Colorado Engineering Experiment Station (CEESI) has provided consulting services to the Bureau of Land Management (BLM) in the development of a measurement uncertainty calculator. The objective is to provide the industry with a standardized tool to evaluate the sources of uncertainty encountered when measuring gas flow. Sources include; the primary measurement device, secondary instrumentation, installation effects, etc. Quantifying these uncertainties is important due to new regulations being imposed on the industry.
Download instructions can be found on the U.S. Dept of the Interior, BLM Knowledge Resource Center online >> Oil and Gas Uncertainty Calculator V1.3.
Update 4/30/19: Shortly after I posted this link, CEESI removed references to this calculator from their website. Since then, I found what I believe to be this same software tool at the link above. –SPS, Editor
