Gas meters are used at residential, commercial, and industrial buildings that consume fuel gas supplied by a gas utility.  Gases are more difficult to measure than liquids, as measured volumes are highly affected by temperature and pressure.  Gas meters measure a defined volume, regardless of the pressurized quantity or quality of the gas flowing through the meter." ] ,
