I don't know any more than what Engineer48 wrote. I don't think there
is any point in speculating at this time.
The only reason I brought it up was because it gives the lie to what
Murray claimed.

what is the point of having all those digitally controlled pumps if
there is no control?

That is certainly what I would expect in an ideal configuration. But,
why would 22 of the pumps be set to full output and 2 to one half
output unless manual control was being used for their settings?
Should they not all be set for automatic control in some manner?
Also, I noticed that each and every one of the pumps pictured were
displaying a steady green light. According to the writer that
indicated that they were pumping accurately according to their
internal program. If controlled separately it would seem likely that
at least one would be off during the picture.
I reviewed the article you suggested and see that it represents the
opinion of the author and not Rossi or IH directly. We need direct
confirmation by Rossi or IH before accepting the proposed diagram. I
am a bit surprised that all 6 of the pumps associated with a single
tiger would feed a common input pipe according to Engineer48. It
would make far more sense for each pump to feed a single component of
the device. In his suggested configuration most of the precision is
wasted and it would appear that less control of the entire tiger is
available due to the parallel operation of all of the heat sources
independent of the variation expected due to material differences.
To further investigate this issue, do you have the model number of the
pumps? Also, Engineer48 makes the statement that the output is at the
top of the pump which leads to the unusual contradiction I discussed
above. Is another pump configuration available that has the fluid
output at the other port? This would make more sense to me. In that
case each section of the tiger would have independent flow control.
Another issue that you may be able to clarify is the temperature
feedback sensor location and reading. Since the output of the steam
is at 102 C or in that vicinity, the actual tiger sections must
operate above that level. To have any control of consequence each
heat source needs to be operating at a temperature that is several
degrees higher. At least one earlier Rossi demonstration showed the
source temperature of 130 C or in that vicinity. That amount of
temperature increase would certainly be adequate for control sensing.
I noticed that Engineer48 left that reading blank on his diagram, do
you have information to fill it in? I am sure Rossi would know the
engineered value.
