Device for determining a composition of a fuel mixture by means of a coaxial waveguide through which the fuel mixture is flowing

摘要

A device for determining a composition of a fuel mixture is provided, in particular for determining an ethanol component and/or a water component in the fuel mixture. The device includes at least one housing having at least one electrically conductive housing element through which the fuel mixture is able to flow. At least one internal conductor, which is at least partially enclosed by the housing element, is introduced into the housing element. In addition, the device has at least one connection device for the coupling of microwave signals.

1. A device for determining a composition of a fuel mixture, comprising:
at least one housing having at least one electrically conductive housing element through which the fuel mixture is able to flow, wherein at least one internal conductor is introduced into the housing element, the at least one internal conductor being at least partially surrounded by the housing element; and at least one connection device for coupling microwave signals, wherein the housing element has at least one cup which at least partially surrounds the internal conductor, wherein the cup has a plurality of bores, the bores having a diameter which is smaller than the smallest wavelength of the incoupled microwaves.
