Setup
The 400kHz Aquadopp Profiler, designed for straightforward current measurements at up to a 90m range, is set up using the Nortek deployment software, enabling users to customize measurement schemes and assess power requirements. It offers the longest profiling range of the Aquadopp Profiler family.
Deployment
Teams of all sizes can deploy an Aquadopp Profiler successfully thanks to its compact size and flexible deployment options. Buoy, bottom frame and inline setups from Nortek and leading industry partners are available specifically for the instrument.
Data
Nortek postprocessing software and/or display software is available for review, visualization, and processing of data, after deployment or in real time.
