Abstract:
1. A measuring arrangement for determining the electrical conductivity of a measured liquid, comprising: a container, in which the measured liquid is accommodated; a gradiometer arrangement, comprising an exciter coil, a first receiving coil and a second receiving coil, wherein said first receiving coil and said second receiving coils are arranged symmetrically relative to said exciter coil, and a measurement circuit embodied to excite said exciter coil for producing an alternating magnetic field passing through said first receiving coil, said second receiving coil and the measured liquid, wherein: said receiving coils are exposed in different measure to a magnetic field induced by said alternating magnetic field in the measured liquid and directed counter to the alternating magnetic field; and said measurement circuit is furthermore embodied to register an electrical signal of said receiving coils and to derive from such the electrical conductivity of the measured liquid.
