Your benefits
- 2 communication technologies in one meter (Dual mode):
Investment security and efficient meter reading all the time with fall back to wireless M-Bus if LoRaWAN is not accessible - Utility grade and sustainable technology (robust & high grade wear resistant materials with brass body):
Excellent measuring stability and reliability over meter lifetime and awareness of using a recyclable product - Plug & Play:
Easy and fast on-site installation with automatic radio activation (no programming required) - Performance driven design:
Range up to several km (LoRaWAN) or up to several hundred meters (wireless MBus) depending on environment - Integrated monitoring of connectivity and reconnecting mechanism (LoRaWAN):
Robust operation with automatic repair options, e.g. due to gateway failures
Applications
- Residential consumption monitoring of water consumption within an entire building
Options
- Only LoRaWAN transmission mode
- Only Wireless M-Bus transmission mode
