Title
(EN) ELECTROSTATIC SPRAYER IN-LINE FLOW MEASUREMENT ARRANGEMENT
(FR) AGENCEMENT DE MESURE D'ÉCOULEMENT EN LIGNE D'UN PULVÉRISATEUR ÉLECTROSTATIQUE
Abstract
(EN) An in-line instantaneous direct flow rate measurement arrangement for an electrostatic spraying system is described. The arrangement includes a liquid feed stock line (125) supplying a liquid feed stock (115). The arrangement further includes an electrostatic spray nozzle assembly including: a spray nozzle (130) and an electrode (140) configured to provide an electrical charge potential to the liquid feed stock (115) emitted by the spray nozzle (130). The arrangement also includes an in-line instantaneous flow rate measurement arrangement comprising: an electrically isolating pipe segment (155); and an in-line instantaneous flowmeter (150) configured to sense a flow rate of the liquid feed stock (115) passing through the electrically isolating pipe segment (155).
(FR) L'invention concerne un agencement de mesure de débit direct instantané en ligne pour un système de pulvérisation électrostatique. L'agencement comprend une conduite à charge d'alimentation liquide (125) fournissant une charge d'alimentation liquide (115). L'agencement comprend en outre un ensemble buse de pulvérisation électrostatique comprenant : une buse de pulvérisation (130) et une électrode (140) conçue pour fournir un potentiel de charge électrique à la charge d'alimentation liquide (115) émise par la buse de pulvérisation (130). L'agencement comprend également un agencement de mesure de débit instantané en ligne comprenant : un segment de tuyau électriquement isolant (155) ; et un débitmètre instantané en ligne (150) conçu pour détecter un débit de la charge d'alimentation liquide (115) passant à travers le segment de tuyau électriquement isolant (155).
