Can 2 Kilowatt meters be connected in parallel without affecting the performance of either, reason for this scenario is for 1 meter to upload data to a computer, whilst the other meter gives a visual indicator of the load.Thanking everyone in advance for their replies.

The load would split between the two, and probably not equally even if they are the same type, due to manufacturing tolerances.
 
It may be possible to connect them in series.

A far better option would to use a current transformer ( CT )to measure current and an interface module to convert the CT analogue signal into a digital signal to suit the computors needs.

If the supply voltage is very variable then a voltage sensor can be added and the computor does the V A calculation.
