Know how much you are paying, reliable and secure

Liberty 150 is an intelligent single-phase prepayment energy meter that provides real-time and historical information on consumption and accounting. It supports a wide range of tariff facilities. The interactive in-home display (IHD) combines convenience with flexibility by enabling key transactions such as token transfer, without the need of directly interacting with the meter. The IHD device has an inbuilt bluetooth functionality that allows it to receive the vend token from a mobile application. This information is later communicated by the IHD to the meter using a wired connection. Liberty 150 is supported by a web-based vending system that is highly secure, flexible and easy to integrate with utility and payment service provider’s systems.
