Since 1996, Radac has been developing, manufacturing and marketing the WaveGuide: a very accurate radar level gauge to measure environmental data in offshore, maritime and marine environments. Leading companies all over the world rely on our systems.


  • Maintenance-free
  • Easy installation
  • Suitable for all weather conditions
  • Low power consumption
  • Explosion-proof certified (as an option)
  • Excellent price/performance ratio

The WaveGuide radar measures the distance to the water surface several times per second. Proven is that in all wind and wave conditions the standard deviation for water level is only 1 cm. The device consists of a radar (based on Honeywell Enraf core technology) and a processing unit. 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 standard stainless steel version and the ATEX certified version.

The WaveGuide Processing Unit facilitates commissioning, remote servicing, data collection, data processing, presentation and logging. The processing unit communicates with the radar via a serial link (RS232/RS485). The system is based on a low power processor, does not have any moving parts and can synchronise to UTC-time.

Data can be distributed through its two extra serial ports as well as via network packets. The user can configure the data sets (raw data, spectra, parameters) using the subscription interface. Radio, gsm, gprs and satellite modems are supported.

Raw data, spectra and parameters can be requested and are presented within the web-browser. A selection of the most recent data is presented on the lcd display of the WaveGuide Processing Unit.

All of our systems are suitable for marine use. However depending upon the type of functionality required by the user, all four installations have unique qualities specific to the system itself:
