Wave Radars

AWAC 2 - 600 kHz

Real-time current profiles and directional waves for intermediate water

The AWAC 600 kHz ADCP has become the standard reference technology in submerged wave-measurement applications. Thousands of these ADCPs have been deployed to capture the full wave spectrum in combination with current profiles. With a 60 m maximum range for wave measurements and 2 Hz sampling of the surface elevation, the AWAC 600 kHz is the optimal tool for medium water-depth current and wave measurements. The AWAC 2 design offers future-proof electronics, improved performance and easier deployment and maintenance.
