Stage: PROBLEM TO BE SOLVED: To accurately measure the characteristics of muddy water in real time regardless of its properties.SOLUTION: A muddy water characteristics measuring device 200 that measures characteristics of muddy water comprises flow rate adjustment means (liquid supply pump 61, valve 642, flow rate control unit 71b) that adjusts the flow rate of muddy water flowing through a measurement pipe section 641 to a predetermined set flow rate, differential pressure measuring means (first pressure gauge 644, second pressure gauge 645, differential pressure calculation unit 71a) for measuring the differential pressure of muddy water flowing through the measurement pipe section 641, first calculation means (yield value calculation unit 71c) that calculates the shear rate and shear stress of muddy water flowing through the measurement pipe section 641, and second calculation means (yield value calculation unit 71c) that calculates the yield value of muddy water flowing through the measurement pipe section 641. There are multiple set flow rates. The first calculation means calculates the shear rate and shear stress corresponding to each of the plurality of set flow rates based on the measurement results of the differential pressure measuring means. The second calculation means calculates the yield value based on the calculation result of the first calculation means.SELECTED DRAWING: Figure 3 (Grant)
