This patent describes a steam quality apparatus which measures and monitors the quality of steam flowing in a steam pipe. The apparatus consists of: a test cell connected in line with the steam pipe in a manner so that the stream flows through the test cell, capacitance sensing means contained within the test cell for providing a capacitance output corresponding to the capacitance of the steam, temperature sensing means for sensing the temperature of the steam and providing a temperature signal representative thereof, density determining means connected to the capacitance sensing means and to the temperature sensing means for monitoring the density of the steam flowing through the test cell, and means connected to the density determining means and to the temperature sensing means for deriving the steam quality in accordance with the steam density and the temperature signal and providing a steam quality output related thereto.
