The Liberty 500 smart meter is a part of the smart metering system. It is a new generation, three-phase, smart electricity meter with communications capability, including DLMS / COSEM. It is equipped with a bi-directional communication unit with provision for a range of communication technologies, including RF or cellular (NB-IoT / GPRS) devices that allow it to interact with the head end system (HES) for data collection and configuration with adequate security.

It covers state-of-the-art smart functionality, coupled with revenue protection capabilities, making it the ideal solution for smart metering applications.

A built-in connect-disconnect switch and intelligent firmware platform in the Liberty 500 can deliver smart metering use cases of an energy supplier.

It provides account balance and consumption information in monetary terms, without any dependency on the WAN communication network, which helps consumers monitor and budget their energy consumption.

Application
• Residential metering
• Commercial metering (large and small)


Benefits
• Easy integration with head-end system through bi-directional comms and interoperable protocol
• Periodic remote data availability for utility reconciliation and monitoring
• Improved reading efficiency and elimination of billing errors through smart functionality
• On-demand data collection to serve critical use cases like vigilance
• No site visits to disconnect/reconnect consumer load point
• Enables efficient field operations to quickly restore faults by providing reliable, timely node-specific power interruption information
• Reduced cost of ownership
• Eliminates the cost of manual reading
• Designed to serve long life in the field
• Peak and off-peak management
