New Variable Speed Controller Provides Ideal Control Interface for Variable Speed Pumps
Dec 21 2010 Read 637 Times
US manufacturer Fluid Metering Inc., (FMI) C100A features both manual speed adjustment using a front panel mounted rotary dial, as well as electronic speed control via a 4-20mA signal from an external source (sensor, flow meter, analyzer, process controller.. etc).
The C100A features include IR compensation, current limiting circuit, minimum and maximum speed adjustment, which are all factory preset to best meet specific application parameters. It also incorporates transient voltage protection and an AC fuse.
The C100A is ideal for controlling FMI’s patented Chloritrol® Valveless Hypochlorite Injection System and FMI’s CTS Chemical Treatment System, both of which provide maintenance-free fluid control in the water and wastewater treatment industries. It is especially well suited for these applications which are typically 24/7/365 operations in remote locations. The C100A will retain settings and resume operation following a power interruption or failure without the need for manual restart by an operator.
This versatile unit is also an economical control for FMI’s “QV” and “RHV” Series variable speed process and laboratory pumps.
The electronics are housed in a space-saving NEMA 4/12 enclosure suitable for wall mounting.
