Abstract

Integrated system, based on Time Domain Reflectometry analysis, to measure liquid levels, with high repeatability and accuracy, and different phases of complex systems, comprising a TDR unit, a variety of guided-wave probes, a multiplexer to acquire simultaneously data from the different probes, a control software, a protection kit to use the system in critical conditions,whereby the high frequency pulses are guided by the probes, that are introduced directly into the product to be measured.
