What is a requirement for meters installed to measure usage for water metering?

The requirement for meters installed to measure usage for water metering is that they must be permanently installed. This is essential because permanent installation ensures that the meter provides consistent and accurate measurements over time, which is crucial for effective water management and conservation efforts. Permanently installed meters allow for continuous monitoring, enabling building operators to track water usage patterns, identify leaks or inefficiencies, and implement strategies for reducing consumption. Real-time data, while beneficial, is not a strict requirement for all water meters, and the necessity for portability or annual updates does not align with the need for stable and ongoing measurement in water management practices.
