In this paper, a reconfigurable system based on sound resonance for measuring the fill-level of a tank from the exterior is presented. A relation between sound resonance frequencies and the content of the tank has been found, especially as the tank gets closer to being full. A prototype has been created using reconfigurable technologies combined with wireless communications in order to control the system from an ad hoc application. With this prototype, the fill-level of different tanks has been measured with good resolution, especially when the tank is over half of its capacity.}, publisher = {MDPI}, keywords = {Tank-filling sensor}, keywords = {Fill-level sensor}, keywords = {Reconfigurable instrumentation}, keywords = {Sound resonance}, title = {Non-Intrusive Tank-Filling Sensor Based on Sound Resonance}, author = {García, Adrián and Toral López, Víctor and Márquez, Álvaro and García, Antonio and Castillo, Encarnación and Parrilla Roure, Luis and Morales Santos, Diego Pedro}, }
