Liberty 310 is an intelligent three-phase pre-payment energy meter that provides real-time and historical information about consumption and accounting in monetary terms. It supports a wide range of tariff facilities, including automatic calculation and deduction of arrears. The associated in-home display (IHD) has an option for Bluetooth communications, allowing the consumer to transfer vend tokens using a mobile app. Liberty 310 works with a web-based vending system that is highly secure, flexible and easy to integrate with utility and payment service provider’s systems.



  • Liberty 310 is an electricity meter with built-in disconnection relay, suitable for domestic or small commercial premises. The consumer buys electricity in advance, either at a vending office or online. The vend amount is transferred to the meter as a credit amount, through a numeric code, either through a keypad, or via an app. Credit is deducted according to actual consumption and the corresponding tariff charges. When credit is low the meter provides an alarm to the consumer on the in-home display. Under certain conditions the meter automatically disconnects the supply when credit runs out. The consumer can reconnect the supply by purchasing a new vend code and entering it into the meter. This system is very convenient for the consumer and the supplier, as it does not disconnect the supply outside office hours. Additional vending options are available, such as recharging through mobile app, utility website, cash card etc.
