Density determinations of liquid samples by density meters

Project Description

The aim of this comparison is, to research, eliminate or to pinpoint discrepancies between the frequently used density meters by NMIs  and the density determination by  hydrostatic weighing of standards, used as a national standard. Furthermore to establish an “official” link between the density determination by the hydrostatic weighing and the density meters. This project supposed to support the discussion about the criteria of the acceptability of density meters in metrological affairs.

The participants will have to determine the density of 3 different liquid samples (760 kg/m3 to 1000 kg/m 3) at different temperatures (15 °C to 40 °C) using their own density meters..

BEV will pilot this project; supported by MKEH

BEV and MKEH will establish the link to the hydrostatic weighing: registered as EURAMET project 1019 "Comparison of liquid density standards" registered in the KCDB: EURAMET.M.D-K2

BEV and MKEH will carry out additional tests including the density determination by hydrostatic weighing, the analysis and reporting.

Final Report 2016-04-07

The comparison has been completed and results are published in the KCDB.
