Abstract
DISPOSITIF DE MESURE SANS CONTACT DU NIVEAU DE LA SURFACE DE SEPARATION D'UN LIQUIDE ET D'UN MILIEU DIFFERENT. UNE ELECTRODE, SITUEE A UNE CERTAINE DISTANCE DE LA SURFACE DE SEPARATION DU LIQUIDE, CONSTITUE AVEC CELLE-CI UN CONDENSATEUR ELECTRIQUE. UN CAPACIMETRE ELECTRONIQUE RELIE A CE CONDENSATEUR DELIVRE UN SIGNAL QUI PEUT ETRE UTILISE SOIT DIRECTEMENT POUR FAIRE UNE MESURE DU NIVEAU DE LA SURFACE DE SEPARATION SOIT A TRAVERS UN SERVOMECANISME POUR ASSERVIR L'ELECTRODE A SUIVRE CE NIVEAU. AU MOYEN DES DISPOSITIONS DECRITES DANS L'INVENTION, LE DISPOSITIF S'APPLIQUE A LA MESURE DE LA POSITION DE LA SURFACE DE SEPARATION DE DEUXLIQUIDES DE NATURE DIFFERENTE. L'INVENTION PEUT ETRE UTILISEE, ENTRE AUTRES APPLICATIONS, POUR DETECTER, MESURER, CONTROLER DES NIVEAUX DE METAUX EN FUSION, DES POLLUTIONS SUPERFICIELLES DE NAPPES PAR DES HYDROCARBURES.
