Your benefits

  • Backwards compatible:
    No meter change required when migrating water and gas meters with GWFcoder® interface into a Low Power Wide Area Network (LPWAN)
  • Performance driven design:
    Range up to several km
  • Plug & Play:
    Easy and fast on-site installation with auto interface-detection and activation in LoRaWAN (no programming required)
  • LoRa Alliance Certified:
    Interoperable with different LoRaWAN network providers
  • Integrated monitoring of connectivity and reconnecting mechanisms:
    Robust operation with automatic repair options, e.g. with gateway failures
  • Custom-tailored RF Mode:
    Up to 15 years battery lifetime

Applications

  • Simple readout of water and gas meters with GWFcoder® registers without necessity to access buildings
  • Migration of installed meters with GWFcoder® registers to a smart metering system via LoRaWAN
  • Energy monitoring, energy reporting and consumption accounting with the GWF MEA cloud solution
  • Integration of water and gas meters with GWFcoder® registers in smart city projects

Properties

  • Battery powered, LoRaWAN radio module
  • Radio transmission in license free 868 MHz frequency band
  • Water proof design for pit installations (protection class IP68)
  • Transmission of latest register value and further information
  • For all meter types with GWFcoder® / GWFcoder® MP register with SCR(IEC) or ECO interface (gas / water, domestic and industrial meters)
  • Split-connection (cable) to the meter – remote installation
  • Data transmission in accordance with LoRaWAN specification
  • Data security via AES-128-bit end-to-end encryption over 2 independent security layers
  • ADR (adaptive data rate) support gives higher transmission intervals with consistent battery life
  • Real-time clock synchronization with the LoRaWAN-Network (Radio module version ≥1.4.0 and acc. LoRaWAN spec. ≥1.0.3 – DeviceTimeReq)
  • Infrared configuration interface
  • Approval
