The Nortek Acoustic Wave and Current Profiler sensor is a current profiler and directional wave system in one unit. The NORTEK AWAC is well suited for both autonomous data collection and as part of a real-time data telemetry system. Subsurface deployment means the instrument is always protected from harsh weather, vandalism, and ship traffic. The small, yet rugged instrument is suitable for multi year operation in tough environments. Plastic and titanium parts avoid corrosion. The NORTEK AWAC Current Profiler is available in three transmit frequencies for operational ranges spanning 2m to 100m.
