Wallace and Tiernan® 系统 SFC SC 控制器/分析仪

SFC SC 系统适用于水处理中使用的按流量比例控制的化学品计量,以及类似于工业流程的应用。

The SFC SC system is used for flow proportional controlled dosing of chemicals used in water treatment and for similar industrial process applications. It can control automatic v-notch positioners in gas feed systems, such as the V10k™ and V2000™ systems, or automatic stroke length positioners and variable speed drives in dosing pump systems. The SFC SC system is available either as standalone wall-mounted unit, equipment-mounted, or as a panel-mountable unit for installation in a control enclosure.
