Overview
The Aquadopp 500 m is a compact, accurate and affordable single-point current meter for applications where a current profile is not needed. Designed for use in several deployment scenarios, from mooring lines to bottom-mounted structures, it also has the option to perform PUV-based directional wave measurements, making it a cost-effective and simple solution.
The Aquadopp now offers 6% broadband measurements and “hibernation mode” between measurements, enabling precise data collection with lower power consumption. Combined with mechanical improvements allowing for more internal battery storage, the modern Aquadopp design extends potential deployment duration.
See the details of the Generation 2 Aquadopp updates in the release notes here.

Setup
Nortek deployment software allows users to customize their 500m Aquadopp current meter deployment in a straightforward manner, providing guidance on deployment schemes, battery power and required internal memory.
Deployment
The Aquadopp is the ideal current meter for an ADCP mooring, but it is also compatible with bottom- or buoy-mounted setups. Teams of all sizes can successfully deploy an Aquadopp thanks to its compact size and ability to run entirely on internal battery power.
Data
Nortek postprocessing software and/or display software is available for review, visualization, and processing of data, after deployment or in real time.
