It can cover any eventuality from a simple check meter on the mains incomer to hundreds of sub meters sending data back to a BMS or PC.
In addition to single and 3 phase min & max voltage and current, the meter provides “management information”:-
- kVA (apparent power, instant, max, min and total)
- kW real power, instant, max, min and total
- Power Factor
