Meter Set Assemblies consist of four parts. Which is the correct list?

• A. Gas Meter; Piping; Shut off valve; Regulator
• B. Piping; Shut off valve; Regulator; Gas Meter
• C. Piping; Valve; Regulator; Gas Meter
• D. Piping; Shut off valve; Regulator; Service Line

Answer: (B)

A meter set assembly is built from four essential components that work in a sequence from the supply toward the building: piping, a shut-off valve to isolate the system, a regulator to reduce the gas pressure to safe levels, and the gas meter to measure usage. The piping carries the gas into the assembly; the shut-off valve lets you quickly stop flow for safety or service; the regulator steps the high incoming pressure down to a safe, usable pressure for the house; and the meter records how much gas is consumed as it moves toward the building’s piping. This order reflects how gas travels through the assembly and ensures safety, proper pressure, and accurate measurement. The other options either omit a required component (the shut-off valve or the meter), use a non-specific valve instead of a shut-off one, or misplace the service line, which would not align with how meter set assemblies are structured.
