Reliable, secure, and provides real-time consumption information

Liberty 150 is an intelligent single-phase, pre-payment 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 directly interacting with the meter. The IHD device has an in-built 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 both utility and payment service provider’s systems.
