The Nortek Acoustic Waves and Currents (AWAC) sensor is a current profiler and directional wave system in one unit. is well suited for both autonomous data collection and as part of a real-time data telemetry system. The small, yet rugged instrument is suitable for multi-year operation in tough underwater environments. Plastic and titanium parts avoid corrosion. The AWAC is available in three transmit frequencies for operational ranges spanning 2m to 100m

Optional Sensors

No optional sensors provided. Please add sensors.

Notes, Considerations & Recommendations

Requires post processing software. AWAC AST can process the data. The WAVES software provides more processing capability but requires the purchase of a license. CT sensor available as optional component.
