Communication Modules

LoRa is a LPWAN (Low Power Wide Area Network) radio technology that enables long range transmission for objects with modest power consumption allowing using a small battery for several years and keeping the things connected. LoRa acts in the free sub-giga Hertz band, mainly 868 MHz(Europe and 915 MHz (North and South America) and allows transmission in the order of 10+ kilometres. The structure of the network provide the existence of at least a LoRa gateway covering a wide area, able to manage thousands end points ( meters ,temperature sensors, humidity sensors , motion sensors etc) collecting data from them and uploading to the cloud.

Over the LoRa physical layer enabling te long range communication , an upper layer was developed to manage the connection between gateways and end nodes. This is the LoRaWAN standard and its elected as interoperability pre-requisites for an end point as for the gateways to be able to operate together even if produced by different manufacturers , that’s the starting point for an integrated IoT network including several types of devices.

B Meters is a member of LoRa Alliance (Association of manufacturers of connected devices using LoRaWAN standards).

The IZAR CENTER by Diehl Metering is an M-Bus level converter is able to do readings of M-Bus meters with very high resolution (up to 1 minute possible) and over vast distances (5 km and more by using repeaters). The reading of IZAR RADIO meters is possible by using the Hydrometer M-Bus Receiver.

Features

• 60, 120 or 250 M-Bus devices connectable to one IZAR CENTER
• Automatic transmission of meter data via internet connection using integrated LAN interface or external analog/GSM/GPRS modem
• Automatic meter identification by searching the M-Bus network
• Fast and standardized up-to-date communication interfaces
• (Remote) reading and configuration via USB, RS232/modem or LAN interface
• Alarm functionality on consumption and on instantaneous values with notification (email, SMS)
• Compact housing with rail-mounting possibility
• M-Bus master and level converter in one device. IZAR CENTER (without memory) can also be used as M-Bus repeater (amplifier)
• Cascadable to connect more devices or to build up larger M-Bus networks
• Also available as pre-configured system with or without modem in IP 65 or IP 66 installation housing

Principle of Operation

The IZAR CENTER is sending out a request to the connected meters. This action could be initiated manually by the user or automatically by the IZAR CENTER. For automatic reading an IZAR CENTER with memory is required to program general or meter individual reading intervals. The meter is responding to that request by giving its values to the IZAR CENTER. The meter data is stored in an inbuilt memory and can be transmitted automatically to a meter reading software (e.g. IZAR@NET Software).

Elvaco integrated meter modules for heat meters, mounted inside the meter deliver meter data to a receiving server via a LoRaWAN network.The product has a long communication range and is easily fitted inside an already deployed meter. The CMi meter module offers a cost effective solution with lesser demand for bandwidth.

Configuration via mobile phone and NFC communication before despatch or on site.
