Abstract

L'INVENTION CONCERNE LES TECHNIQUES DE MESURE DU DEBIT DE MATERIAUX PULVERULENTS. LE PROCEDE FAISANT L'OBJET DE L'INVENTION EST CARACTERISE EN CE QU'ON SOUMET LE MATERIAU PULVERULENT A L'ACTION D'UN CHAMP ELECTRIQUE DE COURANT CONTINU D'UNE BOBINE 1, POUR CREER SUR SES PARTICULES UNE CHARGE SUPERFICIELLE, ET ON FAIT PASSER LE MATERIAU PULVERULENT AINSI CHARGE A TRAVERS UN CHAMP ELECTROMAGNETIQUE DONT LA VALEUR EST MESUREE EN CONTINU, CE QUI PERMET DE DETERMINER, D'APRES LA MODIFICATION DU CHAMP ELECTROMAGNETIQUE, L'ECART DU DEBIT DU MATERIAU PULVERULENT PAR RAPPORT A LA VALEUR VOULUE. L'INVENTION PEUT ETRE UTILISEE PAR EXEMPLE DANS L'INDUSTRIE DU BATIMENT, LORS DE LA PREPARATION DE MORTIERS.
