BARRERA GARCIA, Aníbal; CESPON CASTRO, Roberto  e  FEITO CESPON, Michael. Evaluation of uncertainty of measurement in the system of transfer by duct in the refinery - thermoelectric of Cienfuegos. Universidad y Sociedad [online]. 2019, vol.11, n.1, pp. 107-115.  Epub 02-Mar-2019. ISSN 2218-3620.

The research was carried out at the Cienfuegos Refinery, with the fundamental objective of evaluating the uncertainty of measurement in the fiscal measurement system and transfer of custody by pipeline. For its fulfillment, interviews, direct observations, review of documents, as well as mathematical statistical techniques of this type of study are used, such as the deterministic methods of classical statistics, combination of uncertainties with the Bayesian method of analytical solutions. (Law of propagation of uncertainty), control charts, among others. As fundamental results, the measurement uncertainty is evaluated based on the elements established in the Guide to the Expression of Uncertainty in Measurement and the cuban norm - Guide 1066: 2015 in the fiscal measurement system and custody transfer object of analysis, demonstrating that the primary element installed in the delivery point is stable over time and able to maintain its metrological characteristics, in addition to reduce the uncertainty of measurement.
