Why must the gas meter be replaced when it expires?

The core reasons for the mandatory replacement of gas meters upon expiration are threefold: regulatory requirements, safety risks, and inaccurate measurement.

1.Regulatory requirements: According to the "National Verification Regulation JJG577-2012", gas meters using natural gas as the medium must not exceed a service life of 10 years. Additionally, the state mandates that gas meters undergo only initial verification and must be replaced upon expiration to ensure fair trade settlement.

2.Safety risks: After expiration, the interfaces and internal components of the meter may age and deform, potentially causing valve jamming, gas blockage, and even gas leakage, posing a threat to the safety of users' lives and property.

3.Inaccurate measurement: After expiration, the aging of internal components and mechanical wear of the gas meter can lead to deviations in gas consumption data, affecting the accuracy of measurement.
