Abstract

Mesure d'obstruction ou de la teneur en impuretés d'un métal liquide Un appareil de mesure automatique a un passage refroidisseur avec orifice d'obstruction et débitmètre, et une dérivation, connectée en série avec un passage principal et un autre débitmètre, les points d'obstruction etant obtenus à partir des signaux de sortie des deux débitmètres, ainsi qu'un générateur de signaux de programme, un régleur de rapport de débit et un comparateur. La température de l'orifice est modifiée selon un gradient prédéterminé, au moyen d'un signal de rapport de débit. Applicable notamment aux boucles de sodium liquide de réacteurs nucléaires.
