Overview

  • The Aquadopp Profiler is a highly versatile Acoustic Doppler Current Profiler (ADCP) available in four profiling range options, from < 1 m to > 85 m. The 1 MHz version has a current profiling range of up to 25 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.

    This instrument is used to perform river discharge measurements by River Insight.

Highlights

  • Up to 25 m current profiling range
  • Optional right-angle head
  • PUV wave measurements

Applications

  • 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
  • Studies of deep-water currents
  • Studies of tidal currents
  • Measurements of combinations of waves and currents
  • Suitable for wave buoys
