The primary function of a gas meter in a gas heating system is to measure gas consumption. This allows users and utility companies to track how much gas is being used over a certain period, typically for billing purposes. Accurate measurement is essential for ensuring that customers are charged appropriately based on their actual usage.

Gas meters serve an important role in energy management, helping homeowners and businesses monitor their gas usage patterns and make informed decisions regarding consumption and efficiency improvements. They can either be mechanical or digital, but both types effectively fulfill the task of quantifying gas flow to provide a clear picture of gas usage.

The other functions mentioned do not pertain to the role of a gas meter. Filtering gas impurities would typically be handled by a filtration system prior to the gas reaching the meter. Increasing gas pressure is generally achieved through pressure regulators in the system. Regulating exhaust flow is a function of the venting system and is not related to the measurement of gas consumption.
