Abstract

L'invention concerne un dispositif de lecture à distance du niveau d'un liquide contenu dans une capacité telle qu'une cuve de pulvérisateur agricole destiné au traitement en continu de végétaux. Ce dispositif est caractérisé en ce qu'il est constitué d'au moins un organe sensible à la pression du fluide relié par des moyens de transmission à des agents d'affichage permettant la lecture à distance du niveau de fluide contenu dans la cuve.
