Abstract

As a continuation of a previous theoretical study, we propose here preliminary experimental results about the application of the TDR technique to a coaxial reflectometric sensor used as level monitoring device. This kind of sensor may offer some interesting features for the design of nuclear facilities control systems and oil and gas plants. In order to experimentally verify the theoretical results, the sensor is used as a level control for a hydraulic loop system, firstly in a static condition, then its usage planned under a dynamic variation of the liquid level with different transient times. As a matter of fact this hydraulic loop system, yet simple, can offer short/medium-term transient level dynamics requiring fast sensor response, on-line measurement and some non-linearity features that are crucial for its control. In this paper, a second-order nonlinear ODE governing the system dynamics is theoretically analyzed, and the hydraulic loop prepared for its experimental observation through the use of a coaxial reflectometric sensor and a novel kind of pump with very low-pulsatility flux suitable for this study, managed by an advanced level detection algorithm.
