Overview

  • The 2D Horizontal Profiler is the ideal tool for current measurements from a physical structure in, for example, port entrances. This ADCP provides the two horizontal flow components at multiple distances from the mounting and is commonly used in online applications where immediate access to current data is critical.

Highlights

  • Up to 130 m horizontal profiling range
  • Ideal for wall-mounted applications
  • Corrosion-free housing

Applications

  • Port entrances with challenging flow conditions
  • Flow measurements upstream and downstream of tidal turbines
  • Flow measurements from marine structures at draft depth
