Highlights

  • Up to 25 m current profiling range
  • Capable of measuring surface or bottom currents
  • PUV-based directional wave measurements

Overview

  • Need to collect accurate 3D currents very near the seabed or sea surface, in addition to a full water-column profile?

    The Z-Cell (Zero Cell) Aquadopp allows current measurement to start right at the instrument’s level through an innovative approach: it has side-looking beams fully integrated into the instrument’s head, effectively removing the blanking distance normally applicable to ADCPs.

Applications

  • Mounted on bottom frames, with ability to measure also near-bed currents
  • 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 tidal currents
  • Measurements of combinations of waves and currents
  • Mounted on surface buoys, with the ability to measure also surface currents
