SM-094 Range Finder

The Range Finder is an accurate and reliable radar sensor for measurement of water level, tide, waves and air gap. The sensor signal processing is performed by a microcontroller and provides the measured range as well as an averaged range with 1 mm resolution. Averaging time constant may be selected by user. The SM-094 Range Finder microwave sensor is unaffected by temperature and will penetrate and operate undisturbed in fog, rain and water spray. The sensor is available in different range versions from 1 to 85 meters, with different antenna beam width.

The main applications are sea level and non-directional wave monitoring at ports and coastlines, water level monitoring at rivers, dams, canals and lakes, and air gaps monitoring from bridges.
