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. 

CMe3100 - M-Bus Metering Gateway for Fixed Network

CMe3100 is an M-Bus Metering Gateway for Fixed Network that reads up to 256 meters, compiles meter data in customized reports and delivers it to a receiving system by a set schedule and integration protocol via the fixed network. It is compatible with all meters that use the M-Bus standard protocol and Elvaco's CMe/CMeX Series. CMe3100 is easily configured and updated through its web interface and supports a wide range of integration protocols, such as ModBus, DLMS, JSON and REST, which makes it a viable solution for many different types of metering projects. Through the continuous readout feature, meter data can be delivered in real-time, which might for example be used in an automatic control system. CMe3100 is equipped with a flexible licensing scheme, which allows for a cost-effective customization at the purchase point as well as the possibility to later extend the product functionality without changing the hardware.
