A NEW CONCEPT IN GAS FLOW CONTROL
Here is a SELF-CALIBRATING, GAS-INDEPENDENT, UNFOULABLE GFC ...
Easily REPLACE these MFCs which can foul, lose calibration, and are gas-dependent ...
Electrogrip's GFC-2 flow controller features:
The GFC series enables quick interchange with standard MFCs:
The GFC series is available with
For more information, please request GFC data.
COMPARE WITH Mass Flow Controllers (MFCs), which use an indirect thermal transfer method to estimate gas flow.
MFCs are gas-dependent, position sensitive, exhibit zero drift, are easily contaminated, and are sensitive to upstream pressure variations;
The GFC has few internal components, but uses fundamental principles to determine gas flow in real time;
GFC flow control uses a small cyclic pressure variation in its Flow Sense Volume; this ~0.1% pressure variation yields real-time, absolutely calibrated gas flow with unmeasurably small downstream flow and pressure variations.
RESULT: Gas flow rate is dynamically controlled, independent of zero drift, gas type, system fouling, upstream pressure, GFC orientation, etc.
