Application of a novel method for validating the uncertainty estimation of a flow test facility

摘要

After a large heat meter flow test rig was overhauled, making a thorough characterization and revalidation of the associated uncertainty is necessary. Validating the uncertainty through interlaboratory comparisons takes years and is not always successful. Therefore, a method is proposed to validate the uncertainty estimation based on a flow meter Reynolds number similarity in between comparisons. The newly estimated uncertainty of an overhauled facility is schematized and the proposed method is applied. The obtained results are confirmed through a conventional international interlaboratory comparison.
