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.

CMe3000 is a cost-effective M-Bus Gateway for Fixed Network which acts as a communication tunnel for M-Bus meters and enables them to communicate with a receiving system. 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. It is also compatible with all other meters using the M-Bus protocol. Through its integrated web interface, CMe3000 can be configured and updated remotely without having to visit its installation site.
