Abstract
The flowrate of a compressible gs is determined by measuring the pressure and temperature on each side of a flow impedance device, such as an orifice plate and computing the flowrate from the resulting pressure and temperature differentials according to a newly discovered orifice equation disclosed herein. The flowrate determined in accordance with the invention is more accurate than that calculated by using the standard orifice equation, which ignores the temperature differential. In addition, the calculation is independent of the type of flow impedance used and is not affected by degradation of the impedance device, such as the erosion of the orifice in orifice plates.
