NEW SOLUTIONS FOR METROLOGICAL PROVISION OF LIQUEFIED HYDROCARBON GAS DENSITY MEASUREMENT

摘要

Disadvantages are considered for metrological provision of measurement facilities for liquefied hydrocarbon gas density based on a calculation determination method for component composition using tabulated values of density for individual components. A new method is proposed using state standard specimens for the density of these gases, traced for a verification scheme to the state standard, and established for their certification, and also established for measuring liquefied phase density under working conditions.
