What is the maximum allowable tolerance for maintenance of CNG meters?

The maximum allowable tolerance for the maintenance of CNG (Compressed Natural Gas) meters is set at +/- 2.0%. This standard is important because it ensures accuracy in measuring the volume of gas delivered and complies with regulatory requirements. A tolerance of +/- 2.0% allows for minor fluctuations or errors in measurement while still ensuring that the system operates within acceptable limits.

Accurate meter readings are crucial for both billing purposes and regulatory compliance, and maintaining this tolerance helps prevent financial discrepancies between suppliers and consumers. Other tolerances listed, such as +/- 1.5%, +/- 2.5%, and +/- 3.0%, may not align with regulatory standards for CNG meters, which emphasize the importance of operational consistency and precision in the gas measurement industry.
