A third generation, non-invasive, highly stable system for the measurement of Waves and Sea Level in the offshore, renewable energy and coastal monitoring environments.


  • Stable in the most adverse weather conditions
  • Suitable for permanent or temporary installation
  • BASEEFA03ATEX or UL EEx - certified
  • No re-calibration required
  • Ideal upgrade for existing systems

Typical applications:

  • Safety status monitoring
  • Sea state assessment for operations
  • Structural monitoring
  • Input to Met-Ocean systems
  • Weather forecasting
  • Water level observations
  • Air-gap studies
  • Wind farm monitoring

Microwave radar is a perfect medium for the extreme demands of the harsh offshore environment. The downward looking non-contact sensor uses a microwave radar technique to measure distance to the sea surface.

Sampled at high frequency, the radar pulses provide an exceptionally stable and accurate measurement of sea surface profile. The microwave signals are very low in power and present no safety hazard. Information is continuously collected and processed to provide precision distance measurement outputs to a data bus.

Output values can be displayed and stored to industry standards on a remote PC or may be interfaced to multi-parameter environmental monitoring systems. WaveRadar Rex provides digital (RS232) and analogue (current loop) outputs as standard with either AC (M) or DC (D) power options.
