Natural gas service meters measure the amount of natural gas used in a structure. You will find these meters located both indoors and outdoors. Meters may be freestanding, single units or may be joined together in a group serving multiple premises, such as for apartment complexes.

On high-pressure and medium-pressure services, meter assemblies have a regulator between the service or meter valve and the meter. The regulator reduces the pressure of the gas from high to low so that it can be used by appliances and equipment.
