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… WebJan 4, 2024 · The Reader-Harris/Gallagher (1998) equation for corner tappings given in ISO 5167-2:2003, 5.3.2.1. should be used for deriving the discharge coefficients, provided the pipe Reynolds numbers are within. the limits given in ISO 5167-2:2003, 5.3.1. An additional uncertainty of 0,5 % should be added arithmetically to the uncertainty derived from
