Lorawan Wireless Cold Hot Water Meter Remote Control Vertical Water Flow Meter Industrial Water Meter
LoRaWAN IoT water meter is composed of water meter base meter, electric ball valve (valve control), magnetoresistive sensor, MCU, wireless communication module, control circuit and other components. Mechanical and electrical separation structure design. High capacity lithium sub battery pack is used for power supply. It provides long-term stable energy guarantee for data acquisition, valve control and wireless data transmission. LoRaWAN wireless communication module is adopted. Through the spread spectrum communication technology, the user water data is actively uploaded (once a day by default) to the LoRa WAN gateway. The gateway will upload to the system data service center through LTE 4G network or Ethernet. The system has the advantages of long communication distance, large capacity, fast andconvenient installation, long service life, etc.
