Liquid Orifice Meter Plate CalculationLiquid orifice plate calculations are based on the ReaderHarris Gallagher equation for the orifice coefficient found in the Third Edition of the Manual of Petroleum Measurements Standards, Chapter 14  Natural Gas Fluids Measurements, Section 3  Concentric SquareEdged Orifice Meters, Part 3  Natural Gas Applications. Oifice bore is corrected back to a room temperature of 20°C (or 68°F). The bore input or calculated is the bore measured at the orifice manufacturer's shop at room temperature. Note that when solving for orifice bore the calculations may not converge for a beta ratio greater than 0.8. References: Liquid Orifice Meter Plate CalculationCopyrighted 2002, 2003
