Abstract (en)

[origin: WO2014001714A1] The invention relates to a device for detecting the level of a liquid (1) contained in a container (2) comprising: - a means for detecting the level of the liquid (3); - a temperature sensor (4) comprising an optical fibre (41) comprising a plurality of Bragg gratings (411) distributed along the length of the optical fibre (41), said sensor (4) comprising means for determining the temperature of the liquid measured by the optical fibre (41) in a plurality of areas (412), each area (412) being located close to each of said Bragg gratings (411); and - an analysis means for determining the level of the liquid contained in the container from the temperature measured by the optical fibre in a plurality of areas (412).
