Brooks Instrument Sho-Rate 1350E Direct-Read Metering Tube

About this part

S-925-G-288-WAA is a Brooks Instrument direct-reading metering tube observed in a legacy Sho-Rate Model 1350E variable-area flowmeter assembly. The archived example is associated with assembly code 1350END2JJA1H and a 100–650 Ln/h air scale referenced at 21.1°C. Replacement selection must preserve the complete assembly code, calibrated fluid, scale conditions, tube-and-float combination, and process requirements

Configurations vary. Verify the exact unit before choosing a replacement.

Observed Assembly and Calibration Context

The associated code places the observed example in Brooks’ legacy Model 1350E Sho-Rate “50” platform. The range and calibration marking are exact-example observations rather than universal S-925-family ratings.

Associated assembly/model code1350END2JJA1H

Meter platformSho-Rate Model 1350E “50”

Observed direct-read range100–650 Ln/h

Observed calibrated fluidAir

Observed reference temperature21.1°C

Applicability boundaryDo not apply this range, fluid, or reference condition to another S-925 tube without matching exact configuration evidence.

Replacement and Service Notes

Brooks classifies the 1350E/1355E platform as a legacy glass-tube variable-area flowmeter and identifies the current Sho-Rate series as its replacement product line.
A replacement tube must match the meter assembly, calibrated fluid and conditions, scale duty, and float combination. The S-925 identifier alone does not establish the fitting, seal, float, valve, or certification configuration.
Current revision-G specifications must not be substituted for legacy revision-E performance. Brooks documents ±5% full-scale accuracy and 0.25% full-scale repeatability for the current 1350G, compared with ±10% and 0.5% for the legacy 1350E.
Successor-product status does not establish direct mechanical or calibration interchangeability. Confirm replacement suitability with Brooks Instrument using the full assembly code and operating conditions.
