专利汇可以提供Multiparameter process solution analyzer-controller专利检索，专利查询，专利分析的服务。并且A multiparameter analysis system for the continuous on-stream real-time measurement, surveillance and correction of a process solution. Electrometric methods are employed to measure conductivity and ion concentration of the process solution. An accurate measurement of actual ion concentration is made by continuous automatic titration of a sample of the process solution. This electrometric analysis produces a signal reflecting the results of said analysis that is fed to controller-analyzer means which generate error signals when said solution deviates from a preselected state, which error signal controls means to automatically restore the process solution to the preselected state. The electrometric analysis means are protected by an automatically self-cleaning filter, the cleaning cycle of which is controlled in response to sensed system dynamics. While this system has particular utility in the analysis and control of nitrite in the surface conversion coating of ferriferous metallic objects, it possesses broad spectrum analytical capability including control of pollutants discharged into surface waters and for the quality control of surface waters.，下面是Multiparameter process solution analyzer-controller专利的具体信息内容。
