How often should small meters be tested?

Small meters should typically be tested once every 5-10 years to ensure their accuracy and reliability in measuring utility consumption. This timeframe is often established based on the operational lifespan of the meters and the level of usage they experience. Regular testing is crucial for maintaining fair billing practices, as inaccurate readings can lead to customer dissatisfaction and financial losses for utility providers. Since small meters are generally low-volume usage devices, the less frequent testing interval is sufficient to verify their functionality, while also balancing the cost and logistics of the testing process.
