Gas Measurement (GM Series)

This Standard covers the product requirements for primary diaphragm gas meters with a maximum flow rate in the range 6 m³h-1 to 160 m³h-1 that may be purchased for installation in domestic, commercial and industrial locations.

This standard contains guidance on the appropriate installation and usage of systems designed to convert gas volume readings to base conditions

The IGEM GM Series includes all the Gas Measurement standards.

This standard extensively details the requirements for the installation and usage of gas meters used in a non-domestic setting
