Patent number: 8215340Abstract: An orifice plate carrier for positioning an orifice plate within an orifice fitting to measure fluid flow rate through a conduit is disclosed. In some embodiments, the plate carrier has an opening therethrough and an inner surface surrounding the opening. A lip extends radially from the inner surface to support an orifice plate assembly with an orifice plate disposed therein. At least one flow port extends through the body. Each flow port 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, each notch extending radially from the inner surface, engage the orifice plate and maintain the concentric position of the orifice plate within the fitting.Type: GrantFiled: February 19, 2008Date of Patent: July 10, 2012Assignee: Daniel Measurement and Control, Inc.Inventors: Thomas Henry Loga, Ronald Doom, Darren Scott Schwarz, Gerald Wayne Blankenship, Robin C.
