A water meter is a device that measures the amount of water a consumer is using. Most developed countries use water meters to measure the amount of water used by a commercial or residential building. They can also be used in a well, source of water, or water system to determine the flow of water through a specific part of the system. Different types of water meters are currently being used. However, the option depends on the accuracy requirements, the required flow rates, the end-user, and the flow measurement method.
