Module 2. The Natural Gas Delivery System
Gas service meters
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 services, most 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 it can be used by appliances and equipment.
