Hope you will find it interesting to know.
I contacted a small company with great idea.
They developed a small sensor, based on heating, cooling and temp. measuring (all in one sensor) that can calculate in two phase flow (Steam and water or gas - liquid systems like air conditioning system) the quality of steam or the precentage of liquid in the gas flow. The instrument gives an on line measuring which is fed into the PLC / DCS for dataloging or control.
The instrument is already in use by aircrafts air conditioning system and the company is now checking the option to convert it to steam - water aplications. If any of you think it interesting please leave a note to Dr. Gadi Golan of ATCT ( at: Gady@atct.co.il
This instrument is not yet at the company site but I hope it get there soon.
 
That can be great but how are you calculating water content by temperatre? The temperature of unsaturated steam need not be lessthan that of saturated steam.

 
sounds like a dew point determination after the method used by Land Instruments
