A water meter is a device that measures the volume of water used at your home. Water meters are almost always installed by the local water utility. Depending upon the utility, some water meters are the property of the homeowner and some are the property of the utility.
If you are interested in installing an additional water meter in your home, perhaps to monitor a specific water use such as irrigation, a swimming pool, or a water treatment device, contact a professional plumber. Installation of a water meter requires cutting pipes, sweating pipes together, and other plumbing tasks.
