Brooks Instrument Quantim QMB Coriolis Mass Flow Meter
About this part
This is a Brooks Instrument Quantim QMB-series Coriolis mass flow meter. In the Quantim QMB model code, QMBM designates a meter with no integral control valve, as distinct from the QMBC controller, and the size digit 2 designates the smallest QMB sensor. Quantim Coriolis measurement is largely independent of fluid type and process conditions. The archived unit was labeled for a 90 gram/hour full-scale flow; the remaining configured options for service, seals, fittings, and electrical interface are encoded in the full model string and should be confirmed against the Brooks ordering guide or the device label
Configurations vary. Verify the exact unit before choosing a replacement.

Quantim QMB model-code context
The QMB model code identifies function and sensor size in its leading characters; the trailing option characters require the Brooks ordering guide to decode reliably.
