Brooks Instrument Sho-Rate Glass-Tube Variable-Area Flowmeter
About this part
Brooks Instrument 1355EC2CA1E1A is a legacy Sho-Rate “150” Model 1355E glass-tube variable-area flowmeter. The C2C segment specifies an R-2-15-AAA borosilicate-glass metering tube, sapphire float, standard ±5% full-scale accuracy, and a detachable special single scale. The installed scale and calibration record define the configured process fluid, engineering units, and operating range
Configurations vary. Verify the exact unit before choosing a replacement.

| Reading point | Read flow at the center of the spherical float |
What Does 1355EC2CA1E1A Mean?
The manufacturer’s 1355E tube-and-float tables decode the model and C2C segment. The remaining suffix is retained without unsupported option-level interpretation.
| Segment | Field | Interpretation |
|---|---|---|
| 1355E | Meter series | Sho-Rate “150” glass-tube variable-area flowmeter with a nominal 150 mm scale. |
| C | Metering-tube selection | R-2-15-AAA tube. |
| 2C | Float, accuracy, and detachable scale | Sapphire float; standard 1355E accuracy of ±5% full scale; special single scale. |
| A1E1A | Remaining configuration fields | Construction, connection, valve/location, and option values retained exactly; individual meanings require an unambiguous manufacturer Table 5 reading or physical-label evidence. |
Scale and Capacity Interpretation
The special single scale is configured for a particular application. The published 73.3 sccm air and 1.02 cc/min water values are reference maximum capacities for the R-2-15-AAA tube with a sapphire float, not proof of the unit’s calibrated fluid, scale units, or final operating range.
Installation and Reading Notes
- Install the flowmeter within 6° of true vertical, with flow entering the bottom fitting.
- Determine indicated flow from the center of the spherical float.
- Perform a final leak test after installation and before introducing process fluid.
- Do not use an integral needle control valve as a positive shutoff; provide a separate shutoff valve when tight closure is required.
Legacy and Replacement Status
Brooks lists the 1350E/1355E series as a legacy glass-tube variable-area flowmeter and links the current Sho-Rate series as its replacement product. This does not establish drop-in interchangeability. Current 1355G accuracy, repeatability, ordering codes, and connection options must not be applied to this 1355E configuration without a documented retrofit comparison.
