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. 

CMeX50 - Wireless M-Bus Receiver

CMeX50 is a Wireless M-Bus Receiver which enables a Gateway from Elvaco's CMe Series to communicate with Wireless M-Bus meters. CMeX50 handles up to 800 Wireless M-Bus meters and guarantees safe data transmissions through individual encryption keys. The product is equipped with an IR interface which makes it easy to connect to other CMe/CMeX products without having to use any cables.
