従来の混合流体の濃度計測においては、流体の屈折率が濃度によって変化する ことを利用した光学式の装置を用い、あるいは、手作業による化学分析により行 われていた。 In conventional concentration measurement of mixed fluids, the refractive index of the fluid changes depending on the concentration. This can be done using an optical device that takes advantage of this, or by manual chemical analysis. I was worried.
【０００３】0003
従来の流体に光を照射しそのときの屈折率により流体濃度を求める光学式の装 置を用いた測定においては、流体が着色料などにより着色されていた場合は流体 が光を透過しないため、屈折率の計測が不可能となったり、混合流体の種類によ っては流体濃度と屈折率の関係が一対一の対応ではないため（濃度が大きく異な るにもかかわらず屈折率が同一である場合がある）、流体濃度の特定ができない などの課題があった。また、手作業による化学分析については、分析に長時間を 要し、常時流体濃度を計測し監視を要する化学装置等の場合には適当ではなかっ た。 A conventional optical device that irradiates light onto a fluid and determines the fluid concentration based on the refractive index at that time. When measuring using a liquid, if the fluid is colored with a colorant, does not transmit light, making it impossible to measure the refractive index, or depending on the type of mixed fluid. This is because the relationship between fluid concentration and refractive index is not a one-to-one correspondence (if the concentration is greatly different), The refractive index may be the same even though the fluid concentration is not determined. There were issues such as: In addition, manual chemical analysis requires a long time. Therefore, it is not suitable for chemical equipment that requires constant measurement and monitoring of fluid concentration. Ta.
