We believe that an electricity meter does not need to have communications to be called smart.
Our Liberty 1E meter makes prepayment user-friendly and convenient, by vending in money terms rather than units of electricity. Real-time consumption information is displayed in plain language, helping consumers to make decisions that will save money. Optional remote keypads enable consumers to enter vend codes and view information, even when the meter is in a hard to reach place.
- Vend codes are in money, not kWh units.
- Keypad on the meter for entering codes means there is no token/card to lose.
- A ‘Friendly Credit’ option means no disconnection during evenings, weekends or public holidays.
- Highly secure, encrypted vending.
