    • A monitoring system is presented. The monitoring system may include a first chemical vessel containing a first chemical mixture and a second chemical vessel containing a second chemical mixture. The monitoring system may further include a sensor configured to selectively receive a first sample flow of the first chemical mixture from the first chemical vessel and a second sample flow of the second chemical mixture from the second chemical vessel. The sensor may be configured to measure a first sample attribute value of the first sample flow and a second sample attribute value of the second sample flow. By multiplexing multiple sample flows through a sensor, the monitoring system may monitor attributes of multiple chemical mixtures without requiring separate sensors for each chemical mixture monitored by the system.In an embodiment, the monitoring system is preferably configured to control an attribute of a chemical mixture. In such a case, the monitoring system may further include a control system configured to receive the first sample attribute value and the second sample attribute value from the sensor. The control system is further preferably configured to input the first sample attribute value into a first attribute control algorithm to calculate a first attribute control output. The first chemical mixture includes a first bulk attribute value, and the control system is preferably configured to direct the adjusting of the first bulk attribute value.
    • 介绍了监控系统。 监测系统可以包括含有第一化学混合物的第一化学容器和含有第二化学混合物的第二化学容器。 监测系统还可以包括被配置为选择性地接收来自第一化学容器的第一化学混合物的第一样品流和来自第二化学容器的第二化学混合物的第二样品流的传感器。 传感器可以被配置为测量第一样本流的第一样本属性值和第二样本流的第二样本属性值。 通过将多个样品流复合通过传感器,监测系统可以监测多种化学混合物的属性,而不需要由系统监测的每种化学混合物的单独的传感器。 在一个实施例中,监控系统优选地被配置为控制化学混合物的属性。 在这种情况下,监视系统还可以包括被配置为从传感器接收第一样本属性值和第二样本属性值的控制系统。 控制系统还优选地被配置为将第一样本属性值输入到第一属性控制算法中以计算第一属性控制输出。 第一化学混合物包括第一批量属性值,并且控制系统优选地被配置为引导第一批量属性值的调整。
