Oh well, I'll run the errand tomorrow...
 
As a start, go read about the gas laws and partial pressure and how humidity is 
calculated from
partial pressure...
 
In order to understand how Galantini can ESTIMATE the liquid water content of 
the steam, you need to
think several steps ahead as in chess, or in a complex mathematical derivation 
that involves many
steps and applying theorems at each step in order to derive the final desired 
answer.  Its not a
direct measurement as I've said numerous times.
 
The behavior and properties of gases are very different from liquids, and are 
dictated by mass or
mole fraction, not concentrations.
"Gases dissolve, diffuse, and react according to their partial pressures, and 
not according to their
concentrations in gas mixtures or liquids."
 
If you vaporized so many grams of liquid water into a cubic meter box with NO 
other molecules
present, you'd end up with a specific temperature and pressure, and that could 
also be communicated
as a mixing ratio.  For atmospheric science where we ARE dealing with air, then 
the mixing ratio is
the mass of water (if you condense the water vapor) to the mass of dry air.  
However, you do NOT
need other molecules in order to measure humidity.
 
Another quote which might help...
"This general property of gasses is also true of chemical reactions of gasses 
in biology. 
 For example, the necessary amount of oxygen for human respiration, and the 
amount
 that is toxic, [my emphasis] *** is set by the partial pressure of oxygen 
alone ***.  This 
 is true across a ***very wide range of different concentrations*** of oxygen 
present 
 in various inhaled breathing gases, or dissolved in blood."

So you're getting hung up on the denominator thinking that there has to be some 
entity or volume of
some other molecule(s) when in fact, it might as well say, "cubic meter of 
empty space".

STOP THINKING ABOUT VOLUME!  Yes, you're right in that the extreme volume 
change complicates the
measurements, and thats why I and others including Krivit, are focused on MASS. 
 Think in terms of
mass.  That eliminates the complication of the 1700:1 change in volume that you 
are stuck on.  
 
If you condense all the gaseous water molecules (i.e., the water vapor) and you 
then measure the
mass of the CONDENSED LIQUID water (that USED TO BE VAPOR), that is what the 
meter is measuring in
grams of water (molecules) per m^3! 


You just told me to stop thinking about volume, and then you give me a quantity 
with units of mass
per unit volume. You are thinking about volume, and that's why I am. If that 
device did as you say,
where do you get the m^3 to calculate the total mass of the vapor?

But no. That device is not measuring the mass of condensed liquid. It's 
measuring capacitance, which
is affected by the wetness of a dielectric, which corresponds in some known, 
predetermined way to
the amount of water vapor in air. There is no known, predetermined 
correspondence between the
wetness of the dielectric and the mass of condensed liquid that used to be 
vapor, or the fraction of
steam in a steam-mist mixture. No matter how many caps you use. Sorry.
