The Wallace & Tiernan® SFC PC process control system unit is specifically designed for automatic control of disinfection, de-chlorination and chemical feed in water conditioning or industrial process applications.
Thanks to the fuzzy logic technology, compound loop control with flow rate and access to the controlled process variable (e.g. chlorine) results in significantly improved control. The SFC PC system saves its reactions to control deviations permanently and uses this data as a basis for future control, allowing the control variables to be balanced optimally with the flow and the control parameters.
Typically used as a setpoint controller, the SFC PC system provides accurate control of gas feed equipment, as well as chemical metering pumps.
