Verifying primary and secondary flow measurement performance

This article discusses a novel method to analyze the performance of the primary and secondary flow measurements by separating repeatability and accuracy (bias shift) without having to assume the PM is always accurate and repeatable and identifies whether the issue is with the PM or with the SM.
