Solutions for smart metering and remote control of electricity and water meters. Accurate measurement of consumption for billing, data security and compliance.

Intelligent devices like  smart meters are typical Machine-to-Machine communication devices (M2M). Cellular communications are the de facto solutions for M2M communication. Next generation cellular communication devices that are at the heart of any modern AMI/AMR infrastructure. It’s not surprising most DSOs today use cellular modems or modules in their smart meters.

We offer state-of-the art cellular communication devices for electricity and water metering!




smart electricity meteringSmart metering is crucial not only for billing purposes, but most importantly to gain actionable insight about the demand on the grid in order to be able to balance it better with supply. Smart metering begins with communication devices that collect and send data to a central management planform. Today, cellular IoT technologies such as NB-IoT and Cat-M1 allow massive smart metering systems to operate reliably and cost efficiently.

We offer cellular IoT communication devices for smart metering solutions. Modems and routers allow for Automated Meter Reading (AMR) of electricity and water meters!

You can also build infrastructure – by combining with our data concentrators, routers –  to collect  and send data to the central head-end-system (HES) or a database.

Our modems were specifically designed for the electricity meters of large manufacturers (Elster®, Honeywell®, Itrón®, Landis+Gyr® and EMH®). These modems are at the heart of AMI (Advanced Metering Infrastructure) of public utility companies.

The modems connect to the meters, read the consumption data (through RS232/RS485), and send them to the data center via cellular networks, while providing remote access and monitoring features for the head-end systems. Features include transparent push data sending, pull on-demand requests, scheduled readouts, and  meter data downloads, and more.

Some of our modems support the multi-meter connection, allowing to connect multiple meters to one modem. The meters are connected via RS485 and the modem sends the data from a single “master” meter. This is a cost-effective solution when implementing an automated energy metering system.

smart water meteringOne of the main challenges water companies face today is what the industry calls Non-Revenue Water, the quantity of water lost due leakage and theft.

The right information at the right time enables the right decisions. Digitalisation and intelligent use of data make it possible to improve operational efficiency as never before.

We solve the limitations of network construction in legacy two-hop networks LoRa or RF.   These traditional technologies operate on unlicensed spectrum, which may cause channel interference among different applications, such as water, electricity metering or public street lighting.

NB-IoT offers deep coverage and massive connections with low power consumption. It is an ideal network communications technology for the smart water solution.

Our Device Manager software adds true value to any smart water metering solution. Using a Windows-based remote device management platform, you have continuous access to your devices.

We also provide a simple Grafana framework for the visualization of water metering data.
