The C100A Variable Speed Controller from Fluid Metering (Syosset, NY) provides a control interface for the company’s Variable Speed Pumps. The C100A features both manual speed adjustment using a front-panelmounted rotary dial, as well as electronic speed control via a 4-20 mA signal from an external source.
The unit is used for controlling the Chloritrol® Valveless Hypochlorite Injection System and the CTS Chemical Treatment System, both of which provide maintenance-free fluid control in the water and waste-water treatment industries. The controller retains settings and resumes operation following a power interruption or failure. The electronics are housed in a NEMA 4/12 enclosure suitable for wall mounting.
