ABSTRACT:
A device for the electric measurement of the level of a liquid in a container has a protective tube (1) within which a conductive foil (10) is arranged twisted. The protective tube is a corrugated tube with corrugations (2, 3). These corrugations (2, 3) have interruptions (4, 5, 7, 8). The interruptions lie along two helical lines (6, 8). The conductive foil (10) is pushed with its longitudinal edges (11, 12) into these interruptions (4, 5) which lie on two helical lines (6, 9). In order to permit of easy bending of the entire device, the conductive foil (10) has incisions (13, 14) which extend from both longitudinal edges (11, 12) up to the center of the conductive foil (10).
