A water meter is a device used to measure the volume of water consumed by a household, business, or industrial facility. It is typically installed within the water supply line entering a property and is connected to a network of pipes carrying water from the utility provider. Water meters come in various types, including mechanical, electronic, and smart meters. Mechanical meters feature rotating dials or discs that measure water flow based on the movement of internal components. Electronic meters use sensors and digital displays to measure water usage, while smart meters can communicate usage data remotely to the utility provider for billing and monitoring purposes.
