What are the functions of IoT cards?
Smart water meters have ushered in a brand-new era of intelligent technology, replacing mechanical water meters and making our lives more convenient and efficient. They’ve received unanimous praise from everyone. Recently, many friends have been asking about the roles that IoT cards play in smart water meters.
1. The smart water meter uses an IoT-specific IoT card with a dedicated network and dedicated number, providing a secure communication channel based on IoT technology. It features advanced encryption technology, ensuring stable, efficient, and secure communications.
2. Implement tiered water pricing with two compatible management mechanisms—prepaid and postpaid—and up to six tiers of water rates. Tiered water pricing is a national policy aimed at encouraging everyone to conserve water.

3. Based on the backend management system of the Wuliang network card software, you can instantly check the status of water fee applications at home from the backend, and you can also remotely control key parameters and achieve remote meter reading.
4. IoT cards have a long service life and can be used for extended periods without the need to replace batteries, giving customers peace of mind and confidence in their use.
I hope this helps everyone. If you have any further questions, feel free to ask—I’m always here to help!
