Reproducibility analysis of a TDR-based monitoring system for intravenous drip infusions: Validation of a novel method for flow-rate measurement in IV infusion

In previous works, the authors have explored the use of a microwave reflectometry-based system for the automatic control and real-time monitoring of the flow and of the liquid level in intravenous medical infusions. In this paper, the repeatability of the measurements obtained with the proposed method is evaluated, by employing an ad-hoc experimental procedure. Preliminary results demonstrate that the method shows a good repeatability; nevertheless, there are still some issues that should be solved.
