WM-E1S Modem for Honeywell, Elster Meters

UPGRADE THE MODEMS NOT THE SMART METERS!

All around the world mobile operators are shutting down 2G/3G networks in order to give way to 5G. Companies that operate smart meters with 2G/3G connectivity must plan the migration to the latest 4G LTE network which is well-positioned to dominate smart metering communication technologies in the upcoming years. The migration to LTE has many advantages, for example, a shorter readout time due to the high-speed network with low latency.

Utilities have two options for migration: replace the meters or upgrade the modems! The 1st option comes with a high CAPEX, while the 2nd option is a future-proof solution that reduces TCO.  

Our company develops cellular modems that work smoothly and are fully compatible with the different models of electricity meters.

These devices were designed to fit under the terminal cover of the meter and are compliant with all Honeywell / Elster meter standards – optionally with Itron, Landis+Gyr standards. 

Our cellular modems represent a future-proof migration solution to the LTE network with the same functionality, on higher data speed. Configuration and firmware updates can be done remotely, minimizing the need for costly site visits.

Cellular communication modem that has been designed specifically for the automatized remote readout of electricity meters. The device can be ordered with various cellular module types.
You can save money by using our modem because furthermore there is no need for manual readout of the meter systems.

The modem is connectable through its RS232 and RS485 connection, it provides transparent data link to the HES, through the LTE cellular network.

By option, the 2 digital input feature is also available, which can be used for input status monitoring and sabotage detection.

Our modem forms part of the AMI (Advanced Metering Infrastructure) of the utility company.

The device can be used to remotely read the meter’s registers, consumption data of the electricity meters and modify modem parameters. The readout takes place in „PULL” mode, the modem provides transparent communication between the meter and the electricity provider’s HES center.

The modem can be installed under the terminal cover of the meter sealed by the service provider.

The device is configurable with the WM-E Term^®  software and remotely manageable with Device Manager^® software (order option).
