Brooks Instrument Sho-Rate 1350G Variable Area Flowmeter
About this part
1350GAL3BBFV1AAA is a configured Brooks Instrument Sho-Rate 1350G glass-tube variable-area flowmeter. Official Brooks 1350G/1355G documentation identifies the family as low-flow glass-tube rotameters for gas and liquid service, and the published model-code table supports the configured-code context for this unit. Tube, float, fitting, seal, valve, alarm, option, certification, scale, and calibration details should still be verified from the physical unit label and calibration record
Configurations vary. Verify the exact unit before choosing a replacement.

Specifications
Identification
Device type
Glass-tube variable-area flowmeter / rotameter
Series family
Brooks Sho-Rate 1350G / 1355G low-flow glass-tube variable-area flowmeter family
Configured model
1350G configured part number 1350GAL3BBFV1AAA
Configuration
Model-code context
Brooks 1350G model-code documentation maps this configured code to a 1350G meter with 316SS end block, R-6-65-A glass tube, stainless-steel custom-decal scale/float option, Viton tube packing and O-rings, 316SS 1/8 inch NPT threaded fitting with locknut, high-flow 316SS Cartridge III valve, inlet valve/controller orientation, no alarms, no added options, and no certifications
Configured-unit rule
Installed scale, fluid calibration, float, tube, fitting, seals, valve behavior, options, pressure rating, temperature rating, and certifications should be confirmed from the physical label, calibration record, or Brooks build record before interchange or process-use decisions
Flow
Measuring principle
Variable-area flow measurement using a tapered borosilicate glass metering tube and float
Scale context
The configured code uses the Brooks custom direct-read scale / stainless-steel float option; observed listing evidence reports 1.2-12 SLPM air for this exact identifier, but the installed scale and calibration should be verified from the unit label
Performance
Family accuracy and repeatability
Brooks documentation lists 1350G accuracy as +/-5% at reference conditions and repeatability as 0.25% full scale
Ratings
Family pressure and temperature context
Brooks 1350G/1355G documentation lists family pressure/temperature context of 200 psig from 33 F to 250 F / 13.8 bar from 1 C to 121 C, subject to configured options and service conditions
Materials
Family material context
Brooks 1350G/1355G documentation lists borosilicate glass, brass, aluminum, 316 stainless steel, clear and milk-white polycarbonate, and Teflon among family construction materials; this configured code includes 316SS end block/fitting and Viton tube packing/O-rings
Connections
Configured connection
Model-code table context indicates 316SS 1/8 inch NPT threaded fitting with locknut
Controls
Configured valve
Model-code table context indicates a high-flow 316SS Cartridge III valve
Options
Alarm and certification context
Model-code table context indicates no alarm option, no added option package, and no certification option in the configured code
Installation
Mounting context
Brooks installation documentation states that Sho-Rate 1350G/1355G flowmeters should be mounted within 6 degrees of true vertical
Applications
Application domain
Low-flow gas and liquid indication or control service, including purge, laboratory, analytical, and process-support flow applications where the configured materials and calibration match the service
