Ocean currents

Aquadopp Profiler 1 MHz

Small and compact, with up to 25 m current profiling range; option for PUV wave measurements

概要

The Aquadopp Profiler is a highly versatile Acoustic Doppler Current Profiler (ADCP) available in four profiling range options, from < 1 m to > 85 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

ハイライト

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

使用法

  • 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

Setup

The 1MHz Aquadopp Profiler, 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.

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.
