CMe3100

M-Bus Metering Gateway for Fixed Network

CMe3100 is a M-Bus Metering Gateway for fixed network that reads up to 512 meters, compiles meter data in customised reports and delivers it to a receiving system. 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 it’s web interface and supports a wide range of integration protocols, such as ModBus, DLMS, JSON and REST.

Available for 8, 32, 64, 128, 256 and 512 meter capacity.
