Orifice uncertainty
WitrynaOrifice meters often do not handle a large range of flow rates. more_vert Thus, one can manufacture an orifice meter of known uncertainty with only the measurement … WitrynaMinimum uncertainty of the orifice plate coefficient of discharge ( C d ) is achieved with βr between 0.2 and 0.6 and orifice bore diameters greater than or equal to 0.45 inch. Diameter ratios an d orifice bore diameters outside of this range may be used; the user should consult the uncertainty section in API MPMS
