Contactless fill level measurement of liquids

摘要

The device (100) has measuring electrodes (103-112) arranged in different horizontal planes, where the measuring electrodes define a measurement surface with a vertical extent. A reference electrode (113) defines a reference surface with the vertical extent. The measuring electrodes form capacitors together with the reference electrode, so that an electric field is formed, where the vertical extent of the reference surface corresponds to the vertical extent of the measurement surface. An independent claim is also included for a method for non-invasive capacitive measuring a liquid level of a filling medium in a container.
