What is the primary purpose of a gas meter in a gas furnace system?

The primary purpose of a gas meter in a gas furnace system is to determine gas consumption. This device measures the volume of gas that is delivered to the furnace, allowing both the utility company and the homeowner to monitor how much fuel is being used over a specific period. Understanding gas consumption is crucial for analyzing energy usage, managing costs, and conducting maintenance on the furnace. By tracking gas consumption, users can ensure their heating system operates efficiently and make informed decisions about energy conservation and furnace performance.

While options related to measuring airflow, regulating gas pressure, and monitoring temperature are vital in a furnace system, they are not the primary functions of a gas meter. The meter specifically focuses on gas flow and usage rather than those other operational parameters.
