In the present paper an assessment of time domain reflectometry (TDR) measurements for simultaneous detection of dielectric properties and levels of liquids is proposed. In a previous paper  the Authors developed a detection method demonstrating that TDR can be successfully used for an enhanced real-time monitoring of liquid inside tanks: in one shot, the determination of levels, dielectric properties and multiple interfaces in layered media are possible, thus opening challenging perspectives for several monitoring applications, especially for industrial and environmental control purposes. It is worth to note that stringent requirements in liquid monitoring applications, frequently limit the use of traditional liquid sensing technologies, such as ultrasonic or capacitive sensors. The above mentioned method can be identified as a substantial improvement with respect to existing approaches . Based on these results, we will present in this work a comprehensive study in order to evaluate the performance level of such technique in terms of measurement accuracy. The main purpose of the present work is to analyse the qualitative and quantitative TDR method proposed by the Authors in  from a metrological point of view, leading to an assessment on the measurement uncertainty and to a validation of the method itself.
