I agree with all that has been posted. But...if you have a temperature control valve involved, the condensate cannot be raised, and a condensate pump will be required.

alexchisholm,
My question concerning the vacuum breaker was brought on by an interesting comment that you made in your first post:
"the tube bundle was largely oversized"
If this is true, your heat exchanger is able to produce the desired temperature rise with much lower...
Alex,
1) Do you have a vacuum breaker on the steam side of the heat exchanger ?
2) Does the condensate drain by gravity after the steam trap, or does it go up ?

Oops, there I go assuming again. Here in this part of the country (Illinois) we only have unnatural steam! I'll be over here....reading only....for the rest of this thread.
Maybe I am missing something here......why in the world would you leave condensate in the steam line instead of removing it as soon as you possibly could!!
As dbevil stated, you can measure the condensate after draining it.
Also, is there no place to measure steam flow at the source while it...
