Abstract: For nearly a decade the North American Fluid Flow M easurement Council (NAFFMC) has investigated a variety of ultrasonic m eter effects on both low and high-pressure ultrasonic meters. The NAFFMC is com prised of 5-6 industry experts that request testing be performed and subse quently published at the annual CEESI Ultrasonic Conference. During the 10+ years of the NAFFMCs existence, res earch has studied effects ranging from header designs, upstream piping config urations, various meter tube end-treatments, and inline filters. While this pap er examines some of the history behind the NAFFMC research, much of the data used f or the final analysis is not included in order to keep the paper to a manageable length. Thus this paper will summarize some of the tests, and then focus on the use of an ultrasonic meters diagnostics to determine the health and predict the meters uncertainty based on the diagnostic parameters
