QMBM3L

Brooks Instrument Quantim QMB Coriolis Mass Flow Meter

About this part

QMBM3L is a Brooks Instrument Quantim QMB-series Coriolis mass flow meter. QMBM designates a meter with no integral control valve, as distinct from the QMBC controller, and the size digit 3 designates a larger sensor than the size-2 QMB. Quantim Coriolis measurement is largely independent of fluid type and process conditions. The exact flow range, service, seals, fittings, and electrical interface of this configured meter are encoded in the full model string (observed as QMBM3L 1A3A 1B3A 1BB1H1A1AA) 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.

QMBM vs QMBCQMBM is a meter with no valve; QMBC is a controller with an integral control valve.
Size digitThe digit after QMBM/QMBC (2, 3, or 4) sets the sensor flow capacity; 2 is the smallest.
Option stringThe characters after the size digit encode service, seal, fitting, and electrical/communication selections and are decoded from the Brooks ordering guide or the device label.
Generation noteThe newer Quantim QMC series is documented as compatible in fit, form, and function with second-generation QMB models.
