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. 

CMc GPRS Box - Elvaco box-build for Mobile Network

Elvaco's CMc GPRS Box consists of our M-Bus Metering Gateway CMe2100 and an M-Bus Master from the CMeX10-13S Series, fully assembled and connected in a protective enclosure at delivery. This box-build solution is used to read up to 128 M-Bus meters, compile meter data in customized reports and deliver it to a receiving system by a set time schedule and integration protocol via the mobile network. Our Wireless M-Bus Receiver CMeX50, which enables communication with up to 128 Wireless M-Bus meters is available as an add-on option.
