Abstract

The design and the expected performance of a new apparatus suitable to satisfy the traceability requirements in the density field is here presented. The apparatus is mainly intended to measure liquid density range between 500 kg/m3 and 3000 kg/m3 and to evaluate the performance of on-line densimeters during the actual use, i.e. the same process liquid under similar flow conditions. Details about the hardware components of the system and the software programs are also given. By using an instrument not specifically selected and calibrated for the intended working conditions, the value of (p)=0.20 kg /m3 instr u is the lowest expected uncertainty of density measurements of fluids. However, higher accuracy can be established for the selected reference instrument by the use of the same fluids employed in the process at the usual operative conditions and whose densities are certified by national metrological institutes (NMIs) or accredited laboratories.
