Horizontal Acoustic Doppler Current Profiler

The Horizontal Acoustic Doppler Current Profiler (H-ADCP) is an instrument designed for long-term, unattended monitoring. It is typically installed on shore walls or bridge piers and is widely used in applications such as river flow velocity and discharge monitoring, flow velocity and discharge monitoring in large open channels, flood warning systems, environmental handover section monitoring, and water diversion projects.
