Water metering

Water metering is the process of measuring water use.

In many developed countries water meters are used to measure the volume of water used by residential and commercial building that are supplied with water by a public water supply system. Water meters can also be used at the water source, well, or throughout a water system to determine flow through a particular portion of the system. In most of the world water meters measure flow in cubic metres (m) or litres but in the USA and some other countries water meters are calibrated in cubic feet (ft.) or US gallons on a mechanical or electronic register. Some electronic meter registers can display rate-of-flow in addition to total usage.
