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. 

CMi-Box - M-Bus Metering Gateway for Mobile Network

This CMi-Box is made up of a Meter Connectivity Module and a Wireless M-Bus Receiver, mounted and connected in a protective enclosure. The CMi-Box reads Wireless M-Bus meters (alternatives for wired M-Bus meters are also available), compiles meter data in customized reports and delivers it to a receiving system by a set time schedule and integration protocol via the mobile network. The product is configured and updated through text messages or HTTP, which means that settings can easily be changed without having to visit the installation site.
