Abstract: This paper is a continuation of two previous papers on uncertainty analysis1,2. The first paper presented a simplified approach to the uncertainty analysis of a volume measurement based on an ultrasonic or turbine meter. The various components that contribute uncertainty were characterized based on manufacturers specifications. The second paper illustrated the interpretation of calibration results for inclusion into the uncertainty analysis. The development incorporated considerable discussion of the impact of systematic and random effects. This paper expands previously developed uncertainty analysis techniques from single to multiple meter based volume measurements. The development includes the concept of correlation and illustrates the effect on the overall measurement uncertainty. A statistical simulation technique is applied to implement the uncertainty analysis.
