  • System and method for continuous measurement of pulp consistency in a blowline of a continuous pulp digester
    Patent number: 4963229
    Abstract: A system and method to continuously determine the pulp consistency in the discharge blowline (112) of a continuous pulp digester (100) having a gamma gauge (116) disposed adjacent to the blowline (112) for continuous measurement of the intensity of gamma radiation attenuated by the pulp slurry passing through the blowline (112), a density gauge (118) disposed adjacent to a cold blow liquor line (102) for continuous measurement of the density of the cold blow liquor in the cold blow line (102) independent of variations in the gamma radiation mass-attenuation coefficient of the cold blow liquor in the cold blow liquor line (102), a gamma gauge (120) disposed adjacent to the cold blow liquor line (102) for measuring the intensity of gamma radiation attenuated by the cold blow liquor passing through the cold blow liquor line (102) and a computer (122) for receiving signals output from the first gamma gauge (116), the density gauge (118) and the second gamma gauge (120) indicative of intensity of gamma radiation a
