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.

CMi2110 - Integrated MCM for Landis+Gyr UH50

CMi2110 is a powerful and versatile meter connectivity module which is mounted inside a Landis+Gyr UH50 heat meter to act as a Gateway for the mobile network. The module is easily installed via text messages, and is thereafter ready to read the meter and deliver customized meter data reports to a receiving system by a selected time schedule and integration protocol via the mobile network.
