Product status
The SFC series of analysers and controllers has been discontinued and is no longer available for sale. Limited service and spare parts support will be provided until January 22, 2028.

Overview
The Wallace & Tiernan® SFC PC process control system is designed for automatic control of disinfection, de-chlorination and chemical feed in water treatment and industrial process applications. Using fuzzy logic and compound loop control with flow rate, the SFC PC improves regulation of the controlled process variable (for example, chlorine). The controller records responses to control deviations and applies that data to optimize future control actions. The unit is commonly used as a setpoint controller for gas feed equipment and chemical metering pumps.
