Liberty 100 family
We believe that a smart meter is installed not just to provide an energy supplier with more information to put in their customers’ bills or statements. It is also there to show the customer exactly how much energy they are consuming throughout the day. This real-time information helps the customer see where they can reduce consumption, thereby saving money and reducing carbon emissions.
Secure Meters is proud to present the Liberty 100 family of smart electricity meters. These are designed to meet the United Kingdom Smart Metering Equipment Technical Specification (SMETS) and give customers and energy suppliers a full range of both Smart Prepayment and Smart Credit features. Together with an easy-to-use in-home display (Pipit 500) or other smart in-home devices, these meters give energy suppliers the information they, need as well as allowing customers to take control of their energy consumption.
- Smart Electricity Meter with communication hub
- Modular design – the communications hub can be replaced without removing the meter.
- Can be part of a single-fuel (electricity only) or a dual-fuel (electricity + gas) installation.
- Simple installation and registration process
- Operates in either Smart Credit or Smart Prepayment mode.
- Operating modes can be remotely activated and the meter can be remotely reprogrammed.
- Additional switched circuit for Economy-7 and Economy-10 (Night Storage/Water Heating) installations (Liberty 110)
