Aquadopp Profiler 2 MHz

Petit et compact, pour les applications nécessitant une portée de mesure courte. Mesure de la houle par PUV en option.

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 2 MHz version has a current profiling range of up to 10 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.

  • Currents
  • Waves

Highlights

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

Usage

  • 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

Setup

The 2MHz Aquadopp Profiler, designed for current measurements in shallow water (offering a 10m profiling range), is set up using the Nortek deployment software, enabling users to customize measurement schemes and assess power requirements.

Deployment

Compact size and an optional right-angle head allow for very near-bed deployments, maximizing water column coverage in shallow areas. Teams of all sizes can deploy an Aquadopp Profiler successfully.

Data

Nortek postprocessing software and/or display software is available for review, visualization, and processing of data, after deployment or in real time.
