EMUE-D4-2-OrificePlate

The report shows how the uncertainty should be evaluated for a measurement from an orifice meter where the flowrate is evaluated using a discharge-coefficient equation based on data from a population of orifice meters: the orifice meter in service is not itself calibrated in a flowing fluid, but is similar (with permitted variability) to those on which the discharge-coefficient equation is based.

The data on which the discharge-coefficient equation in ISO 5167-2:2003 (the Reader-Harris/Gallagher (1998) Equation) is based are given in the uploaded dataset together with the analysis required by the report (to follow).

Files contained in the dataset are:

D4-2_Report.pdf: Report “The uncertainty of the orifice-plate discharge coefficient”

D4-2 LaTeX Source Files.zip: LaTeX files to be compiled in order to produce D4-2_Report.pdf.
