DatawellModel SG (WR-SG) -Waverider Buoys

SHARE

The second generation Waverider SG (WR-SG) is a real-time non-directional wave height measuring buoy. Wave height is measured with a resolution of 1 cm using the well-proven Datawell stabilized platform sensor. The stabilized platform ensures that the buoy accurately tracks the vertical component of the orbital wave motion. In the WR-SG, the platform mounting of the sensor has been reinforced, significantly increasing the robustness of the buoy. The WR-SG is the successor to the Waverider Fl. Whereas the Waverider Fl used analogue techniques to process the wave data, the Waverider SG digitizes the wave signal at an early stage.
