Product features
Periodic reporting: By default, data is uploaded every 24 hours, with discrete time intervals to ensure that all remote water meters within the project area can upload data normally;
Upload data content: The data includes NB signal data, periodic sampling data, uploaded current sampling data, alarm data, battery voltage, and NB module information;
Bluetooth reporting: Add Bluetooth channel to enable the water meter to upload current data;
Data storage: In case of power outage, the data in the table must be stored for at least ten years; Can ensure automatic data recovery after power on again; Alarm function: When the remote water meter experiences low battery voltage, storage failure, or sampling;
Report abnormal data to the backend system when problems such as malfunctions or valve malfunctions occur;
Valve control: The opening and closing of water meter valves can be controlled remotely or by handheld devices.
