Abstract

DISPOSITIF UNIVERSEL DE MESURE DE NIVEAU, DEBIT ET PRESSION PARTICULIEREMENT INDIQUES POUR FLUIDES DANGEREUX. LA GRANDEUR PHYSIQUE SERVANT A LA MESURE EST UNE FORCE ENGENDREE PAR UNE PRESSION, UNE POUSSEE HYDRODYNAMIQUE OU UNE POUSSEE HYDROSTATIQUE. LE DISPOSITIF COMPREND UNE BALANCE ELECTRODYNAMIQUE CONSTITUEE PAR UN COUTEAU 10, UN BRAS DE COMMANDE 20 ET UN ELECTRO-AIMANT 42. LA FORCE A MESURER S'APPLIQUE A UNE EXTREMITE DU BRAS DE COMMANDE NORMALEMENT A CE DERNIER. L'ELECTRO-AIMANT CONSTITUE, AVEC UNE ANCRE DISPOSEE A L'AUTRE EXTREMITE DU BRAS, UN CONDENSATEUR VARIABLE DONT LA CAPACITE SERT A MESURER LADITE FORCE. LEDIT COUTEAU EST CONSTITUE PAR UNE CLOISON. APPLICATION, PAR EXEMPLE, A DES MESURES OPEREES SUR DES METALLOIDES A L'ETAT LIQUIDE.
