1350GAM3BBNG1AAA is a configured Brooks Instrument Sho-Rate 1350G glass tube variable-area flowmeter. Official Brooks 1350G/1355G documentation identifies the 1350G as a 65 mm Sho-Rate flow indicator, and the model-code table decodes this configuration as a Revision G unit with 316 stainless steel end blocks, R-6-65-B G tube, stainless steel float with custom decal scale, Viton packing and O-rings, 316 stainless steel 1/4 in NPT threaded end fittings with locknuts, NRS #6 316 stainless steel valve, inlet/back-back valve orientation, no alarms, no additional listed option, and no listed certification option. Exact scale markings, fluid, and calibrated range should still be verified from the physical unit label and scale
Configurations vary. Verify the exact unit before choosing a replacement.

Installation
Mounting orientation
Brooks installation documentation describes the Sho-Rate flowmeter as a vertically mounted variable-area meter with bottom-to-top flow
Configuration
Configured-unit rule
Tube, float, scale, process fluid, operating range, valve, seals, connections, options, and calibration context are model-code and unit-label specific
Observed variants
Stored auction identity context
Stored Sonisys auction records identify this exact configured code as a Brooks Instrument Sho-Rate flow meter and include a 200 psig at 250 F listing context
