ABSTRACT:
Steam quality, namely the mass of steam vapor divided by the total mass of water and steam vapor, is determined by measuring the degree of fluctuation of the differential pressure signal across the orifice of a single sharp-edged orifice plate in the steam carrying pipe. The steam quality is inversely related to this measured degree of differential pressure fluctuation.
