Simultaneous measurement of dielectric properties and levels of liquids using a TDR method

摘要: Several monitoring methods, in the recent years, involved microwave/radio frequency (RF) reflectometry techniques, particularly remote sensing, environmental and industrial application fields. The main advantages using are due to its relevant performance characteristics, terms of high flexibility, sensitivity large conditions. Furthermore, time domain (TDR) presents some attractive advantages, related possible determination spatial location nature various objects, real-time with a non-destructive approach. This makes TDR technique an appealing candidate for variety applications. Although instruments commonly used today, above mentioned purposes, state art is rather lacking liquid In this paper we demonstrate that suitable combination detecting functionalities, localization, dielectric properties estimation coaxial probe leads enhanced quantitative qualitative method. Really, one shot, analysis data allows measurement levels, multiple interfaces layered media, as well evaluation properties, such permittivity or electrical conductivity. Moreover, applications real cases proposed, referred petrol–chemical mixtures water-based liquids, thus validating approach on wide range materials.
