500 m

Courantomètre ponctuel polyvalent avec en option mesure de la houle PUV

Aperçu

The Aquadopp 300 m is a compact, accurate and affordable single-point current meter for applications where a current profile is not needed. Designed for use in a number of deployment scenarios from mooring lines to bottom-mounted structures, it comes with PUV-based directional wave measurement capability as standard, making it the best value in the industry.

Raw magnetometer data can be stored for post calibration of compass when used without the inductive modem option.

  • Currents
  • Waves

Points forts

  • Single-point current meter
  • Perfect for mooring lines
  • PUV-based directional wave measurements

Utilisation

  • Attached to mooring lines
  • In conjunction with riser monitoring systems
  • Measurements of unaffected currents from physical structures
  • Shallow-water wave and current measurements
  • Alternative to mechanical current meters with errors due to fouling
  • Near-surface current measurements from surface buoys
  • Studies of tidal currents
  • Suitable for wave buoys

Setup

Nortek deployment software allows users to customize their 300m 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 with a designated mooring-specific head design available, 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.
