Abstract

L'INVENTION CONCERNE UN DEBITMETRE DESTINE A MESURER LA VITESSE DE PASSAGE DE GAZ OU DE LIQUIDES ET COMPORTANT UN CORPS SEMI-CONDUCTEUR 1 PLACE DANS LE GAZ OU LE LIQUIDE ET DONT UNE EXTREMITE EST RECHAUFFEE PAR UN FIL DE RESISTANCE ELECTRIQUE 3 DE TELLE FACON QU'UNE DIFFERENCE DE TEMPERATURE ET, PAR LA, UNE DIFFERENCE DE TENSION SOIENT OBTENUES ENTRE LES EXTREMITES DU CORPS SEMI-CONDUCTEUR. LA REDUCTION DE LA DIFFERENCE DE TEMPERATURE VARIANT EN FONCTION DU DEBIT DU FLUIDE ET AINSI LA REDUCTION DE LA DIFFERENCE DE TENSION SONT UTILISEES POUR DETERMINER LA VITESSE DE PASSAGE DU FLUIDE. CECI SE FAIT PAR L'INTERMEDIAIRE D'UN AMPLIFICATEUR 5, A L'ENTREE DUQUEL LE CORPS SEMI-CONDUCTEUR EST CONNECTE ET A LA SORTIE DUQUEL UN SIGNAL REPRESENTANT LA VITESSE D'ECOULEMENT DU FLUIDE APPARAIT.
