To provide a practical slurry concentration measuring device which is not conventionally provided.SOLUTION: There is provided a slurry concentration measuring device which is provided on a wet blast processing device for ejecting with compressed air, slurry 30 being a mixture of liquid 30a and abrasive grains 30b. In a device body 1, a slurry passage part 2 is provided for allowing passage of the slurry 30, a light transmission part 3 for transmitting light is provided on a prescribed position of the slurry passage part 2. In a state of interposing the light transmission part 3 therebetween, on front and rear facing positions of the device body 1, a light radiation part 4 radiating light, and a light reception part 5 receiving the light radiated from the light radiation part 4, are provided respectively. The slurry concentration measuring device further comprises a calculation mechanism for calculating slurry concentration of the slurry 30 by radiating the light from the light radiation part 4 to the slurry 30 passing through the slurry passage part 2, and on the basis of the light reception amount of the light received on the light reception part 5.SELECTED DRAWING: Figure 1 【課題】本発明は、従来に無い実用的なスラリ濃度測定装置を提供することを目的とする。【解決手段】液体30ａと砥粒30ｂとの混合物であるスラリ30を圧縮空気とともに噴射するウエットブラスト処理装置に設けられるスラリ濃度測定装置であって、装置本体１の内部にスラリ30の通過を許容するスラリ通過部２が設けられ、このスラリ通過部２の所定箇所には光を透過する光透過部３が設けられ、この光透過部３を間に挟んで前記装置本体１の表裏対向位置には光を照射する光照射部４と該光照射部４から照射される光を受光する受光部５とが設けられ、前記スラリ通過部２を通過するスラリ30に前記光照射部４から光を照射し当該光を前記受光部５で受光する受光量に基づき該スラリ30のスラリ濃度を算出する算出機構が設けられたものである。【選択図】図１
