ratio ...to(关于仪控)? E--->C Controls the maximum amount of A product that can be taken from the column based on the required reflux ratio (defined as top reflux divided by the A product rate {weight/weight}). FFC-30-27 is the reflux ratio controller that sends a signal to FY-33-01. The normal setpoint for FFC-30-27 is 5 kg/kg. FFC-30-27 ratios the reflux flow to its setpoint and then sends this SP to FY-33-01A. FY-33-01 selects the smaller of either the allowed A product rate from FFC-30-27 or the manually input A product rate from FK-33-01. 根据所需的回流比[定义为塔顶回流量除以A产品流量(重量/重量)],调节可从塔抽出的最大A产品量。FFC-30-27为 回流比控制器 ,它向FY-33-01发送信号。FFC-30-27的正常设定值为5千克/千克。FFC-30-27?????,然后再将此设定值发送至FY-33-01A。FY-33-01选择由FFC-30-27给出的允许A产品抽出量或从FK-33-01手工输入的A产品抽出量两者中较小的。(问题:ratio此处如何理解?)
