Abstract
DISPOSITIF PERMETTANT DE MESURER LE DEPLACEMENT RELATIF D'UN FLUIDE PAR RAPPORT A UNE PAROI SANS AVOIR A PERCER CETTE DERNIERE POUR RECUEILLIR L'INFORMATION. IL COMPREND DEUX ELEMENTS BIEN DISTINCTS: UN EMETTEUR 8 ET UN CAPTEUR 1 PLACES DE PART ET D'AUTRE DE LA PAROI 5. L'EMETTEUR EST CONSTITUE D'UNE TURBINE CONTENANT UN OU PLUSIEURS AIMANTS ET ANIMEE EN ROTATION PAR LE FLUIDE 6. LE CAPTEUR 1 PLACE SUR L'AUTRE FACE DE LA PAROI 5 EST CONSTITUE D'UN RECEPTEUR MAGNETIQUE 3 COUPLE LOCALEMENT A UN AMPLIFICATEUR A GRAND GAIN 2. L'INVENTION PEUT ETRE UTILISEE COMME LOCH SUR UN NAVIRE SANS AVOIR A PERCER LA COQUE, MAIS EGALEMENT POUR MESURER LA VITESSE D'ECOULEMENT D'UN FLUIDE DANS UNE CANALISATION QUELCONQUE SANS AVOIR A PERCER CETTE DERNIERE.
