Discharge coefficients of orifice plates : Determination in natural gas under reference conditions (EEC - Phase 2)
This report describes the calibration of four of the EEC 100 mm plates in natural gas in the Gaz de France test facility, using all three sets of pressure tappings. The instrumentation - calibrated nozzles, pressure and differential pressures, temperature and density - is described in detail, as well as methods of calculation and detailed tests and results. Even taking into account expected uncertainties, the values obtained generally fall within the established ISO limits.
