BR6.6B24 is a Brooks Instrument flow-meter archive identifier observed in Sonisys auction records. The stored listings describe Brooks 1-3750C-V and 1-3750-V flow-meter configurations, while official Brooks documentation located for this review covers the MT3750C metal-tube variable-area flowmeter family rather than an official BR6.6B24 exact-part data sheet. Treat family specifications as context only; exact flow scale, service fluid, fittings, materials, valve, electronics, pressure rating, approvals, and calibration should be verified from the physical unit label
Configurations vary. Verify the exact unit before choosing a replacement.
