Product Details:

Liberty 370 is an intelligent, three-phase switched electricity meter that provides information of both mains and DG electricity consumption separately, which makes it an ideal sub-metering solution. It uses a unique and innovative technique to detect the supply source, without employing any wiring and additional hardware. It is developed on a highly reliable and secure metering platform which follows the international ISO 27001 standard. Liberty 370 has a dual-mode capability, pay-as-you-go and accounting mode.
