WebApr 1, 2011 · The Reader-Harris/Gallagher and prior equations such as the Stolz [16] are empirically derived by attempting to match the correction needed for the ideal square root relation to geometric and Re factors of the actual orifice device, so that the measured flow rate matches that calculated from Eq. (3b). Flow rates through an orifice plate can be calculated without specifically calibrating the individual flowmeter so long as the construction and installation of the device complies with the stipulations of the relevant standard or handbook. The calculation takes account of the fluid and fluid conditions, the pipe size, the orifice size and the measured differential pressure; it also takes account of the coefficient of discharge of the orifice plate, which depends upon the orifice type a…
