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.

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

-
Studies of tidal currents
-
This instrument is used to perform river discharge measurements by River Insight.
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.
