Intelligent IoT Smart Water Meter LXSY-TW Type Digital Water Flow 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 and convenient
installation, long service life, etc.
1. Split structure: The electronic unit is independent from the base table.
