Abstract
An orifice plate assembly for use with a process variable transmitter for measuring flow of a process fluid includes a single piece body having a circumferential support ring. A first face of the circumferential support ring is configured to be sealingly coupled to a first flange of a first process pipe. A second face of the circumferential support ring is configured to be sealingly coupled to a second flange of a second process pipe. A flow plate region is positioned between the first and second pipes and has first and second sides. The flow plate region is concentric with the circumferential support ring. At least one flow orifice in the flow plate region provides a restricted fluid path between the first and second process pipes. A first pressure tap is configured to fluidically couple to the process variable transmitter to the process fluid proximate the first side of the flow plate region. A second pressure tap configured to fluidically couple the process variable transmitter to the process fluid proximate the second side of the flow plate region.
