Abstract
To increase the measuring precision of an electric measuring assembly () for capacitively measuring a liquid, an inner electrode () and an outer electrode () arranged concentrically to the inner electrode is provided, in which a shielding electrode () is arranged between the outer electrode () and the inner electrode (). The potential of the shielding electrode () can be actively adjusted to the potential of the inner electrode () by a corresponding electric connection such that electric fields which are caused by dielectric displacements in parasitic capacitances are effectively shielded from the inner electrode () and thus from the capacitance to be measured. For this purpose, a two-part design of the inner electrode () is provided with sections () and () which can be moved axially relative to each other.
