1355GAC3EBJU1AAA is a configured Brooks Instrument Sho-Rate 1355G glass tube variable-area flowmeter identifier. Official Brooks 1350G/1355G documentation identifies the 1355G family as a 150 mm Sho-Rate glass tube flow indicator and provides model-code tables that decode this configured code as a Revision G meter with 316 stainless steel end blocks, an R-2-15-C G tube, tantalum float with custom decal scale selection, Viton packing and O-rings, 316 stainless steel 1/4 inch NPT fittings, a medium-flow 316 stainless steel Cartridge III valve, inlet valve/controller location, and no alarm, accessory, or certification option. Exact service suitability, installed condition, and process-specific scale details should be verified from the physical unit label, tube, float, scale, and OEM records
Configurations vary. Verify the exact unit before choosing a replacement.

1355GAC3EBJU1AAA
Device type
Glass tube variable-area flowmeter / rotameter
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 glass metering tube and metering float
Model code
Revision decoded from code G
Revision G
Construction
End block material decoded from code A
316 stainless steel
Packing and seals decoded from code B
Viton tube packing with Viton meter/valve O-rings
Flow path
Tube decoded from code C
R-2-15-C G tube for the 1355G family
Float and scale decoded from code 3E
Tantalum float with custom decal scale selection in the standard 1355 direct-read context
Capacity-table context for decoded tube and float
Brooks 1350G/1355G tables list the R-2-15-C G tube with tantalum float at 360 cc/min water and 11 SLPM air full-scale reference capacity; actual use depends on the installed custom decal scale and process conditions
Performance
1355G accuracy context
Brooks 1350G/1355G documentation lists 1355G accuracy as +/-3% at reference conditions; the configured 3E scale selection and physical scale markings should be checked for the applied 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
Connections
Fitting and connection decoded from code J
316 stainless steel 1/4 inch NPT fittings
Controls
Valve decoded from code U
Cartridge III medium-flow valve, 316 stainless steel
Valve location decoded from code 1
Inlet valve/controller location with inlet-back and outlet-back connection orientation
Options
Alarm, accessory, and certification codes
Codes A/A/A indicate no alarm option, no accessory selection, and no certification option
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, valve, scale, and calibration match the process
Configuration
Configured-unit rule
Installed tube condition, float condition, scale markings, process fluid, flow range, calibration basis, seals, fittings, valve condition, and process compatibility must be verified from the physical unit and OEM documentation
Observed configuration
Stored and seller listing context
Stored Sonisys records and external seller listings identify this exact configured code as a Brooks Sho-Rate variable-area flow meter with 2.1-21 SCFH and 1/4 inch NPT wording; this is observed item context, not a separate official model-wide specification
