【 摘 要 】

A flow meter can be calibrated by different methods. To obtain minors measurements uncertainties, the laboratories use the weighing method; however, this method does not provide a simple operation, a specific apparatus has been developed for this calibration. Another approach is the calibration by volumetric method, using a tank prover as standard. This paper show the results obtained by this two different methods for the same flow meter. Key words: flow meter, weighing method, volumetric method, measurement uncertainty, innovation.
