Aquadopp Profiler 2 MHz

Small and compact, short-range current profiling; option for PUV wave measurements

Technical specification (PDF)


  • Up to 10 m current profiling range
  • Optional right-angle head
  • PUV-based directional wave measurements


  • The Aquadopp Profiler is a highly versatile Acoustic Doppler Current Profiler (ADCP) available in four profiling range options, from < 1 m to > 85 m. Designed for simple yet powerful operation, this current profiler is packed with features used by engineers and researchers to enable accurate and effective hydrodynamic data collection in a variety of environmental conditions.


  • Near-bed current profiles with fine vertical resolution
  • Mean flow measurements with high focus on ease of use and simplicity
  • Measurements in flow regimes with strong variations in flow speeds
  • Projects with needs for both high-resolution and normal-range current measurements
  • Measurements of combinations of waves and currents
  • Studies of deep-water currents
  • Studies of tidal currents
  • Mounted on surface buoys
  • Suitable for wave buoys
  • Water velocity measurements
