Abstract
The invention relates to a method and system for the capacitive identification of a container which is filled with an electrically conductive liquid. In this case, a container or the content thereof is identified by capacitive coupling by a surface sensor. The invention further relates to a use of the method or system, for example for distinguishing different electrically conductive liquids.

19. Use for capacitively distinguishing electrically conductive liquids in a container,
characterized in that the liquids have variable properties which influence the electrical conductivity of the liquid and thus the capacitance of the overall system comprising liquid and container and can thus be distinguished capacitively by a surface sensor.
