What is one of the uses of water meters besides metering consumption?

Water meters serve several important functions beyond merely measuring water consumption. One significant use is in detecting leaks within the plumbing system. When water is consumed normally, the flow through the meter remains relatively steady and predictable. However, if there is a leak, the water meter will register flow that exceeds what is typically expected based on usage patterns. This irregularity can help identify potential leaks, allowing for timely repairs, which can save water and prevent damage to property.

The other options, while related to water management, do not accurately reflect the primary additional use of water meters. Measuring temperature is not a function of standard water meters, nor do they filter water or regulate pressure. Each of these functions typically requires specific equipment designed for those purposes, rather than the fundamental operation of a standard water meter.
