Fuel tank with integrated level sensors, in particular for aerial vehicles

A method for obtaining the fuel volume of a fuel tank of the type having a fuel tank bottom and side walls, the fuel tank comprising a plurality of liquid level detection capacitive sensors positioned so that the capacitance of said sensors varies with the volume of fuel present in the fuel tank, wherein the liquid level detection capacitive sensors are arranged along each edge of the fuel tank bottom and of the side walls, wherein the fuel tank is electrically conductive and each liquid level detection capacitive sensor comprises an electrically insulating plate each arranged thickness-wise between each capacitive sensor and the fuel tank, the thickness of said plate being such that the fuel tank and the capacitive sensors are capacitively uncoupled for liquid level detection, the method comprising the steps of:

• obtaining the reading of liquid level detection capacitive sensors arranged on edges of the fuel tank;
• and
• computing 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 capacitive sensors on the edges of the tank.
