Which factor can cause a gas meter to malfunction?

The accumulation of dirt and corrosion is a significant factor that can lead to a gas meter malfunction. Over time, contaminants can build up inside the meter, affecting its internal components and mechanisms. When dirt or corrosion obstructs the meter, it can cause inaccurate readings, slow or erratic operation, and ultimately lead to failure in measuring gas flow correctly. Regular maintenance and inspections are essential to ensure that the meter remains clean and free from obstructions, contributing to its proper functionality and longevity.

On the other hand, while excessive pressure, temperature fluctuations, and insufficient gas supply can contribute to various issues in a gas system, they do not directly relate to the physical obstructions or build-up within the meter that dirt and corrosion present. Therefore, the presence of dirt and corrosion specifically highlights a key issue that can affect the operational reliability of gas meters.
