Digital Mass Flow Controller AFC 202 D & Meter AFM 302 D

   The best solutions for high flow from 30slm to 400slm.

FEATURES

  For high flow from 30 slm to 400 slm, the highest performances of the digital P.C.B. combined with elastomeric seals on the Qualiflow AFC 202 D and AFM 302 D:

Full potential of digital technology.

100% compatible with analog AFC202 by using the D 15 pin adapter (P/N Q2001733-09 or Q2001733-10).

Special pressure compensated stainless steel valve for ultra fast flow control.

Accuracy : During calibration,a polynomial curve (fourth degree)calculated from 6 points gives an accuracy of 1% of setpoint if setpoint >30% of F.S.,  0.3% of F.S. if setpoint <30% of F.S.

Less inventory: Up to 10 calibration curves of different gases can be stored into the memory, easily changeable by user. To keep the benefit of accuracy,the maximum factor between the full scales is 3.

Optimized numerical control : The control of gas flow is done by a numerical algorithm assuming a control without overshoot at any setpoint and improving the response time.Each calibration curve is stored with its own regulation parameters.

Communication modes : Analog mode :the MFC is 100% compatible with analog series,with the advantage to communicate via serial RS232C for Maintenance,calibration. RS485 option: permits to control up to 32 MFC 's under MODBUS protocol (RJ11 connector).

Devicenet or PROFIBUS high speed fieldbus.
