  • Optional communication protocol: support"urban fire remote monitoring system protocol - GB26875"
  • Industrial grade design: wide temperature design,high and low temperature resistance, suitable for various harsh sites
  • Large-capacity data storage space:Provide 2MB data storage space, which can store more than 5 years of collected data
  • Multiple communication methods: NB-IOT/LoRa/ LORaWAN and other communication methods
  • Low power consumption design:support multiple working modes(including self-reporting, querying, compatible, etc.) to minimize power consumption
  • Local configuration mode: support serial port/Bluetooth configuration mode
  • Remote management function: support remote parameter configuration and remote program upgrade. Provide powerful central management software to facilitate device management(optional)

Main Function of Product

  • Automatically and regularly collect data such as the water pressure and water level of fire hydrants at the metering point to achieve the accuracy completeness timeliness and reliability of data collection
  • Regularly report fire hydrant water level status, battery power,signal strength and other data
  • Built-in lithium battery power supply(38Ah/57Ah optional), can also support external power supply multiple power management modes
  • The equipment can realize the self-inspection of the power supply voltage and equipment status, analyze information such as faults, and find abnormalities in time
  • Support battery voltage reporting function
  • Comes with a screen,which can display data such as networking status, current liquid level value, battery voltage, etc. The screen is 128*64 dot matrix
  • The range of the liquid level transmitter is optional, and the default configuration is 5 meters
