The WaveGuide 5 radar measures the distance to the water surface 10 times per second. Proven is that in all wind and wave conditions the standard deviation for water level is only 1 cm. The radar technology is based on Honeywell Enraf core technology used for tank gauging. Mounted high above the water and without any moving parts there is no need for preventive maintenance or cleaning. (Re-)calibration is never required due to the long-term stable zero reference. The system is compact, robust and easy to install. It is suited to accurately measure wave heights and tides, up to the most extreme conditions. The radar comes in two versions: the Compact version and the ATEX certified version.
