For what it might be worth, my Power Master 2 from Array Solutions has an
option called "Net Power" that does exactly what you want.

Subject: W2 Wattmeter idea

 

I just ordered a W2 wattmeter, haven't received it yet, and I already 
want to change something! 

It displays forward power and SWR. When the SWR is 1:1, then the power 
output of the transmitter is equal to the forward power. But when it is 
greater than 1:1, then the actual power output is the forward power LESS 
the reflected power. 

I would like an option to display this output power, forward less 
reflected. This could probably be done in the firmware, a "SMOP" as 
Wayne likes to say. 

I realize that this does not tell you the power delivered to the 
antenna, for which you would need to know the line loss. But it is still 
a more useful indication than just the forward power.
