Abstract:
A process flow device comprising:an instrument base coupleable to process instrumentation, the instrument base including first and second differential pressure openings; first and second differential pressure passageways coupled to the instrument base and in communication with the first and second differential pressure openings; a differential flow plate coupleable between pipe connections, the differential flow plate including: a flow conduit supporting a flow interrupter that separates the flow conduit into two sides; a first pressure tap opened to the flow conduit on a first side of the flow interrupter and in fluid communication with the first differential pressure opening through the first pressure passageway; a second pressure tap opened to the flow conduit on an opposite side of the flow interrupter and in fluid communication with the second differential pressure opening through the second pressure passageway; and wherein the flow conduit is seamless between the flow interrupter and at least one of the first and second pressure taps.
