Brooks Instrument Quantim QMB Coriolis Mass Flow Meter
About this part
This is a Brooks Instrument Quantim QMB-series Coriolis mass flow device with the size-2 (smallest) sensor. In the QMB model code the leading 'QMBM' designates a meter with no integral control valve; the archived listing described the unit as a Coriolis flowmeter and controller, so whether an integral control valve is fitted should be confirmed against the device label. The unit was listed with 1/4-inch process connections. The remaining configured options are encoded in the full model string and should be confirmed against the Brooks ordering guide or the label
Configurations vary. Verify the exact unit before choosing a replacement.
