Brooks Instrument Sho-Rate 1355G Glass Tube Variable Area Flowmeter
About this part
1355GAE3CBJU1AAA is a configured Brooks Instrument Sho-Rate 1355G glass tube variable-area flowmeter identifier. Official Brooks 1350G/1355G documentation identifies 1355 as the 150 mm Sho-Rate Size 1-6 flow indicator base model and provides the model-code table used to decode this configured code as a Revision G meter with 316 stainless steel end blocks, R-6-15-A G tube context, sapphire float with custom decal scale selection, Viton tube packing and Viton O-rings, 316 stainless steel 1/4 inch NPT connection fittings, medium-flow 316 stainless steel Cartridge III valve, inlet/back-back orientation, no alarm, no additional option, and no certification option. Exact process fluid, custom scale inscription, calibration basis, pressure/temperature suitability, and installed condition should be verified from the physical unit label and tube scale
Configurations vary. Verify the exact unit before choosing a replacement.
Code U indicates a medium-flow 316 stainless steel Cartridge III valve; code 1 indicates inlet location with back/back connection orientation
Alarms, options, certifications
Codes A/A/A indicate no alarm, no additional option, and no certification option in the Brooks model-code table
Flow
Measuring principle
Variable-area flow indication using a tapered borosilicate glass metering tube and metering float
Decoded tube/float capacity context
For the R-6-15-A G tube with sapphire float, Brooks 1355G documentation lists full-scale water capacity of 320 cc/min and full-scale air capacity of 12 SLPM at stated reference conditions; use the physical custom decal and calibration data for the exact scale
Performance
Family accuracy and repeatability
Brooks documentation lists 1355G accuracy as +/-3% at reference conditions and repeatability as 0.25% full scale; configured custom-decal accuracy should be verified from the unit documentation
Pressure/Temperature
Family pressure-temperature context
Brooks 1350G/1355G documentation lists 200 psig from 33 F to 250 F / 13.8 bar from 1 C to 121 C; verify the configured unit and service conditions before using this limit
Materials
Family construction context
Brooks documentation describes borosilicate glass, brass, aluminum, 316 stainless steel, clear polycarbonate, milk white polycarbonate, and Teflon materials depending on configured options
Connections
Family connection options
Brooks 1350G/1355G documentation lists NPT, compression, RC, VCR, and hose connection options depending on model-code configuration
Applications
Application domain
Low-flow gas and liquid indication or control, particularly purge applications, depending on tube, float, valve, scale, and calibration configuration
Configuration
Configured-unit rule
Verify tube/float code, direct-read or custom decal scale, process fluid, calibration conditions, valve trim, connection style, seals, pressure/temperature suitability, and service requirements from the physical meter and application
