1355GBF3AACA1AAA is a configured Brooks Instrument Sho-Rate 1355G glass tube variable-area flowmeter identifier. Official Brooks 1350G/1355G documentation identifies 1355G as the 150 mm Sho-Rate Size 1-6 flow indicator platform and provides model-code tables that decode this configured code as a 1355G Revision G meter with brass end blocks, an R-6-15-B G tube, glass float with standard 1355 accuracy and custom decal scale context, Buna packing and O-rings, 316 stainless steel 1/8 inch NPT end fittings, valve plug, inlet/back-back connection-orientation context, and no alarm, accessory, or certification option. Exact service range, process fluid, scale markings, and application suitability should be verified from the physical meter label, installed tube, float, and OEM records
Configurations vary. Verify the exact unit before choosing a replacement.

Series family
Brooks Sho-Rate Models 1350G and 1355G
1355G family context
Brooks model-code documentation identifies 1355 as the 150 mm Sho-Rate Size 1-6 flow indicator
Function
Measuring principle
Variable-area flow indication using a tapered borosilicate glass metering tube and metering float
Model code
Revision decoded from code G
Revision G
Construction
End block material decoded from code B
Brass
Family materials
Brooks 1350G/1355G documentation lists borosilicate glass, brass, aluminum, 316 stainless steel, clear polycarbonate, milk white polycarbonate, and Teflon materials of construction depending on configuration
Flow path
Tube and float decoded from code F3A
R-6-15-B G tube with glass float and standard 1355 accuracy custom decal scale context
Capacity-table context for decoded tube and float
Brooks 1350G/1355G tables list the R-6-15-B G tube with glass float at 560 cc/min water and 23 SLPM air full-scale reference capacity; actual use depends on the installed custom scale and process conditions
Performance
1355G accuracy context
Brooks 1350G/1355G documentation lists 1355G accuracy as +/-3% at reference conditions; the standard custom-decal float/scale code used here is listed in standard 1355 accuracy context
Repeatability
Brooks 1350G/1355G documentation lists repeatability as 0.25% full scale
Pressure and temperature
Family pressure and temperature rating
Brooks 1350G/1355G documentation lists 200 psig from 33 deg F to 250 deg F / 13.8 bar from 1 deg C to 121 deg C
Seals
Packing and seals decoded from code A
Buna tube packing with Buna O-rings
Connections
Fitting and connection decoded from code C
316 stainless steel 1/8 inch NPT end fitting
Controls
Valve decoded from code A
Valve plug
Valve cavity/controller location decoded from code 1
Inlet valve/controller location with back/back connection orientation context
Options
Alarm, accessory, and certification codes
Codes A/A/A indicate no alarm option, no accessory selection, and no certification option
Observed configuration
Exact-SKU listing context
Exact-SKU distributor evidence and stored Sonisys auction records describe this exact manufacturer part number with 10 to 100 SCFH and 1/8 inch NPT wording; this is retained as observed listing context and should be verified against the physical custom decal scale
Applications
Application domain
Low-flow gas and liquid indication, purge-flow service, laboratory/process support, and equipment-maintenance contexts where the configured materials, tube, float, fittings, seals, valve-plug configuration, and calibration match the process
Configuration
Configured-unit rule
Installed tube condition, float condition, custom scale markings, process fluid, flow range, calibration basis, seals, fittings, valve-cavity arrangement, and process compatibility must be verified from the physical unit and OEM documentation
