Title:
DRYNESS MEASUREMENT DEVICE AND METHOD FOR MEASURING DRYNESS
Document Type and Number:
WIPO Patent Application WO/2018/135130
Kind Code:
A1
Abstract:
A dryness measurement device is provided with: an inspection light emission unit 11 for emitting inspection light having a wavelength that is absorbed by a saturated liquid; a reference light emission unit 113 for emitting first and second reference lights not readily absorbed by the saturated liquid in comparison with the inspection light; an inspection tube 21 for circulating wet steam through the inside thereof, the inspection light and the first and second reference lights passing through the inspection tube 21; a light-receiving unit 12 for receiving the inspection light and the first and second reference lights passed through the inspection tube 21; an absorbance calculation unit 301 for calculating the absorbance of the wet steam with respect to the inspection light and the first and second reference lights on the basis of the inspection light and the first and second reference lights received by the light-receiving unit 12; a correction unit 302 for correcting the absorbance of the wet steam with respect to the inspection light using the absorbance of the wet steam with respect to the first and second reference lights; and a dryness specifying unit 303 for specifying the dryness of the wet steam on the basis of the corrected value of the absorbance of the wet steam with respect to the inspection light.
