Abstract
Wet stream is extracted isokinetically through a steam sampling nozzle and is directed, preferably vertically, through a moisture separating and divider unit (24) having a center tube (84) coaxially disposed in a substantially cylindrical shell (20), and a helical swirling device (98) coaxially located within the tube, which imparts centrifugal motion to the wet steam. As the steam passes through the helical device, the separated moisture droplets are drawn off from the vapor through holes (92, 94) in the periphery of the tube and fall to a liquid accumulator volume (26) in the shell. The extracted vapor is passed out of the shell to a measurement station including an orifice plate or venturi. Sensors (48, 50) are provided in the shell accumulator volume, to measure directly or indirectly, the mass of water extracted from the moisture separator. Similarly, the orifice plate and associated sensors (36, 38), measure the mass of vapor in the steam from which the liquid was extracted. Preferably, the orifice plate has differential pressure and absolute pressure sensors associated therewith for this purpose. Once the mass of liquid extracted from a known mass of total liquid and vapor is measured, the quality of the wet steam as sampled, is directly recorded indicated on a memory device (66).
