Mechanical meters are devices used to measure various quantities, such as electricity, water, or gas consumption. They operate using physical mechanisms, like gears and dials, to display readings. These meters are often found in homes and businesses, providing essential data for utility billing and resource management. Unlike digital meters, which use electronic components, mechanical meters rely on moving parts to function. They are typically more durable and can operate without electricity, making them reliable in various conditions. Common types include water meters, gas meters, and electricity meters, each designed for specific measurement tasks.
