Paper Abstract

In order to improve the measurement accuracy of cylinder shell resonating density meter, the paper presents many means of methods to lower the measurement error from the liquid temperature, pressure, viscidity and gas bubble in the liquid, and designs a novel cylinder shell resonating density meter. Taking typical calibration experiments as example, the paper gives the detailed steps of calculating uncertainty component of the cylinder shell resonating density meter, and values the combined uncertainty. The experiments and analysis show the combined uncertainty is 0.96kg/m3 when the measurement result is 785.16 kg/m3, and the relative uncertainty is 0.12%.
