Abstract:
A device for recording the fill level (23) of a liquid inside a container (21) comprising an elongated, flexible tubular electrical contact element (1) arranged in the container and having electrical connection (8, 9) at one end (7) thereof at which connection an electrical signal is measurable,electrically conductive coatings (13, 14) disposed on an inner surface of the contact element (1) and normally spaced from one another, an acquisition element (4, 41) disposed on the outside (5) of the contact element (1), the acquisition element (4, 41) being movable along the contact element (1) in response to changes in the liquid level to bring the electrically conducting coatings into contact with one another, wherein the electrically conducting coatings (13, 14) comprise a resistive coating (13) and a ferromagnetic coating (14).
