    • PROBLEM TO BE SOLVED: To solve the problem wherein the maintenance control of a ratio of ice particles and water, that is, the concentration of an ice slurry is extremely important in ice particle blast processing for projecting the ice slurry on an article to be processed and the amount of ice particles passing through a transparent conduit is measured heretofore from the outside of the transparent conduit by a light quantity judging sensor but dewing is immediately caused on the wall of the transparent conduit at the normal temperature.
      SOLUTION: A pair of through-holes 2 is provided at the transversal opposed position of the pipe wall 9 of the ice slurry conduit 1 through which the ice slurry 8 passes and the leading end parts 4 of optical fibers 3 is embedded in the through-holes 2 while the other ends of the optical fibers 3 are connected to a light quantity judging unit 6. The concentration of the ice slurry 8 is measured on the basis of the light quantity data brought about by the optical fibers 3 in the light quantity judging unit 6.
