ABSTRACT:
The present invention relates to an improved liquid-level indicator. The liquid-level indicator comprises an upstanding tube and a float arranged for vertical movement therein. This float is provided with a permanent magnet which is polarized in a horizontal plane and influences magnetically an array of display elements. These display elements are located outside of the tube. The display elements are rotatably supported and arranged in succession one above the other. Between the display elements and the tube there extends a magnetic strip arranged such that the permanent magnet of the float is oriented towards the display elements. This magnetic strip also pre-tensions the display elements. It is located outside of the tube and at a distance from the float.
