1303AL12BA11A is a configured Brooks Instrument glass tube variable-area flowmeter identifier observed in Sonisys auction records and exact surplus listing context. Official Brooks GT1600 documentation provides current glass-tube variable-area and GT130x retrofit context, but no verified official Brooks PDF or product page is currently available that names the full configured identifier 1303AL12BA11A. Flow range, tube, float, scale, process fluid, connection, materials, pressure rating, temperature rating, alarms, and service suitability should be verified from the physical unit label and scale
Configurations vary. Verify the exact unit before choosing a replacement.

Specifications
Identification
Configured part identifier
1303AL12BA11A
Device type
Glass tube variable-area flowmeter / rotameter
Manufacturer context
Exact surplus listing evidence identifies the part as a Brooks flow meter; Brooks Instrument is the flowmeter manufacturer context used for this record
Legacy family context
Brooks-authored glass-tube quick-start documentation lists GT1303 among legacy Brooks glass-tube variable-area flowmeter models, and current Brooks GT1600 documentation describes retrofit support for GT130x meters
Flow
Measuring principle
Variable-area flow indication using a tapered glass metering tube and float
Observed exact-unit tube and scale context
Stored Sonisys listing evidence for this exact configured identifier includes GPM scale wording, liquid specific gravity 1.0, viscosity 1.0 cP, tube R-10M-75-3, and approximately 1 inch NPT wording; these are observed listing values, not an official build sheet
R-10M-75-3 family table context
Brooks GT1600 capacity tables include size-10 R-10M-75-3 tube rows for water and air capacity context; the actual float, scale range, and service fluid for 1303AL12BA11A must be verified from the unit
Construction
Current retrofit family material context
Brooks GT1600 documentation describes borosilicate glass metering tubes, 316/316L stainless steel process fittings, 316 stainless steel housings and hardware, polycarbonate window and safety shield, and selectable wetted O-ring materials for the current retrofit family
Connections
Current retrofit family connection context
Brooks GT1600 documentation lists NPT threaded and ANSI 150 lb RF flanged process connection options in horizontal and vertical orientation configurations; exact connection details for 1303AL12BA11A must be verified from the physical unit
Performance
Current retrofit family accuracy context
Brooks GT1600 documentation lists standard accuracy options of +/-10%, +/-5%, and +/-2% full scale, with an optional +/-1% full-scale option depending on selected model and tube; this is family context, not an exact 1303AL12BA11A certificate
Current retrofit family repeatability
Brooks GT1600 documentation lists repeatability as less than or equal to 0.5% full scale for the current family
Pressure and temperature
Current retrofit family limits
Brooks GT1600 documentation lists pressure ratings by tube size and process connection and operating fluid temperature limits of 33 to 250 deg F / 1 to 121 deg C; use the physical unit label for this configured part
Options
Current retrofit family options
Brooks GT1600 documentation describes optional high/low flow alarms, panel or wall mounting, and optional integral needle valve configurations
Configuration
Configured-unit rule
Tube, float, scale range, direct-reading units, calibrated fluid, connection size, orientation, seal material, pressure rating, temperature rating, alarms, valves, and approvals vary by configured code and unit label
Applications
Application domain
Industrial liquid or gas flow indication where a glass tube variable-area meter is suitable for the configured materials, pressure, temperature, and process-fluid limits
