Standard volume calculation with our Z-factor correction

Compressibility factors are an important basis for correctly billing gas volumes. Because natural gas does not behave like an ideal gas due to its intermolecular interactions, compressibility factors are required for calculations of standard volume from the measured volume in the operating state.

We would be pleased to perform calculations and plausibility checks (Z-factor) as well as calculations and plausibility checks of Z-factor corrected standard volume load curves – reliably and according to the currently valid DVGW Code of Practice G 685-6 according to AGA8-92 DC.
