The structure of smart water meter mainly includes the following parts:

Base meter: Usually a mechanical rotor-type water meter, responsible for basic water measurement.

IC card reader: Used to exchange data with IC card to read and write the amount.

Microcomputer module: Core control unit, responsible for processing IC card data, measuring water consumption, controlling valve switch, etc.

Electronic control valve: Control water supply according to the instructions of microcomputer module.

LCD display module: Displays information such as remaining water and water consumption to users.

Sensor: Water collection device, responsible for collecting and converting water consumption data.

Water filter: Prevent impurities from entering the water meter movement and causing water meter failure.

Case, middle cover, watch glass: Constitute a sealed body to prevent the measured water from leaking out of the meter.

‌Measuring mechanism‌: Including gear box, impeller box, integral impeller, etc., is the "heart" of the water meter and plays a key role in the metering performance and durability of the water meter‌.
‌Counting mechanism‌: Common forms include pointer type, word wheel type and pointer word wheel combination type‌
