The first technique you suggested would spread out the test for too long of a time(hour). It would be difficult to get a good snap shot of the instantaneous performance. The technique used by Mats is the best that can be had under these circumstances. I do not feel that he had significant errors in his determination of the flow.
The input flow meter leaves doubt also. The leakage is unknown and level of water is not ensured to be topped off. There is evidence that the vapor has an existence above the water that varies.

I wrote: If you collected the condensate for an hour while running it through a precision flowmeter you might get a better handle on this, and a more meaningful answer. You have to leave it in a steady state. But I would not actually do that. That's kind of nutty. Way too complicated. I would put the precision flowmeter between the pump and the reactor. It measures only cold water going in. Then the only inaccuracy is from the water leaking out of the top of the reactor. I don't think there is much of that. - Jed
