600 kHz

Profil de courant et houle directionnelle en profondeurs intermédaires


L'AWAC 600 kHz est l'instrument de référence pour les mesures de houle à partir du fond. Des milliers d'AWAC ont déjà été déployés à travers le monde pour mesurer la houle directionnelle ainsi que les profils de courant. Avec une portée de 60 m et avec un échantillonnage jusqu'à 2 Hz de la surface, l'AWAC 600 kHz est l'outil de prédilection pour les mesures de courant et de houle en profondeur intermédiaire.

  • Currents
  • Waves

Points forts

  • Profil de courant et houle jusqu'à 50 m
  • Tracking acoustique de la surface (AST) avec un faisceau vertical
  • Utilisable sur structures fixes ou bouées de subsurface


  • Mesure temps réel du courant et de la houle
  • Design data for planning of new coastal structures
  • Aménagement de structures côtières
  • Étude érosion côtière
  • Campagne de mesures où le spectre directionnel total de houle est souhaité
  • Étude d'agitation en milieu portuaire
  • Étude des courants de marée


Designed for straightforward and reliable current and wave measurements in up to 50m of water, the AWAC 600kHz is configured using Nortek deployment software before installation. The AWAC is often considered the industry standard in wave measurements.


AWACs are often bottom-mounted and/or implemented as part of real-time wave monitoring systems. Leading industry partners offer bespoke frames and buoys for the AWAC, Multiple communication protocols make simultaneous power and data transmission easy.


Optional onboard wave processing allows real-time streaming of wave parameters to users onshore. Nortek’s SUV processing method (exclusive to AWACs and Signatures) enables quality wave measurements from a moving subsurface buoy. Nortek postprocessing software and/or display software is available for review or visualization of data, after deployment or in real time.
