Liquid Piston Prover Uncertainty Analysis Spreadsheet



John D. Wright, Aaron N. Johnson, Jodie G. Pope


This publication is a spreadsheet that calculates the mass and volume flow uncertainty for a piston prover liquid flow standard based on user inputs of component uncertainties. The calculations use the basis nist-equation and uncertainty analysis presented in NIST SP 250-1039r1. An Instructions worksheet and comments on individual cells of the spreadsheet guide users and suggest how to estimate the magnitude of uncertainty components. Contact,, or to obtain a copy of the spreadsheet, for explanations, to make comments, or to suggest improvements.
