What is the recommended testing interval for large meters?

The recommended testing interval for large meters is every 1-4 years. This timeframe helps ensure that meters remain accurate in their measurements and can effectively monitor water usage, billing, and resource management. Regular testing within this interval helps identify any potential issues early on, allowing for timely maintenance or replacement that can prevent larger problems down the line. Frequent calibrations are particularly important for large meters, as even slight inaccuracies can lead to significant discrepancies in billing, efficiency assessment, and overall utility management.

The other intervals, while they may apply to different types of meters or less critical systems, are not aligned with best practices for large meter management, which prioritize accurate and reliable data collection to maintain operational integrity.
