What is the acceptable accuracy range for small water meters at 15 psi?

The acceptable accuracy range for small water meters at 15 psi typically falls between 98.5% and 101.5%. This range indicates that the meter should measure within 1.5% above or below the actual water flow—indicating a high degree of precision essential for accurate billing and monitoring water consumption.

This level of accuracy is crucial for maintaining customer trust and ensuring the proper functioning of the water distribution system. When meters fall within this range, they are deemed to provide reliable measurements that reflect true water usage without significant deviation. Accurate water meters reduce the likelihood of revenue loss due to under-registration or over-registration of water usage.

In contrast, the other options present wider ranges or percentages that do not meet the standards for small water meters. Meter readings that are less precise may lead to discrepancies in revenue and customer service issues, which is why adhering to the specified accuracy range is vital in water distribution management.
