Your benefits
- 2 communication technologies in one radio module (Dual-mode):
Investment security and efficient meter reading all the time with fall back to wireless M-Bus if LoRaWAN is not accessible - Plug & Play:
Backward compatible for all meter types with GWFcoder® MP. Easy and fast on-site installation with auto interface-detection (no programming required) - Performance driven design:
Range up to several km (LoRaWAN) and up to 600 m (wireless M-Bus) - Integrated monitoring of connectivity and reconnecting mechanisms (LoRaWAN):
Robust operation with automatic repair options, e. g. due to gateway failures - Custom-tailored RF mode:
Up to 15 years battery lifetime
Applications
- Simple readout of water and gas meters with GWFcoder® MP registers without necessity to access buildings
- Migration of installed meters with GWFcoder® MP registers to a smart metering system via LoRaWAN or wireless M-Bus
- Energy monitoring, energy reporting and consumption accounting with any cloud solution
- Integration of water and gas meters with GWFcoder® MP registers in smart city projects
Options
- RCM®-H200 compact (protection class IP67) – radio module builds compact on a water meter
- Only LoRaWAN or only wireless M-Bus
- Warnings, all disabled
