The amount of water used in industrial and residential buildings is determined by water flow meters. A municipal water delivery scheme provides water to households and businesses.

The flow concentrations of a section of the system may also be measured by using water metering at water supplies or in the water system. Flowmeters, the flow velocity of slurries, or fluids may be determined in closed pipes as well. The water flow velocity is calculated in the electronic or mechanical register of cubic meters (m3) or litres.
