2、 Functional features:
1. The transmission part adopts our company's self holding switch technology to ensure the accuracy of signal transmission.
2. The table and signaling counting parts adopt a separate structure, and any damage to one part does not affect the reuse of the other part, making maintenance convenient.
3. Adopting advanced domestic RS485/MBUS design technology and equipped with a watchdog phone, it ensures the stability and reliability of communication.
4. The messaging part adopts a stainless steel shell and a shielding layer, which can effectively prevent magnetic field interference and prevent users from stealing water.
5. The sending part adopts a fully sealed structure, which can prevent moisture and water.
6. Readings can be designed to be accurate to 0.001m ³, 0.01m ³, 0.1m ³, and 1m ³ of water according to user needs.
7. Equipped with short line and break detection functions, it can monitor users' abnormal water usage status in a timely manner.
8. The service life can reach ten years.
