The invention relates to a device for measuring the filling level of a filling medium (1) in a medium (2) according to the plumb line principle, comprising a rope roller (3), a guide rope (4) and a test body (5) arranged on the guide rope (4). The test body (5) can be brought into contact with the surface of the filling medium (1). The guide rope (4) runs over the rope roller (3) in such a way that the roller can be rotated by moving the guide rope in an upward and downward movement. A means (6) for measuring the rotation of the rope roller (3) and an electronic evaluation system (7) are also provided. The latter is adapted for use with a liquid as a medium that is to be measured, whereby the filling level thereof is to be measured in a continuous manner. The test body (5) is thus embodied as a float and floats on the surface of the liquid (1), and the rope roller (3) is associated with a tensing means (8) enabling the guide rope (4) to be continuously tensed between the test body (5) and rope roller (3), whereby the test body (5) cannot be raised without liquid (1). . |
