Instrument Overview

The Doppler shift method is used to obtain 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 discharge rates in various types of channels—open channels, riverbeds, sewers, drainage networks, and other conduits—whether they are fully or partially filled.

Performance Features

1. The IP68 integrated telemetry terminal can be submerged for extended periods.
2. Built-in lithium-ion battery and 4G transmission module
3. Remote parameter tuning, with automatic data storage
4. Ultra-large-capacity 266Ah lithium-thionyl chloride battery
