5. Conclusion
Various methods can be used to calibrate and verify liquid flowmetry. Whether gravimetric, volumetric or by comparison with a standard flowmeter, each of them must be carefully analyzed in order to select the most appropriate method for a given problem. The variety of conditions of use, calibration and parameters influencing the measurement of the quantities of interest are all criteria for selecting the method best suited to the metrological need. The diversity of calibration and verification options available, whatever the need, is representative of the complexity of situations encountered on site. In all cases, traceability, the representativeness of calibration conditions and the establishment of a justified uncertainty balance will ensure the quality of the results obtained. The continuous improvement of technical and scientific resources, on the one hand, and progress in terms of legal,...
