Types of meters
There are two major methods of flow measurement in use,


with sub-technologies within each of them. Common displacement designs include oscillating piston and nutating disk meters. Velocity-based designs include single- and multi-jet meters and turbine meters. There are also non-mechanical designs, for example electromagnetic and ultrasonic meters.

In addition to the more common types of meter, there are meters designed for special uses. Most meters in a typical water distribution system (http://en.wikipedia.org/wiki/Water_supply_network) are designed for cold potable water (http://en.wikipedia.org/wiki/Potable_water) only. There are specialty water meters manufactured for specific other uses. Hot water meters are designed with special materials that can withstand higher temperatures. Meters for reclaimed water (http://en.wikipedia.org/wiki/Reclaimed_water) have special lavender register covers to signify that the water is non-potable and should not be used for drinking.

Water meters are generally owned, read, and maintained by a public water provider such as a city, rural water association, or private water company. In some cases an owner of a mobile home park, apartment complex or commercial building may be billed by a utility on one meter, and want to share the cost of the bill among the tenants. In this case, private meters may be purchased to separately track usage of each unit in what is called submetering (http://en.wikipedia.org/wiki/Utility_submeter).
