Single-phase smart meter withcellular communications

The i-Credit 511 is a single phase two element smart meter to facilitate independent recording of multiple loads resulting in greater tariff flexibility. The modular design accommodates the latest cellular communication technologies and paves the wayfor reliable data transfer making it the ideal solution for smartmetering applications. The meter supports firmware upgrade, allowing metering andcommunications features, functionality to be updated in the field. i-Credit 511 meters are 'fit for purpose' for all contestable metering installations. This enhances flexibility and makes the investment future-proof. The meters can be used for individualdomestic or small commercial applications, offering value for money with reduced Capex and inventory. The i-Credit 511 smartmeter forms part of the Secure's liberty online smart metering solution. Refer liberty online brochure for system details.
