ORIFICE PLATE CARRIER

An orifice plate carrier (70, 305) for positioning an orifice plate within an orifice fitting (12) to measure fluid flow rate through a conduit is disclosed. In some embodiments, the plate carrier (70, 305) has an opening (225) therethrough and an inner surface (207) surrounding the opening (225). A...

Zusammenfassung:	An orifice plate carrier (70, 305) for positioning an orifice plate within an orifice fitting (12) to measure fluid flow rate through a conduit is disclosed. In some embodiments, the plate carrier (70, 305) has an opening (225) therethrough and an inner surface (207) surrounding the opening (225). A lip (230) extends radially from the inner surface (207) to support an orifice plate assembly (72) with an orifice plate disposed therein. At least one flow port (220, 315) extends through the body (205). Each flow port (220, 315) is configured to allow fluid therethrough and to reduce a pressure differential between fluid up and downstream of the orifice plate during installation and extraction. At least two notches (235), each notch (235) extending radially from the inner surface (207), engage the orifice plate and maintain the concentric position of the orifice plate within the fitting (12). Se describe un soporte de placa con orificios (70, 305) para colocar una placa con orificio dentro de un accesorio con orificio (12) para medir la velocidad de flujo de fluido a través de un conducto. En algunas modalidades, el soporte de placa (70, 305) tiene una abertura (225) a través de él y una superficie interna (207) que rodea la abertura (225). Un labio (230) se extiende radialmente desde la superficie interna (207) para soportar una unidad de placa con orificio (72) con una placa con orificio, dispuesta en la misma. Por lo menos un puerto de flujo (220, 315) se extiende a través del cuerpo (205). Cada puerto de flujo (220, 315) está configurado para permitir que el fluido pase a través de él y para reducir un diferencial de presión entre el fluido arriba y abajo de la placa con orificio durante la instalación y extracción. Al menos dos muescas (235), cada muesca (235) se extiende radialmente desde la superficie interna (207), engancha la placa con orificio y mantiene la posición concéntrica de la placa con orificio dentro del accesorio (12).
