Overview

  • The Aquadopp Profiler is a highly versatile Acoustic Doppler Current Profiler (ADCP) available in four profiling range options, from < 1 m to > 90 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.

Highlights

  • Up to 90 m current profiling range
  • Ideal for mean current measurements
  • Easy to operate and deploy

Applications

  • Mean flow measurements with high focus on ease of use and simplicity
  • Measurements in flow regimes with strong variations in flow speeds
  • Studies of tidal currents
  • Measurements of combinations of waves and currents
  • Mounted on surface buoys
  • Suitable for wave buoys
