The new SM-140 WaveFinderTM is purpose made for accurate wave-measurements from vessels and floating installations. It is based on the SM-140 RangeFinder and its market- leading range and accuracy specifications, complemented with an integral high-precision motion reference unit. The 5° narrow-beam antenna gives a small footprint on the sea surface, enabling the sensor to measure shorter wave-periods from a longer distance than sensors with 10° antennas. Wave variables are calculated both from timeseries data and from the wave spectrum. The sensor is available in an Ex approved version.

The SM-140 WaveFinder is a stand-alone sensor with embedded processing and storage, enabling data to be easily and securely accessible both locally and remotely by utilizing modern IoT technologies.

It is compact and easy to install. Only a network connection and power are required. The narrow beam antenna enables a more flexible installation alongside the hull.

The sensor has proved its ruggedness and reliability through many years of service in extreme weather conditions, all over the world.
