Abstract
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 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.
