Abstract
LES INTERRUPTEURS A FLOTTEURS INSTALLES DIRECTEMENT SUR LE RESERVOIR DE LIQUIDE DE PRESSION OU SUR UN TUBE DE NIVEAU COMMUNICANT AVEC LE RESERVOIR SONT REMPLACES PAR DES BARRIERES ULTRASONORES, COMPRENANT CHACUNE UN EMETTEUR 7 ET UN RECEPTEUR 8 D'IMPULSIONS ULTRASONORES ET UN APPAREIL DE COMMUTATION 9 POUR LA COMMANDE DE POMPES, VANNES, OU DISPOSITIFS DE SECURITE. LES EMETTEURS, 7, LES RECEPTEURS 8 ET LES APPAREILS DE COMMUTATION 9 SONT MONTES SUR LA PAROI EXTERIEURE 6 DU RESERVOIR 1 ET NE VIENNENT PAS EN CONTACT AVEC LE LIQUIDE DE PRESSION SE TROUVANT A L'INTERIEUR. CHAQUE BARRIERE ULTRASONORE CORRESPOND A UN ETAGE DE PRESSION, LEQUEL PEUT ETRE CHANGE FACILEMENT PAR LE REGLAGE EN HAUTEUR DE L'EMETTEUR 7 ET DU RECEPTEUR 8 CORRESPONDANTS. L'INVENTION EST APPLICABLE NOTAMMENT A L'ALIMENTATION EN ENERGIE MOTRICE DE GROSSES PRESSES A FORGER.
