Energy Meters



Krishnaa Energy has been in R&D for a long time investing money and time to develop our own energy meters and today we offer more than 30 types of energy meters used for different industries in the electrical side. This division was basically created keeping in mind the various problems faced using other company’s energy meters and that the product should be a class in kind product. We have also integrated our Power Line Communication plug in card as a add on for customers who wishes to do power analysis and automation of their premises. The various meters we manufacture are:
