Universality
Designed to work with DLMS and IDIS, and with devices and systems built to IEC 62056 and IEC 61968, using standard data models. Compatibility with a specific project is confirmed on request.
Solutions
Meters, data collection terminals and management software combined into one system for electricity, water and gas.
AMI system
A modular advanced metering infrastructure (AMI) system, built to evolve over the long term. Its design priorities are universality, openness, security, performance, availability and intelligence.
The system consists of a meter data management system (MDMS), prepayment management (PPM), a head-end system (HES), user information management and asset management. Modules can be combined to suit each project's requirements and application.

Smart prepayment
Prepayment built on the AMI system, for electricity, water and gas meters.
Pay
Customers buy credit with a card, at a vending point or through a mobile app.
Token
Credit is delivered as a token generated through a security module.
Manage
The utility manages accounts with prepayment management (PPM), the meter data management system (MDMS) and asset management.
Deliver credit
The head-end system reaches each meter through a concentrator or gateway over LoRaWAN, power line carrier, NB-IoT or cellular networks.
Automatic meter reading
Readings are collected remotely over the network and passed to the head-end system for billing and analysis.
- Wired: power line carrier (PLC) and RS485
- Wireless: GPRS, 3G, 4G, 5G, NB-IoT, LoRaWAN, RF and Bluetooth
- On-site reading with handheld units where no network is available
Multi-utility metering
Electricity, water and gas meters can be read and managed on the same AMI system.
Medium-voltage power line carrier
Communication equipment that carries data over medium-voltage power lines. See the medium-voltage carrier equipment.
