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 in structured meter data reports to a receiving system, or to enable a meter to communicate by M-Bus/Wireless M-Bus.

CMeX20 is an external meter connectivity module used to collect meter data from an ABB B21/B23/B24 electricity meter and deliver it to a receiving system by M-Bus. The MCM communicates with the ABB meter through IR and will initiate collection of data immediately after start-up. CMeX20 has a modular design, which makes it easy to extend an existing installation if needs are changing.
