ABSTRACT:
A device for the electric measurement of the level of a liquid within a container has a protective tube (1) within which a conductive foil (2) is helically arranged. The conductive foil (2) is wound with such a pitch that sufficient space remains between its longitudinal edges (3, 3') to provide a helically extending flexible protective-tube region (16, 16') within the protective tube (1). This protective-tube region has inwardly and outwardly directed U-shaped tube sections (17, 18, 19). As a result of this development the protective tube (1) bends exclusively in those regions which are located between the longitudinal edges (3) of the conductive foil (2).
