Ultrasonic Doppler Flow Meter (Miniature)

The Doppler shift technique is used to obtain flow velocity. The measurement point is located diagonally above 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 discharge rates in various types of channels—open channels, riverbeds, sewers, drainage networks, and other conduits—whether they are fully or partially filled.
