage networks.
