CGc IP Box - Elvaco box-build for Fixed Network

Elvaco's CGc IP Box is made up of our M-Bus Metering Gateway CMe3100, combined with an M-Bus Master from the CMeX10-13S Series, or our CMeX50 Wireless M-Bus Receiver, fully assembled and connected in a protective enclosure at delivery. This turn-key solution is used to read up to 512 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 fixed network. By using the CGc IP Box together with our LTE-router in A-Box, meter data can also be transmitted over the mobile network.
