Liberty Dual Register is an intelligent prepayment meter for the separate measurement of mains and auxiliary (DG) supplies. Liberty is a flexible and secure revenue management system that delivers a bill-less revenue cycle. It provides convenient payment options to the consumer and eliminates all the difficulties associated with a post-paid system.

The Liberty Dual Register meter automatically determines which source of energy is being used, either from the

supply frequency (PLC based) or by a separate digital input. The amount of consumption is deducted automatically, according to the appropriate tariff.

Application

  • Commercial and residential segment

    The Liberty Dual Register system provides:

    Single-point Payment Solution

    The Liberty prepayment system provides secure, reliable and easy-to-use technology for operation on mains and DG tariffs in a single meter. Payments made by consumers for all these services are accounted for in a single system.

    Common Area Maintenance (CAM)

    Common Area Maintenance involves recovering fixed annual maintenance charges (AMC) and other related maintenance costs by builders from individual consumers. The deductions are applied per square foot of space used by individual flat owners. The Liberty prepayment system enables fixed charges to be deducted according to CAM.

    Advanced Online Vending Software

    Besides meters, the Liberty prepayment system also offers an advanced and configurable server-based online vending software for tariff management, asset management, token generation and MIS report generation.

    Freedom Consumer Interface Unit

    An optional consumer interface unit is available for connection with the Liberty meter. This unit acts as a remote display and token entry point, and facilitates an easy understanding of the instantaneous cost-per-hour of energy usage. It also allows consumers to enter credit and access meter information.  It also shows whether the supply is being drawn from the mains or the DG, irrespective of where the Liberty meter is positioned.

    Central Accounting System

    All transactions and definitions are managed through centralised database servers, which generate information from a single point.

    Load Management

    The Liberty Dual Register meter provides true load control and demand side management by disconnecting the load if it exceeds the sanctioned amount. This helps maintain correct transformer loading.

    Disconnection/ Reconnection

    The Liberty Prepayment System allows consumers to effectively monitor their energy consumption pattern and recharge their account in advance, in order to avoid disconnection.

    • Due to a lack of generation capacity, power cuts are a common problem in India. To provide an uninterrupted power supply to consumers, many buildings are equipped with an auxiliary diesel generator by the builder. Both supplies need to be metered, to ensure correct payment for the energy supplied. One solution is to fit separate meters for the mains supply and the  DG supply. This is not ideal, as it requires more space to install. Operational costs are also higher, as two meters have to be read, and the data processed, for each billing cycle.

      Secure’s solution Liberty 1P, is equipped with signal injector technology. Liberty 1P registers both the mains supply and the DG supply. It also supports prepayment functionality, so the consumer pays for energy in advance. This is of benefit to both the builder and the consumer. For the builder, there is no need to buy and maintain an additional meter. The consumer gains assistance with budgeting and pay-as-go convenience. Liberty 1P informs the consumer about supply availability, and can make informed decisions about also reducing the load when using the DG supply.
