Brooks Instrument Quantim QMB Coriolis Mass Flow Controller
About this part
QMBC3L1B3A1A1A2AA1X7A1AA is a configured Brooks Instrument Quantim QMB-series Coriolis mass flow controller identifier observed in Sonisys auction records. Official Brooks documentation identifies QMB as a legacy low-flow Coriolis meter/controller series and identifies QMBC as the controller model with an integral control valve. The complete configured suffix was not decoded in an official exact-part build sheet, so fluid, full-scale calibration, wetted materials, seal package, enclosure, approvals, connector, output, and process-connection details should be verified from the physical unit label, calibration record, or Brooks build documentation
Configurations vary. Verify the exact unit before choosing a replacement.

Key Facts
Specifications
| Part identifier | QMBC3L1B3A1A1A2AA1X7A1AA |
| Manufacturer | Brooks Instrument |
| Series family | Brooks Quantim QMB Series low-flow Coriolis mass flow meters and controllers |
| Model role | Brooks QMB documentation identifies QMBC as a Quantim controller with an integral control valve, distinct from QMBM meter variants without a valve |
| Measurement principle | Coriolis mass-flow measurement with fluid density and temperature measurement context in the official QMB-series manual |
| QMBC size-3 family range context | Official QMB-series documentation lists QMBC tube size 3 controller-class liquid maximum flow of 1.00 kg/hr, nominal liquid flow of 0.78 kg/hr, and nominal gas flow of 0.214 kg/hr; exact configured calibration remains nameplate dependent |
| Family accuracy context | Official QMB-series documentation lists standard measurement accuracy context of 0.2% of rate for liquid and 0.5% of rate for gas, with accuracy limited by zero stability at low flows |
| Controller turndown context | Official QMB-series documentation lists controller turndown as 100:1 or down to the minimum measurable flow, whichever flow rate is greater |
| Power context | Official QMB quick-start wiring diagrams show 14-27 Vdc power-source context for the Quantim device; verify wiring and I/O against the physical unit before service |
| Configured-unit rule | Fluid, full-scale range, process connections, wetted materials, seals, enclosure, approvals, electrical interface, valve details, and calibration vary by complete configured code and unit records |
| Official document coverage | The locally hosted Brooks QMB Series installation and operation manual applies to the QMB/Quantim family but does not name or fully decode the exact QMBC3L1B3A1A1A2AA1X7A1AA configured suffix |
