| 摘要 |
An fuel level detector includes a substrate fixedly mounted inside an fuel tank, a narrow elongated first electrode arranged on the substrate and kept in contact with the fuel oil in the fuel tank, a second electrode formed of a plurality of electrode elements arranged on the substrate at different elevations in a parallel manner relative to the first electrode, and a sensing circuit formed of a plurality of capacitive sensors that are respectively electrically connected with the electrode elements of the second electrode for detecting the level of fuel oil in the fuel tank subject to a rise in capacitance value between the first electrode and one electrode element of the second electrode.
