LoRaWAN wireless digital prepaid brass magnet stop valve control meter magnet water meter
Description:
The lorawan prepaid Water Meter is a smart water meter based on the LoRaWAN standard communication protocol.It adopts LoRa wireless technology communication, which has the characteristics of long communication distance and convenient networking.It is convenient for remote meter reading and controlling, effectively reducing operator's door-to-door meter reading and improving meter reading efficiency.
The water meter adopts electron and mechanical separation structure design, which is free from magnetic interference and ensures accurate measurement. The base meter and the wireless acquisition module can be completely separated and run independently, which is convenient for installation and maintenance.
Features:
Fully electromechanical separation, easy for maintenance; Mechanical and electrical running separately without interference. easy for maintenance; Far more than RF cards,user-friendly,wireless network planning,handset reading.
