MicroTREK - (Guided Microwave) : LEVEL TRANSMITTERS :


The MicroTREK guided microwave level transmitter is designed for continuous level measuring of conductive or non-conductive liquids, pulps and solids. MicroTREK 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. The TDR technology is unaffected by the properties of the medium as well as that of the space above it. Measurement is also unaffected by the change in the physical properties of the materials such as temperature, pressure, dielectric constant.
