Algorithm MR113n
MR113n is an algorithm for calculating the molar mass and other gas characteristics which
is widely used for measurement of associated gas in Russia.
The algorithm is adapted better to the typical application conditions of this industry. The
calculation of molar mass, compressibility and other characteristics is based on a known
gas matrix with 14 components.

The gas composition can be configured with constant values or read in by a gas
chromatograph. Various types can be selected in the operating software.
The algorithm provides the most exact results when a gas chromatograph is available.
Nitrogen compensation
Nitrogen compensation is available when using the carbon number algorithm.
In applications that inject nitrogen before the measuring device in order to ensure
permanent purging, these nitrogen quantities are also recorded.
