Gas meter. A gas meter is a specialized flow meter, used to measure the volume of fuel gases such as natural gas and liquefied petroleum gas. 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, because measured volumes are ...
Typical old-style fuel gauge on a 50 ccm chinese-made scooter from 2008, with the internationally used pictogram of a gas pump. The system can be fail-safe. If an electrical fault opens, the electrical circuit causes the indicator to show the tank as being empty (theoretically provoking the driver to refill the tank) rather than full (which ...
A gas meter measures energy indirectly by recording the volume of gas used. This figure can then be converted to a measure of energy by multiplying it by the calorific value of the gas. Power (flux of energy)
Components of a custody transfer system typically include: Multiple meters/meter runs; Flow computers; Quality systems (gas chromatographs to measure energy content of natural gas and sampling systems for liquid); Calibration using in-place or mobile provers for liquid, or master-meter for liquid or gas; and; Supporting automation.
The IFGC protects public health and safety for all building systems that use fuel gas for the design, installation and inspection of such systems by providing minimum safeguards for people at homes, schools and workplace. Fuel burning appliances, furnaces, chimneys, vents, gas pipe sizing and many other such issues are addressed in the IFGC.

Provers work by passing a known volume of air through a meter, while monitoring the gas meter's register, index, or internal displacement.
