In 21 days my reading went from 18098 to 19970 which basically means i was using 90 kwh per day
What date did you move in? Do you know for certain when the meter was actually read?
What day did you take the picture of the meter?
There is definitely a problem reading this because you cannot tell for certain the second digit.
Since the middle dial is on 4 the second dial should be 4/10th past either 9 or 0. In the picture the second dial is on or very near 0 so how would you know if it should be read as a zero or a 9? It is ambiguous.
In reading these style meters, you would look to the right to make a determination. In this case, the second digit is a zero because the third dial is past its zero.
