PROBLEM TO BE SOLVED: To simply perform measurements and objective determination, without opening a pipe or replacing a collision plate to shorten measuring time, improve efficiency, and reduce cost. SOLUTION: This device for measuring solid particles in a fluid in a pipe 1 is provided with the collision plate 3 with a predetermined area as a collision surface for solid particles, a collision plate mounting seat 2 to fix the collision plate 3 in a channel in the pipe 1, a detecting means 4 for detecting elastic waves generated by the collision of the solid particles against the collision plate 3 fixed to the mounting seat 2, and a measuring means 5 to measure the solid particles in a fluid in the pipe 1 on the basis of the elastic waves detected b the detecting means 4. The time and the intensity and number of the elastic waves detected by the contact of the detecting means 4 with the tip part of the collision plate 3 via a transmitting medium are recorded, and the mass, sizes, number, and density of the solid particles in the fluid in the pipe 1 and their temporal changes are compared with predetermined values and determined. |
