The JFR series, developed by Finetek, is a 26 GHz radar level transmitter that detects liquid, powder and bulk levels with contact. The 5-digit display shows level linear, but can also be programmed with a curve, for silo's or spherical shaped tanks. There are versions for normal liquids and solids, but also specifically for corrosive liquids. In addition to the 26GHz embodiment, there is also the cheaper 10 Ghz execution for a limited number of liquids.
