Red Seal Gasfitter — Class B Practice Exam

The primary function of a gas meter is to measure the volume of gas consumed. This measurement is crucial for utility companies to bill customers accurately based on the amount of gas they use. The gas meter records the flow of gas in cubic meters or cubic feet, allowing for precise consumption tracking over a billing period.

Monitoring gas pressure, controlling gas flow rate, and detecting gas leaks are important functions in the overall safety and management of gas systems but are not the primary purpose of a gas meter. Gas meters focus specifically on quantifying the volume of gas, which directly relates to usage and billing, rather than maintaining pressure, regulating flow, or identifying leaks.
