MF50XA1BL332BGA identifies a Brooks Instrument Mf50x thermal mass flow controller for industrial gas service. The Mf50x combines a welded thermal flow sensor, integral control valve, and NEMA 4X/IP66 enclosure. Manufacturer documentation defines the MF50 family envelope as 0.003 to 30 slpm N2 full scale; the exact calibrated gas, range, fittings, seal, and analog signals for this configured identifier require its calibration record, order record, or unit label
Configurations vary. Verify the exact unit before choosing a replacement.
