They did change the measuring method and Im surprised, this are very
clever changes:
1) The output hose has thermal isolation now. Also the hose is shorter.
So the hose cannot loose (much) thermal energy.
Therefore it is possible to measure the /total/ energy at the end of the
hose.
2) The temperature inside the e-cat is remarkably higher than 100
centigrade. Therefore we can totally neglect whats going on inside the
ecat. Its perfectly satisfying to measure the output at the end of the
hose and the input at the pump.
We can also conclude from this that the pressure inside the e-cat must
be above air pressure, but we dont need to know the pressure inside,
because finally at the end of the hose the steam and water will be at
air pressure.
3) They are measuring the output flow at the end of the hose. Therefore
we know the difference between input water flow&temperature and output
water flow&temperature and from this we can calculate the amount of
(almost) dry steam.
So we know all input conditions and we know all output condition and
therefore we can calculate the energy.
I think all these modifications are very clever and satisfying.
