Flow Proportional Control

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.
