Abstract

An orifice plate assembly including a plurality of ring members, each having an inner facing surface including a first annular recess extending therein, and a plurality of inner annular seals, whereina different inner annular seal of the plurality is overmolded to the first annular recess of each of the plurality of ring members to seal against a facing surface of an orifice plate captured between the plurality of ring members.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Patent Application Serial No. 14 / 824,246, entitled "Orifice Plate Assembly," filed August 12, 2015, the entire contents of which are hereby incorporated by reference. [0003] Statement Regarding Federal Funding for Research or Development [0004] Not applicable. Background technique [0005] Fluid flow is the quantification of the movement of a bulk fluid or gas, typically measured as volume flow and mass flow. The ability to reliably and accurately measure fluid flow plays an important role in a variety of processes and industries such as chemical processing, oil and gas transportation and production, and others. An orifice fitting is one of a variety of devices that can be used to measure the volume flow and mass flow of fluid flowing through a tube or pipe. Orifice fittings typically employ a flat, thin plate with a central hole that is smaller in diameter than the pipe i...
