摘要：

Flow sensors are widely used in several application contexts. In this paper a novel sensing approach to implement a low cost flow sensor is presented. The proposed methodology is based on the use of a ferrofluid volume to convert the flow rate into a measurable mass displacement. The ferrofluid movement is detected by an external inductive readout strategy. In this paper, the sensing strategy is illustrated along with a laboratory prototype and experimental results assessing the suitability of the methodology implemented.
