Existing methods of calculating the Joule–Thomson coefficient for natural gas are analyzed. A procedure for use in calculations of gas flow rate employing the variable pressure drop method is proposed which gives increased measurement accuracy by eliminating the additional error in determining the temperature of the natural gas.
