Abstract (en)

[origin: WO9946567A1] Device to indicate the level of a liquid (2) contained in a thin-walled tank (1) inside which a permanent magnet (4) is made to float on the liquid (2) and outside which a strip of ferromagnetic material (8) is attached vertically, which strip is sensitive to the flux which the permanent magnet (4) emits and which will act as a guide. On the guiding strip and in correspondence with the permanent magnet (4) a light spheroid element made of ferromagnetic material (8) is positioned which will be attracted and suspended on the outer wall, so that the displacement of the permanent magnet (4) inside the tank, due to variations in the quantity of liquid (2), will entail, on the outside of the tank, the displacement of the spheroid element (8) and this will indicate at every moment the position of the permanent magnet (4) which will correspond to the level of liquid (2) inside the tank (1).
