| FIC-1001-M Constant Volume Flow Controller with Indication |
| |
 |
|
| The FIC-1001-M is a dedicated analog electronic three-mode controller with transducers, square root extractor, and scaling circuit with process indication, housed in a compact enclosure. The FIC-1001-M is designed to maintain a constant flow through a fan or duct section. Unlike other systems that incorporate a standard proportional band, reset (integral), and derivative (P,I,D) control, the FIC-1001-M incorporates inverse derivative with proportional and integral control (P,I,1/D), making the controller very responsive, without hunting and overshooting, as is often seen in standard less precise P,I,D controllers. The measured air volume is independently indicated on a front mounted magnehelic pressure gauge scaled in cubic feet per minute (cfm). |
