Fastest Settling Time for Turn-on and Turndown
The GFC offers best-in-class settling times for flow controllers by providing settling times below 50ms, both for gas turn-on and gas turndown. An internal GFM (shown in blue) confirms the GFC flow (shown in green). The GFM response lags the GFC response by approximately 0.5 seconds. When a set point changes, this fast settling time results in a transient-free response, no overshoot / undershoot and provides an overall “square wave” flow pattern.
