Abstract
A differential pressure fluid flow meter measures flow of a fluid based upon a differential pressure. An orifice plate is selected from a plurality of orifice plates configured to be positioned between upstream and the downstream taps in the conduit. Four evenly spaced circular orifices allow the flow of fluid there through and create the differential pressure which is a function of fluid flow rate. Xis a distance in a direction perpendicular to an axis of the conduit from the nearest outer circumference of the circular orifices to a projection of a center of the downstream tap on the flat orifice plate. Xis a distance between outer circumferences of two opposed circular orifices. Ris a ratio of the diameter that locates the centers of the four circular orifices and the interior diameter of the conduit. Xand Xare each a function of R.
