Improving measurement capabilities for liquid density measurements
The aim of this work package is to develop measurement capabilities for the measurement of liquid density by hydrostatic weighing and by using oscillation‑type density meters. Hydrostatic weighing apparatuses are usually self‑made. Such an apparatus will be designed based on the PTB apparatus with additional information, about technically different realisations coming from the BEV-PTP and GUM apparatuses. Possible simplifications, and their influence on the measurement uncertainty, will be investigated. Guidance for making iterative improvements will be developed.
