Method and device for determining the filling level

摘要

The method involves immersing an electrode (6) with two ends (14,15), which forms an electrical resistance, in a liquid (4). An immersion length varies according to a level in the liquid. The former end is immersed at a low liquid level (5) in the liquid. A temporary variable current is conducted through the electrode. The current is applied in a pulsative manner. The time limit characteristics of a voltage is evaluated by assigning the liquid level value. An independent claim is also included for a device for determining a level of an electrically conductive liquid in a container.
