| Zusammenfassung | A magnetic flotation apparatus for determining the density of water over a wide temperature range is described. After a short discussion of the advantages of a magnetic flotation method against the hydrostatic weighing method, the apparatus built at the Physikalisch-Technische Bundesanstalt (PTB) is described in detail. Contributions to the measurement uncertainty are discussed. The functionality of the apparatus is demonstrated with a series of water density measurements at 20 °C. |
