To provide a particle measuring device capable of accurately measuring a physical quantity of sample particles in slurry.SOLUTION: A particle measuring device includes: a first vessel for housing slurry; a second vessel for housing liquid for dilution; a third vessel for housing a diluted solution obtained by diluting the slurry with the liquid for dilution; and a circulation pipe for circulating the slurry in the first vessel at the outside of the first vessel. A first pipe for supplying at least the slurry into the third vessel is connected to the circulation pipe by using a first pipe connection member which is a branch joint member, a second pipe for supplying the liquid for dilution in the second vessel into the third vessel via the first pipe is connected to a downstream side of the first pipe connection member of the first pipe by using a second pipe connection member which is a branch joint member, and the first pipe connection member and the second pipe connection member are provided respectively so that a height position of the second pipe connection member is higher than a height position of the first pipe connection member.SELECTED DRAWING: Figure 1 【課題】スラリー中の試料粒子の物理量を正確に測定することができる粒子測定装置を提供する。【解決手段】スラリーを収容する第一容器と、希釈用液を収容する第二容器と、スラリーを希釈用液で希釈した希釈液を収容する第三容器と、第一容器内のスラリーを第一容器の外部で循環させる循環管と、を有し、循環管には、少なくともスラリーを第三容器内へ供給する第一管が、分岐継手部材である第一管接続部材を用いて接続されており、第一管の第一管接続部材よりも下流側には、第二容器内の希釈用液を第一管を介して第三容器内へ供給する第二管が、分岐継手部材である第二管接続部材を用いて接続されており、第一管接続部材および第二管接続部材は、第二管接続部材の高さ位置が第一管接続部材の高さ位置より高くなるように、それぞれ設けられている。【選択図】図１
