Abstract
Rational use of resources in heat and water supply systems and other industries is impossible without reliable measurement results of fluid consumption. The reliability of the measurement results is confirmed by their traceability to national standards. To ensure the traceability of flow standards, which cannot be directly connected to the national standard, it is necessary to carry out a comparison using a transfer standard. The main results of interlaboratory comparisons of fluid flow standards are considered. Comparisons, the pilot of which was State Enterprise Ukrmetrteststandart, carried out with the participation of Firm Sempal CO LTD, Kiev. The aim of the project was to carry out comparisons in the field of flow measurements between water meter calibration laboratories. Based on the results of comparisons, it was established: there are no significant deviations of the real parameters from those specified in the instructions; according to the agreed range of comparisons for flow rates from 13 m3/h to 350 m3/h, all the results of the installations are in good agreement; degree of equivalence Laboratory to CRV and Laboratory to laboratory Ei ≤ 1, laboratories are in good agreement; all results are completely satisfactory with a degree of equivalence less than 1.
