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.
