Aquadopp Profiler 2 MHz

500 m, Generation 2

Small and compact, short-range current profiling; option for PUV wave measurements

  • Up to 10 m current profiling range
  • Optional right-angle head for measurements close to boundaries or in shallow water
  • Pressure-based (PUV) directional wave measurements

Overview

The Aquadopp Profiler is a highly versatile Acoustic Doppler Current Profiler (ADCP) available in three 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.

The upgraded Aquadopp Profiler design offers improved noise immunity as well as 6% broadband measurements and “hibernation mode” between measurements, enabling precise data collection with lower power consumption. Increased internal battery storage extends potential deployment time.

  • Waves

Highlights

  • Up to 10 m current profiling range
  • Optional right-angle head for measurements close to boundaries or in shallow water
  • Pressure-based (PUV) directional wave measurements
  • LED blinks when pinging for peace of mind during deployment

Usage

  • Near-bed current profiles with fine vertical resolution
  • Mean flow measurements with a focus on ease of use and simplicity
  • Measurements in areas with strong variations in flow speeds
  • Projects with needs for both high-resolution and normal-range current measurements with optional HR
  • Measurements of waves and currents from a single instrument
  • Studies of tidal currents

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.
