1.Water meter adopts mechanical and electrical separation structure design, simple installation and construction in the early stage, convenient maintenance and replacement in the later stage;
2.Using dual-Hall sensor design, the minimum measurement unit is 100L, which can realize the forward and reverse measurement of the water meter and ensure the complete synchronization of the electromechanical system;
3.Water meter data is transmitted through the NB-IOT IoT dedicated network, and the data is safe and reliable;
4.Periodic reporting: Periodic reporting every day. The 24-hour data of the previous day can be reported. You can set or change the sending frequency through the platform to minimize the reporting every hour. The data includes data recorded every 30 minutes, a total of 48 recorded information, etc. ;
5.Support manual reporting function
6.Replenishment function: When the data report is unsuccessful, the data will be replenished automatically in the next reporting period, and the data can be replenished during the effective data retention period;
7.Setting function: parameter setting can be performed through the application platform or handheld device;
8.Reporting and resending mechanism settings: data reporting is unsuccessful, water meter data is resent, and resending times can be set;
9.Time proofreading: When the data is reported periodically, the water meter can be proofreaded;
10.Data encryption: encrypt the transmitted data;
11.The water meter detects magnetic interference and low battery voltage, and actively uploads abnormal alarms to the meter reading platform for real-time monitoring;
12.Unified development interface, can support multi-vendor, multi-device integration, easy for later maintenance;
13.6 years of module communication costs are pre-stored in the water meter before leaving the factory.
Data storage: 60 days of data can be stored, when the storage medium is full, the newly collected data automatically overwrites the earliest data;
