Meter Connectivity Modules

Elvaco offers meter connectivity modules for heat and electricity meters. These are used with a specific type of meter to collect data and deliver strucutred meter data reports to a receiving system, or to enable a meter to communicate by M-Bus/Wireless M-Bus.

CMi1020w - Integrated MCM for Landis+Gyr E350

CMi1020w is an integrated meter connectivity module which is mounted in a Landis+Gyr E350 electricity meter to collect meter data and deliver it to a receiving system by Wireless M-Bus. The product can be ordered with a default or customized configuration. This makes CMi1020w a perfect option when a high degree of flexibility and an attractive price point is required and wiring is not an option, for example in sub-metering projects.
