- Abstract:
- In cooperation with Sartorius AG in Goettingen and the Vienna University of Technology, the Austrian Federal Office of Metrology and Surveying (BEV) has developed a test System for hydrostatic weighing and determining the density of liquids and solids, whereby mass comparators are automatically loaded alternately with weights and submerged plummets. With the load alternator for weights and plummets, the density of a liquid on one side and the density of a submerged solid (and therefore its volume) on the other side can be determined hydrostatically via direct comparison with Standard plummets and the applied substitution weights.
To determine consecutively the volume of E1 weights and plummets, additional a fully automatic handling system for a 1-kg mass comparators, a volume comparator was developed. Thus, the hydrostatic weighing principle can be applied for serial volume determination on masses from 1 g to 1 kg by direct comparison with a single volume reference (e.g., a silicon sphere). This prinziple is implemented with a newly developed, fully automatic insertion mechanism for both completely submersed weights and substitution weights.
Both Systems are used for the dissemination of density and volume by BEV as well as for testing and calibrating of liquids and plummets and determining the volume of weights in connection with the determination of mass scale.
The volume comparator is also used in other metrology institutes and in accredited calibration laboratories. - Download:
