Abstract:
1. A liquid fuel tank for measuring fuel volume, connected to measuring equipment to measure the fuel volume based on refraction of light on different mediums by means of transmission/reception of light via optic fibres, the liquid fuel tank comprising: inner lateral faces of the tank, wherein at least one face of the inner lateral faces of the tank has at least one sheet whose rear face includes an array of optic fibre cables of different lengths, the optic fibre cables being located between the at least one face of the inner lateral faces of the tank and the at least one sheet in such a way to provide complete protection for the optic fibre cables, wherein lengths of the optic fibre cables are sized between a size corresponding to a minimum level of fuel up to a size corresponding to a maximum level of fuel, wherein one end of the optic fibre cables, selected between an upper and a lower end, are arranged so that they make contact with the fuel when the fuel reaches their level, the fibres of the optic fibre cables being cut at the same level as the sheet for measuring a level of fuel at any moment, and wherein an opposite end of the optic fiber cables are connected to the measuring equipment.
