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.
It features IR compensation, current limiting circuit, and minimum and maximum speed adjustment, which are all factory preset.
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.
