Abstract

DISPOSITIF DESTINE A DETERMINER LE DEBIT ETOU LA VISCOSITE D'UN COURANT FLUIDE CIRCULANT DANS UNE CONDUITE. SELON L'INVENTION, CE DISPOSITIF EST CARACTERISE EN CE QU'IL COMPORTE D'UNE PART UN TUBE RIGIDE DESTINE A ETRE INSERE DANS LADITE CONDUITE ET COMPORTANT UN RETRECISSEMENT ET D'AUTRE PART UN CAPTEUR SEMI-CONDUCTEUR SENSIBLE A LA PRESSION, MONTE DE FACON ETANCHE SUR LADITE CONDUITE AU NIVEAU DUDIT RETRECISSEMENT DE FACON QUE SA SURFACE SENSIBLE SE TROUVE A L'INTERIEUR DE CELUI-CI.
