Cellular modem designed specifically for the remote automatic meter reading of Landis+Gyr^® E350, E450, E550 (type Zxx 3xx and Zxx 4xx) electricity meters. The device can be ordered with various cellular module types. In collaboration to provide state-of-the-art cellular modems for its customers in Europe, WM Systems was selected as one of the OEM suppliers of Landis+Gyr.

The product’s case was designed to fit under the enclosure of the meter and it connects through an RJ45 data connector. As part of an AMR/AMI solution, the modem provides a stable, transparent connection to the meter through which the HES can pull consumption data from the meter.

The modem can send data by CSData call (2G) also. This is an ideal solution for remote readout of registers and consumption data of the connected electricity meters.

The modem is fully configurable by our powerful and easy-to-use WM-E Term^® software.
