Liberty is the name of our token-less prepayment technology, which is the outcome of more than 20 years at the cutting edge of metering technology. The Liberty family covers a wide range of prepayment applications, from traditional single-phase through to dual-fuel smart metering installations. The flexible nature of Liberty greatly benefits energy suppliers, while the user-friendly features can help consumers reduce their energy costs and achieve reductions in associated CO2 emissions.
Liberty provides a flexible and secure revenue-management solution for suppliers, without the need for tokens, keys or cards. Consumers benefit from innovative features such as programmable load limiting and displays that can help them manage their consumption and reduce their energy costs. The provision of a programmable ‘friendly credit facility’ is of benefit both to suppliers and consumers; disconnection can be deferred if credit expires during unsociable hours. In the simplest systems credit can be transferred to the meter by the consumer, via the keypad. Liberty meters are the basic building blocks for smart meters, whereby credit can be seamlessly transferred by GSM/GPRS signals without any intervention from the consumer.
The Liberty system can be tailored to meet specific supplier requirements, ensuring compliance with legislation and assisting in the reduction of infrastructure costs.
