What is a Smart Water Meter?

Smart water meter is a new type of water meter that uses modern microelectronics technology, modern sensor technology, and smart IC card technology to measure water consumption, transmit water consumption data, and settle transactions. Compared with traditional mechanical water meters, smart water meters not only have the functions of flow collection and mechanical pointer display of water consumption, but also have functions such as electronic display, remote transmission, automatic control, and data storage. ‌

The main types of smart water meters include mechanical water meters with electronic devices and electronic water meters. Mechanical water meters with electronic devices add electronic devices to traditional mechanical water meters, such as pulse type and direct reading type, which can realize remote data communication. Electronic water meters measure flow through electromagnetic and ultrasonic principles. Common types include ultrasonic water meters and electromagnetic water meters. These water meters have no mechanical moving parts and have higher measurement accuracy and wider measurement range.

The advantages of smart water meters include no need for manual meter reading and charging, high security, anti-magnetic attack, warning and overdraft functions, power-off memory function, etc. In addition, smart water meters can also calculate water charges for tiered water prices, and use IC cards for data transmission and transaction settlement, allowing users to switch from door-to-door meter reading and payment to self-payment.
