Those variables can be derived (if you know other variables), but they're not what is being measured. Ofc, even the mass flow measurement is not direct, it is derived from heat loss.

Wrong on so many levels. To start with, pressure, volume, and temperature are interrelated. (that explanation tends to be overly technical, Google "PVT" for others). If you change any of those variables, something else has to change. If you increase the pressure (ram air) and the temperature stays the same (there will be a slight increase of temp anytime you compress a gas, but not important for this discussion), the volume has to decrease. When the volume decreases, the density goes up.

The raison d'être of ram air is to increase pressure which in turn increases density which means more O2 molecules per unit of volume.
