The device () comprises a body () in which are formed a first and second chamber () separated sealingly from each other by a resilient diaphragm (). The first chamber () has an inlet opening () intended to be put in pneumatic communication with the region of a container which is above the liquid; the second chamber () communicates with the atmosphere. A winding () is mounted in a fixed position in the body (), on the side opposite the first chamber () with respect to the diaphragm (). A core () is coupled to the diaphragm () and is movable with respect to the winding () such that in operation the inductance of the winding () varies as a function of the position of the core. The device also comprises a first spring () tending to move the core () towards the diaphragm (), and a second spring () tending to oppose the action of the first spring (). The second spring () is positioned in the second chamber ().
