Infrastructure

Elvaco's Infrastructure segment is made up of products that enable collection, processing and delivery of meter data. Our M-Bus Gateways are used to read meters and deliver meter data in a suitable format to a receiving system. M-Bus Masters extends the number of meters a Gateway is able to use and Wireless M-Bus Receivers enables the Gateway to communicate with Wireless M-Bus meters. Elvaco also offers turn-key solutions, which are assembled, connected and ready to start using at delivery.

CMe2100 (gen.3) is an M-Bus Metering Gateway for Mobile Network that reads up to 128 M-Bus meters, compiles meter data into customized reports and delivers it to a receiving system by a set schedule and integration protocol via GPRS. The product is equipped with an IR interface which enables it to communicate with other devices from Elvaco's CMe/CMeX Series as well as ABB electricity meters without using any cables. CMe2100 (gen.3) is further compatible with all other meters that use the M-Bus standard protocol. The product can be configured and updated remotely through text messages or HTTP, which means that settings can easily be changed without having to visit the installation site.
