The natural gas meter set includes many parts that work together to safely deliver and measure natural gas to a structure. This can include the meter, valves, fittings, a meter bar or valve, a regulator, and the accessories that complete the set.


Through the natural gas journey, one of the main focuses is lowering gas pressure in order to fit the appliance needs for a consumer. The transition to usage means reducing as much as 60+ PSI all the way down to one quarter of a PSI that gas appliances operate at. The natural gas meter set helps safely achieve this pressure, but it is the gas utility’s responsibility to install and maintain the gas meter set.


For both safety and testing purposes, some natural gas valves include a tap on the valve itself. This allows gas utilities to conduct the following tasks:

Check/monitor system pressure

  • This allows the utility to get a reading of gas pressure delivered before or after the regulator

An opportunity for a field technician to do the following:

  • Install a gauge before the regulator that will measure in PSI, typically up to 60 PSI or beyond
  • Install a gauge after the regulator that will measure in inches of water column or about 2 PSI
  • Perform bypass on a natural gas meter set
