NyTeknik maintains that the liquid mass is at most 10% (steam quality at least 90%) and because of this there is no significant error in measuring the heat output using the steam.
That's based on a steam expert, apparently, who has probably never seen, in his entire career, a "boiler" that is designed so that feed water spills out. So he doesn't consider the possibility. He only thinks of "tiny droplets" that will normally form from the boiling process. That's where "10%%" comes from. But if you spill input water into the outlet opening through which substantial steam is flowing, you will get *very* wet steam. It will be atomized there, blown into smithereens by the steam flow through that small opening.
