Abstract: A configuration and a method for capacitive sensing of the rotatory motion of a rotary member are described. The configuration has four electrodes located in one plane, an analysis unit connected to the electrodes and an electrically conducting coupling surface, which is located at the rotary member opposite to the electrodes. The electrodes comprise a central excitation electrode, surrounded by the other electrodes. The coupling surface is opposite to the surface of the excitation electrode in each rotary position and covers a part of the surface formed by the remaining electrodes and passes over the surface formed by the remaining electrodes during a rotation of the rotary member. The remaining electrodes are formed by two sensor electrodes and a joint reference electrode, whereby at least the joint reference electrode is designed different than the sensor electrodes.

Abstract: A configuration and a method for capacitative sensing of the rotatory motion of a rotary member are described, whereby the configuration has four electrodes (1, 2, 3, 4) located in one plane, an attached analysis unit (18) and an electrically conducting coupling surface (5), which is located at the rotary member opposite to the electrodes (1, 2, 3, 4), whereby the electrodes (1, 2, 3, 4) comprise a central excitation electrode (4) surrounded by the remaining electrodes (1, 2, 3), whereby the coupling surface (5) is opposite to the surface of the excitation electrode (4) in every rotary position and covers a part of the surface formed by the remaining electrodes (1, 2, 3), and upon a rotation of the rotary member, passes over various sections of the surfaces formed by the remaining electrodes (1, 2, 3), and whereby the analysis unit (18) has an evaluation circuit (19) that is connected to the excitation electrode (4) for generating excitation pulses (13) having a specified frequency and an evaluation circuit (

Abstract: Method and a device for assessing the consumption of a medium in a supply distribution system using at least one consumption meter, in which the consumption flow values ({dot over (V)}) of the medium consumed are determined based on the consumption values measured over time (Vcum) by the consumption meter. Thereby, a frequency distribution is generated using the consumption flow values ({dot over (V)}), and the consumption is assessed by analyzing the frequency distribution.
