Aquadopp Profiler Z-Cell 2

1 MHz

Jusqu'à 25 m de mesure de profil de courant et sans zone blanche. Permet de mesurer proche du fond ou en proche surface

Aperçu

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.

  • Currents
  • Waves

Points forts

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

Utilisation

  • 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

Setup

The 1MHz Aquadopp Z-Cell, designed for current measurements up to a 25m range, is set up using the Nortek deployment software, enabling users to customize measurement schemes and assess power requirements. The Z-cell functionality allows measurements at the level of the instrument head, eliminating the “blanking distance” at which most ADCPs cannot measure.

Deployment

Teams of all sizes can deploy an Aquadopp Z-Cell successfully thanks to its compact size. The instrument is optimal for deployments near boundaries such as the seabed or sea surface.

Data

Nortek postprocessing software and/or display software is available for review, visualization and processing of data, after deployment or in real time. The instrument can provide data from the level of the instrument as well as a full water column profile.
