Capabilities

How does Eco work?

  • The Nortek Eco is a portable Acoustic Doppler Current Profiler (ADCP).
  • The instrument detects the depth it is at and uses that information to split the water column above into three equal depth layers.
  • Eco uses acoustic signals to measure current speed and direction for each of the three depth layers.

How can I use Eco?

  • Eco is rated for a maximum depth of 50 m.
  • Eco has a measurement range of 20 m, but can operate with as little as 30 cm of water above the instrument.
  • Most Eco deployments last around a month or less, but can vary depending on how often you want to take measurements.
  • Eco must be used upward-looking.
Data with background

Outputting data

Eco creates graphs and datasets for you in the Eco WebApp. Easily visualize your data with:

  • Feather plots, polar scatters, histograms and more, showing velocity in three depth layers.
  • Temperature, pressure and tilt measurements.
  • One-click generation of a comprehensive PDF showing all views of your data.

Eco automatically processes your data for you, accounting for factors like tilt, fish interference, and sidelobe interference. Users will not have access to the raw (unfiltered) data.

Deployment options

Deployment 1 eco

Option 1:

Eco buoy system with timed release

This three-part system allows users to deploy Eco in shallow water by simply dropping the buoys over the side of their boat, kayak, paddleboard, or dock. The timed release will send Eco to the surface at the end of the scheduled deployment.

Option 2:

Eco bottom-mount system

Deploying in water shallow enough to wade to? The Eco bottom mount is for you. Designed with portability in mind, this foldable bottom mount will keep your Eco upright and in position throughout your deployment.
