Brooks Instrument Sho-Rate 1350G Variable-Area Flowmeter with Inlet Low-Flow Valve
About this part
Brooks Instrument 1350GAK3BBNT1AAA is a 65 mm Sho-Rate 1350G Revision G glass-tube variable-area flowmeter. Its model code specifies 316 stainless-steel end blocks, an R-2-65-D G metering tube, stainless-steel float, custom decal scale, Viton® tube packing and O-ring, 316 stainless-steel 1/4-inch NPT fittings with locknuts, and an inlet-mounted low-flow Cartridge III valve. No alarm, additional construction option, or optional certification is selected. The custom decal’s fluid, units, and calibrated range must be read from the unit scale or calibration record
Configurations vary. Verify the exact unit before choosing a replacement.

What Does 1350GAK3BBNT1AAA Mean?
Brooks defines the identifier as a sequence of configuration fields. The full code can be decoded without normalizing or altering the supplied part number.
| Segment | Field | Interpretation |
|---|---|---|
| 1350 | Basic model | 65 mm Sho-Rate size 1–6 flow indicator |
| G | Model revision | Revision G |
| A | End-block material | 316 stainless steel |
| K | Metering tube | R-2-65-D G tube for model 1350 |
| 3B | Float and scale selection | Stainless-steel float, standard accuracy designation, custom decal scale |
| B | Tube packing and O-ring | Viton® packing and Viton® meter/valve O-ring |
| N | End fitting | 316 stainless steel, 1/4-inch NPT threaded fitting with locknut |
| T | Valve | Low-flow Cartridge III valve, 316 stainless steel |
| 1 | Valve location and orientation | Valve at inlet; inlet and outlet connections oriented to the back |
| A | Alarm | None |
| A | Additional option | None |
| A | Optional certification | None selected |
Reference Capacity for the Decoded Tube and Float
For the R-2-65-D G tube with a stainless-steel float, Brooks publishes the following full-scale reference capacities. Because this unit has a custom decal, these values do not establish its actual scale, process fluid, or calibration conditions.
| Medium | Published full-scale capacity | Applicability |
|---|---|---|
| Water | 1.6 gph / 6.3 L/h | Reference capacity for the decoded tube-and-float combination |
| Air | 7.9 scfh / 200 normal L/h | Reference capacity for the decoded tube-and-float combination; standard-unit air value is stated at 70°F and 14.7 psia |
Accuracy Qualification
The configured code establishes a standard rather than calibrated accuracy selection, but the current Brooks documents contain conflicting numeric descriptions. A unit calibration record or manufacturer clarification is required before assigning one numeric tolerance to this exact configuration.
Installation Essentials
Brooks specifies the following installation practices for Sho-Rate 1350G flowmeters.
- Mount the flowmeter within 6 degrees of true vertical.
- Use the bottom end fitting as the inlet.
- Support the process piping so it does not impose undue strain on the meter.
- Perform a final system-plumbing and meter leak test before introducing process fluid.
