Brooks Instrument Sho-Rate 1350G Variable Area Flowmeter with Flow Controller
About this part
1350GBK3EAJQ5AAA is a configured Brooks Instrument Sho-Rate 1350G glass tube variable area flowmeter. Official Brooks 1350G/1355G documentation identifies the 1350G as a 65 mm Sho-Rate flow indicator, and the model-code table decodes this configured code as a Revision G unit with brass end blocks, an R-2-65-D G tube, tantalum float with custom decal scale, Buna packing and O-rings, 316 stainless 1/4 in. NPT fittings, and an integrally mounted 88/8900 brass flow controller interface. Stored auction evidence for this exact identifier includes 2.5-11 SCFH and 2.5-12 SCFH listing contexts; those are retained only as observed listing context, while official flow capacity should be checked against the installed scale and calibration label
Unit-specific configuration
Historical listing records identify this part as 11 SCFH. Exact gas, range, fittings, valve configuration, and communication interface must be verified from the physical unit label.
Configurations vary. Verify the exact unit before choosing a replacement.
Key Facts
Specifications
| Device type | Glass tube variable area flowmeter |
| Series family | Brooks Sho-Rate 1350G/1355G Series glass tube variable area flowmeters |
| Configured model | 1350G, Revision G; official Brooks model-code documentation lists 1350 as the 65 mm Sho-Rate size 1-6 flow indicator |
| Measuring principle | Variable area rotameter using a tapered borosilicate glass metering tube and metering float |
| Tube and float decoded from model code | Code K maps to tube R-2-65-D G for the 1350G; code 3E maps to a tantalum float with standard 1350 custom decal scale selection |
| Official capacity context for decoded tube and float | Brooks 1350G/1355G capacity tables list R-2-65-D G with a tantalum float at 2.7 GPH / 10.0 LPH water and 12 SCFH / 310 NLPH air at stated reference conditions; verify the installed scale and calibration label before treating this as the unit's usable range |
| End block material | Model-code position VI code B indicates brass end block material |
| Packing and seals | Model-code position X code A indicates Buna tube packing and Buna meter/valve O-rings |
| Connection | Model-code position XI code J indicates 316 stainless steel 1/4 in. NPT end fittings |
| Valve/controller interface | Model-code position XII code Q indicates an integrally mounted 88/8900 brass flow-controller interface with Cartridge II/III valve and Buna diaphragm |
| Controller location and orientation | Model-code position XIII code 5 indicates outlet location with back/back connection orientation |
| Alarm, option, and certification codes | Final codes A/A/A indicate no alarm option, no additional listed option, and no listed certification option in the Brooks model-code table |
| 1350G family accuracy and repeatability context | Brooks 1350G/1355G documentation lists 1350G accuracy as +/-5% at reference conditions and repeatability as 0.25% full scale for the family; configured scale and calibration details remain unit-specific |
| Pressure and temperature family rating | Brooks 1350G/1355G documentation lists 200 psig at 33 degrees F to 250 degrees F / 13.8 bar at 1 degree C to 121 degrees C for the family |
| Application domain | Low-flow gas and liquid indication or control, especially purge applications, depending on the configured tube, float, scale, valve, and process connection |
| Stored auction scale contexts | Stored Sonisys auction records for this exact identifier include 2.5-11 SCFH and 2.5-12 SCFH contexts; these are observed listing contexts, not independent official model-wide specifications |
