Abstract

Le dispositif de mesure comprend : - au moins une fibre optique (15) ; - une source de lumière (17) ; - un analyseur (19), prévu pour analyser un rayonnement lumineux rétrodiffusé par la fibre optique (15) et pour en déduire le niveau de liquide par rapport au fond (9). Le dispositif de mesure (1) comprend un flotteur (21) flottant à la surface libre (13) du liquide, le flotteur (21) comportant un passage (23) dans lequel la ou chaque fibre optique (15) est reçue de manière coulissante, un tronçon (25) de la fibre optique (15) engagé dans le passage étant pincé ou dévié.
