DEVICE FOR DETERMINING THE COMPOSITION OF A FUEL MIXTURE BY MEANS OF A COAXIAL WAVEGUIDE THROUGH WHICH THE FUEL MIXTURE FLOWS

摘要

A device (110) is proposed for determining the composition of a fuel mixture, in particular for determining a proportion of ethanol and/or a proportion of water in the fuel mixture. The device (110) comprises at least one housing (116) with at least one electrically conductive housing element (128) through which the fuel mixture can flow. At least one internal conductor (140) inserted into the housing element (128) and is at least partially surrounded by the housing element (128). The device (110) also has at least one connecting device (146) for coupling microwave signals.
