Page 201: Technical Reference
Technical reference Principles of operation SITRANS LR500 series is a 2-wire, 80 GHz FMCW (Frequency Modulated Continuous Wave) radar level transmitter for continuous monitoring of liquids, solids and slurries in vessels to a range of 100 m (329 ft) . Radar level measurement uses the time of flight principle to determine distance to a material surface.
