An evaluation of performance limits in continuous TDR monitoring of permittivity and levels of liquid materials

摘要: Abstract Time domain reflectometry (TDR) is commonly used for several monitoring applications, particularly in hydrology and soil science water content evaluation. Furthermore, significant advantages of TDR methodology, such as its relevant performance characteristics terms high flexibility sensitivity, well a non-destructive detection approach, render this technique an appealing candidate variety environmental industrial applications. In previous paper [A. Cataldo, L. Tarricone, F. Attivissimo, A. Trotta, Simultaneous measurement dielectric properties levels liquids using method, Measurement, doi:10.1016/j.measurement.2006.11.006 ] the authors demonstrated that can be successfully simultaneous real-time qualitative quantitative liquids. paper, rigorous metrological characterization proposed method formulated, uncertainty contributions are identified. The obtained results, confirm system definitely adequate simultaneously measuring constants liquids, with associated relative uncertainties 2% 3%, respectively, all considered liquid samples. This way, challenging perspectives applications open, especially processing
