ASME MFC-2M Measurement Uncertainty for Fluid Flow in Closed Conduits – Reaffirmed 2013
| Published By | Publication Date | Number of Pages |
| ASME | 1983 | 74 |
This Standard presents a working outline detailing and illustrating the techniques for estimating measurement uncertainty for fluid flow in closed conduits. The statistical techniques and analytical concepts applied herein are applicable in most measurement processes. Section 2 provides examples of the mathematical model applied to the measurement of fluid flow. Each example inches a discussion of the elemental errors and examples of the statistical techniques. An effort has been made to use simple prose with a minimum of jargon.
