Nortek 1 MHz acoustic wave and current profiler
|Within Vocab||SeaVoX Device Catalogue|
|Alternative Labels||Nortek 1 MHz AWAC|
|Definition||An instrument that simultaneously measures current profiles and wave height and direction designed for coastal monitoring. It transmits at 1 MHz giving a range of 30 m (waves measurable with deployment depth up to 35 m) and a cell size of 0.25-4 m (maximum 128 cells) and has four beams, one vertical and the other three 120 degrees apart slanted at 25 degrees. Current speeds up to 10 m/s may be measured at an accuracy of 1% of measured value ±0.5cm/s. Temperature (embedded thermistor with 0.1C accuracy and 0.01C resolution), compass (magnetometer with 2 degrees accuracy and 0.1 degree resolution providing tilt <15 degrees), tilt (liquid level) and pressure (piezo resistive with accuracy of 0.5% (optional 0.1%) full scale - usually 100m - and resolution of 0.005% full scale) sensors are provided as standard.|
