Abstract:
1. An apparatus for discriminating between two fluids and allowing a first fluid to flow and preventing a second fluid from flowing in a filler tube, the first fluid comprising a first density and the second fluid comprising a second density, the apparatus comprising: the discriminating apparatus disposed in an inlet of the filler tube; an actuating tube for accepting a portion of the first or second fluid; a magnetic structure comprising a material that floats in one of the two fluids, comprising the first density, and sinks in a second of the two fluids, comprising the second density, disposed in the actuating tube; and a stopper, the stopper comprising a filler tube blocking apparatus, that prevents the second fluid from flowing into the filler tube, said stopper being activated by the magnetic structure, whereby the magnetic structure floats or sinks, depending on a density of the fluid being introduced and magnetically attracts a stopper release apparatus when the magnetic structure reaches a predetermined distance to the stopper release apparatus.
