Remotely connection/disconnection
Advanced low-frequency narrowband (470MHZ-510MHZ)
Wireless spread spectrum communication technology
Meter data can be remotely read and processed by classification
The LoRa Wireless Smart Water Meter is based on wet water meter and installed advanced low-frequency narrowband (470MHZ-510MHZ) micro-power wireless communication control module. The administrator sends meter reading instructions through the background, and the built-in wireless module of the water meter uploads the user's water consumption information to the smart gateway through wireless spread spectrum communication technology. The gateway connects with the energy efficiency management platform, so the meter data can be remotely read and processed by classification. Real-time online, remote control and intelligent energy efficiency management are available. It can be widely used in smart water construction, water supply companies and various water management departments.
The product performance index conforms to GB/T778-2018.
