  • Fuel tank with integrated level sensors, in particular for aerial vehicles
    Patent number: 11214140
    Abstract: Liquid fuel tank comprising a plurality of liquid level detection capacitive sensors, each arranged along an edge of the fuel tank such that the capacitance of said sensors varies with the volume of fuel present in the fuel tank, wherein an independent liquid level detection capacitive sensor is arranged along each edge of the fuel tank bottom and of the side walls; wherein the tank is electrically conductive and each level sensor comprises an electrically insulating plate arranged thickness-wise between sensor and tank, such that tank and sensors are capacitively uncoupled. Method for obtaining the fuel volume comprising: obtaining the reading of the liquid level detection capacitive sensors arranged on the edges of the tank; calculating the volume, corresponding to the fuel, of the geometric solid defined by the fuel tank and by the upper surface of the fuel as defined by the liquid level readings from the sensors.
