The GF Signet 2291 guided wave radar level transmitter is designed for continuous level measuring of conductive or non-conductive liquids, pulps and solids. The 2291 level gauge operates based on the well-known TDR (Time Domain Reflectometry) principle. Micropulses are sent along a probe guide at the speed of light. As soon as the impulse reaches the surface of the medium, it is reflected back to the electronic module. Level distance is directly proportional to the flight time of the impulse.
The series 2291 guided wave radar level transmitter is ideal for use in the following applications: Inventory tanks, day tanks, process vessels for mixing and batching, bypass applications (require calibration), stilling-wells, powders, slightly conductive foams and low dielectric constant liquids.
