The algorithms of determination of compressibility coefficient and density of clean substances (hydrocarbons) and their mixtures are developed. The methods of determination of properties which allow to calculate physical properties of gas mixtures (in particular natural gas) on the basis of the simplified data set are developed. Application of developed methods allows to decrease additional systematic errors of measurement of flow rate and volume of energy carriers.
