The Datawell Wave unit is an OEM version of the wellknown Directional Waverider MkIII for measuring wavemotions in three directions. The unit gives out the real time heave, north and west displacements as well as common wave parameters like Hs and Tz and spectral data. The Wave unit is built around Datawell’s accurate and well-proven stabilized platform sensor, enabling wave height measurements by a single accelerometer. For the wave direction, direct pitch and roll measurements are performed needing no integration. In combination with horizontal accelerometers and a compass this forms the complete sensor unit, the heart of the Wave unit.
The Wave unit is essentially a DWR-MKIII Waverider buoy in an OEM package. It is meant to be integrated as a complete sensor package in oceanographic and meteorological buoys. Interface The Wave unit is equipped with an RS-232 interface and a power converter. Both the power converter and the RS-232 interface are galvanically isolated for easy integration and overall robustness. The power converter is suitable to accept a wide input voltage range from 10V up to 30V DC. The data format of the Wave unit is compatible with the format as sent out by a DWR-MkIII and the information is received, interpreted and transmitted by Geonica's METEODATA/HYDRODATA datalogger unit. Installation The Wave unit may not be exposed to sea water and must be installed in a water tight compartment. Also keep away any magnetic parts, since they will interfere with the magnetic compass measurements and affect the measured wave direction.
