Model 555 handles flow proportional control, residual control, compound loop control with lag times, and de-chlorination with sulfur dioxide. Designed for water and wastewater applications, the 1/4 DIN controller has a NEMA 4X-rated front panel for protection from water and corrosion. When performing compound loop flow pacing control, the unit displays flow rate and residual chlorine simultaneously.
