<p>A capacitive fuel level gauge for detecting the fuel level inside a fuel tank by using a double coaxial structure, wherein the capacitive fuel level gauge comprises a double coaxial structure configured from a central electrode, an outermost ground electrode, and a switching electrode positioned between the central electrode and the ground electrode, and the fuel level and fuel permittivity (ε) are measured through the selective measurement of the capacitance (C1) between the central electrode and the switching electrode and the capacitance (C2) between the ground electrode and the switching electrode.</p> |
