The M-BUS to LoRaWAN converter is an IOT sensor that reads and transmits energy consumption data from energy meters (gas, electricity, heat, water) for Smart Metering projects. This converter allows a reading of 10 “utility counters” compatible with the European standard M-BUS (“Meter Bus”).
What is the M-BUS standard?
It is a European standard defining the transport and data layers of a communication bus, for reading energy consumption on gas meters, electricity, but more generally also heat consumption meters, water…
The principle is that thanks to 2 wires (as for a telephone line), it is possible to interrogate different connected meters. And so to recover the energy consumption, in Wh (watt-hour), but also coolant temperatures (before and after), the volume of fluid …
The operating principle of M-BUS consists of a Master (here the M-BUS converter to LORA) transmits requests to the counters, the Slaves, by referencing them through secondary addresses encoded in the MBUS-LORA converter.
Like all our LoRa sensors, the 4..20 mA industrial converter has an internal temperature sensor.
Use Cases of the M-BUS to LoRaWAN Converter
- gas meter
- electricity meter
- eat meter
- water meter
Technical Specifications of the M-BUS to LORAWAN Converter
- Up to 10 connected meters!
- Digital Inputs / Safety Inputs: 2
- Digital Outputs: 2
- Built-in temperature sensor
- Direct data transfer or storage and subsequent transmission.
2 Modes of operation
In transparent mode, the converter sends an M-BUS command to a counter and receives the response.
In query mode, the converter generates requests autonomously. The following heat meters are supported in query mode:
- Danfoss Sonometer 500
- Kamstrup Multical 801
- Heat meter «Kamstrup Multical 402»
- Heat meter «Teplouchet-1»
- Heat meter «STE 21 «Berill»
- «WESER Heat Meter»
- LANDIS-GYR Ultraheat T230
