Second generation non-directional wave height measuring buoy.

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 analog techniques to process the wave data, the Waverider SG digitizes the wave signal at an early stage. Combined with the same processing hardware as the directional DWR-MkIII and DWR-G buoys, many features and options are now standard which were not possible on the previous model.
