Guided wave radar level sensors use microwave technology to provide continuous level measurement of liquids and dry bulk media. The sensors feature a probe that is immersed in the media and sends high-frequency waves down the probe until they meet the surface of the media. Once the high-frequency waves reach the surface of the media, they are transmitted to the sensor.

Guided wave radar level sensors require minimal maintenance, provide accurate readings regardless of changes in pressure or temperature, and are not affected by dust or viscosity.
