MUMBAI, India, Sept. 7 -- Intellectual Property India has published a patent application (202627085132 A) filed by Rosemount Inc. on July 11, 2026, for Flowmeter With Conditioning Orifice Plate.
Inventor includes Mesnard, David, R..
The application for the patent was published on September 04, 2026, under issue no. 36/2026.
Abstract: A differential pressure fluid flow meter measures flow of a fluid based upon a differential pressure. An orifice plate (30) is selected from a plurality of orifice plates (30) configured to be positioned between upstream and the downstream taps (10, 12) in the conduit (8). Four evenly spaced circular orifices (22) allow the flow of fluid there through and create the differential pressure which is a function of fluid flow rate. Xdc is a distance in a direction perpendicular to an axis of the conduit (8) from the nearest outer circumference of the circular orifices (22) to a projection of a center of the downstream tap (12) on the flat orifice plate (30). Xed is a distance between outer circumferences of two opposed circular orifices (22). Rb is a ratio of the diameter that locates the centers of the four circular orifices (22) and the interior diameter of the conduit (8). Xdc and Xed are each a function of Rb.
