Title (EN) CHEMICALLY INERT FLOW CONTROLLER WITH NON-CONTAMINATING BODY
(FR) REGULATEUR DE DEBIT CHIMIQUEMENT INERTE POURVU D'UN CORPS NON CONTAMINANT
Abstract:
(EN) A flow controller including a unitary controller body with a chemically inert fluid conduit having an insertable constriction or orifice disposed within the conduit having a reduced cross-sectional area to thereby restrict the flow of fluid within the conduit allowing for reliable flow measurement. An integrated circuit or controller may becoupled to the control valve and also coupled to the pressure sensors by a lead structure including signal conductors surrounded by a Faraday cage, and a chemically inert housing coupled to the unitary controller body enclosing the control valve and the pressure sensors.
(FR) Régulateur de débit possédant un corps monobloc pourvu d'un conduit à fluide chimiquement inerte. Un élément d'étranglement ou à orifice, pouvant être introduit, est placé à l'intérieur du conduit et possède une zone à section transversale réduite pour restreindre le flux de fluide s'écoulant dans le conduit et permettre ainsi une mesure fiable du flux. Un circuit intégré ou un dispositif de commande peut être couplé à la soupape de commande et également couplé aux capteurs de pression par une structure de conducteurs comportant des conducteurs de signaux entourés par une cage de Faraday, et un boîtier chimiquement inerte est couplé au corps monobloc de régulateur contenant la soupape de commande et les capteurs de pression.
