Mechanical water meters are the measurement basis for all smart water meters. They measure and display the volume of water flow entirely through mechanical structures and do not require external power.

• Simple and sturdy structure: Pure mechanical structure without complex electronic components, with a theoretically long lifespan.
• Low cost: Manufacturing cost and purchase price are much lower than those of smart water meters.
• No power supply required: Operates by the power of water flow itself, unaffected by power outages.
• Easy maintenance: Usually, the base meter is directly replaced after a malfunction, with a low technical threshold for repair.

• Old residential areas with low requirements for management functions.
• Regions or projects with limited budgets.
• Used as the metering base for smart water meters in combination with electronic modules.

However, with the increasing demand for smart cities and refined management, pure mechanical water meters are gradually being replaced by a combination of "mechanical water meters + intelligent modules". The mechanical water meter is responsible for the most core and reliable metering task, while the intelligent module is responsible for achieving efficient data transmission and management functions. The combination of the two constitutes the cornerstone of modern water supply systems.
