This paper presents many technology break-throughs achieved for Multi Circuit Meters.  #these include: Significant reduction in the life time cost of the System in the ratio of 5:1. A unique feature of ON/OFF Control is added.  Extremely low 24x7 low power consumption of the system is achieved.  This Technology Revolution by a UK company would help users to save energy for Net Zero. Payback of the investment in the System could be in less than 12 months.  Thereafter, users can save ££££ each year Energy Costs.  This Technology Revolution makes the UK as the world leader for Sub Metering.
