Popis:	Formulas are given for the conditionally-constant values of density under standard conditions as well as for the dynamic viscosity and the adiabatic exponent. The dynamic viscosity and adiabatic exponent depend only on the natural gas temperature and pressure that we recommend be used for mass and volumetric flowrate measurements under standard conditions in gas distribution organizations. The paper considers the feasibility of correcting meter readings not by entering the daily conditionally-constant composition of natural gas into a calculator, but by correcting the readings of all the instruments participating in commercial operations during the accounting period. This would be done by using correction factors that depend on the density under standard conditions and fixed consumption patterns (absolute pressure and temperature of the gas).
