three element smart meter withcellular communications

Sprint 231 is a single-phase three-element smart meter with three separate measuring elements for independent recording of multiple loads, such as general domestic, solar, hot water or electricvehicle charging (EV). Its field-replaceable communications module enhances flexibility, and makes the utility's investment future-proof. The meter supports firmware upgrade, allowing metering andcommunications features, functionality to be updated in the field. Sprint 231 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 Sprint 231 smartmeter forms part of the Secure's liberty online smart metering solution. Refer liberty online brochure for system details
