A water meter is a device that measures the volume of water flowing through a pipe. Water meters are typically installed by water utilities to measure the amount of water used by customers, and are used to calculate water bills.
There are many different types of water meters, but the most common type is the mechanical water meter. Mechanical water meters have a dial that indicates the volume of water that has flowed through the meter. To check a mechanical water meter, simply read the dial and record the number of gallons or cubic feet of water that have been used.
