Abstract
A capacitor fuel probe comprises a plurality of capacitor segments which are superposed on one another along a probe axis. The capacitor segments are distributed into three sets and connected electrically in parallel within each set separately. A capacity measurement which is performed for all the sets allows determining a fuel level while taking into account a possible variation of a dielectric constant of the fuel parallel to the probe axis. Top height values hof the capacitor segments are selected so that h<h·(K−1)/(K−1), for any integer n-value from 2 to N, N being the number of capacitor segments, n varying according a superposition order of the capacitor segments, and Kand Kbeing minimum and maximum values for a fuel dielectric constant which are prescribed for the capacitor fuel probe.
