Brooks Sho-Rate 150 Variable-Area Flowmeter
About this part
Brooks 1355EF2DAJR1A is a legacy Sho-Rate 1355E “150” variable-area flow indicator. The configured identifier selects an R-2-15-D borosilicate metering tube, Carboloy float, standard ±5% full-scale accuracy, and a special single scale. The process fluid and scale inscription are order-specific calibration data and must be confirmed from the installed tube, unit label, or Brooks order record
Configurations vary. Verify the exact unit before choosing a replacement.
Key Facts
Specifications
| Manufacturer | Brooks Instrument |
| Product line | Sho-Rate |
| Legacy model | 1355E “150” |
| Complete configured identifier | 1355EF2DAJR1A |
| Measuring principle | Variable area with tapered glass metering tube and float |
| Meter size | Size 2 |
| Metering tube | R-2-15-D |
| Metering-tube material | Borosilicate glass |
| Float material | Carboloy® |
| Scale selection | Special single scale; inscription and calibrated fluid are order-specific |
| Accuracy | ±5% of full scale, standard Model 1355 configuration |
| Repeatability | 0.5% of full scale |
| Reference maximum capacity | 31.9 cc/min water or 1170 scc/min air for the R-2-15-D tube with Carboloy float; direct-reading scales may terminate at a different maximum |
| Air reference conditions | 14.7 psia and 70°F |

| Nominal scale length | 150 mm |
| Mounting orientation | Within 6° of true vertical |
| Flow direction | Inlet at the bottom end fitting; upward flow through the metering tube |
Model-code interpretation
The revision-E tube and scale tables must be used for this identifier. Later 1355G codes are not interchangeable with the 1355E code system.
| Code segment | Meaning | Applicability |
|---|---|---|
| 1355E | Sho-Rate “150” glass-tube variable-area flow indicator with nominal 150 mm scale | Exact model series |
| F | R-2-15-D metering tube for Model 1355E | Exact configured unit |
| 2D | Standard-accuracy Carboloy float with a special single scale | Exact configured unit |
| AJR1A | Remaining packing, connection, valve/location, and option segment retained as part of the exact identifier | Confirm detailed expansion from the revision-E ordering table or Brooks order record before specifying replacement hardware |
Scale and capacity interpretation
The 2D code selects a special single scale but does not establish a universal process fluid, engineering unit, or printed range. For the selected R-2-15-D tube and Carboloy float, Brooks lists reference maxima of 31.9 cc/min water and 1170 scc/min air. A direct-reading calibrated scale may end at a different value, so the tube inscription controls service identification.
Legacy status and replacement
Brooks classifies the 1350E/1355E series as legacy equipment and directs users to the current Sho-Rate product line.
