Abstract

Ce dispositif pour indiquer les variations du poids spécifique d'un liquide comprend un premier et un second flotteurs 10, Il, adaptés pour flotter sur la surface du liquide, les flotteurs ayant des formes et/ou des densités différentes de sorte que la profondeur d'immersion des flotteurs dans le liquide varie en fonction du poids spécifique du liquide, et des moyens pour produire un signal électrique fonction de la profondeur d'immersion des flotteurs l'un par rapport à l'autre dans le combustible contenu dans le réservoir de liquide.
