01B61001243
Brooks Sho-Rate Glass-Tube Variable-Area Flowmeter
About this part
01B61001243 identifies a Brooks Sho-Rate flowmeter. Sho-Rate instruments provide local flow indication using a float in a tapered glass metering tube and are offered for gas or liquid service. The identifier does not correspond to a published Brooks base-model code, so the unit's model, scale, flow range, accuracy, connections, valve arrangement, and material configuration must be read from its nameplate and scale before service or replacement selection
Configurations vary. Verify the exact unit before choosing a replacement.
Key Facts
Specifications
| Record identifier | 01B61001243 |
| Manufacturer | Brooks Instrument |
| Product family | Sho-Rate |
| Instrument type | Glass-tube variable-area flowmeter (rotameter) |
| Operating principle | A float rises within a tapered glass metering tube to provide local flow-rate indication |
| Applicable media | Gas or liquid, subject to the configured scale, tube, float, seals, wetted materials, and process conditions |
| Metering-tube material | Borosilicate glass across the documented Sho-Rate families |
| Base function | Local flow indication; needle valves and flow-controller interfaces are configuration options and are not established for 01B61001243 |
| Exact Brooks model code | Not established; 01B61001243 is not among the published current or legacy Sho-Rate base-model identifiers |
Published Sho-Rate variants
Brooks has issued materially different current and legacy Sho-Rate variants. These ratings identify the possible family context and are not specifications for 01B61001243 without a matching nameplate model.
| Published variant | Status | Nominal scale length | Published standard accuracy | Published repeatability |
|---|---|---|---|---|
| 1250A | Current family | 65 mm | ±5% of full scale | 0.25% of full scale |
| 1255A | Current family | 150 mm | ±3% of full scale | 0.25% of full scale |
| 1350G | Current family | 65 mm | ±5% at reference conditions | 0.25% of full scale |
| 1355G | Current family | 150 mm | ±3% at reference conditions | 0.25% of full scale |
| 1358F | Current family | 75 mm | ±10% of full scale | 0.5% of full scale |
| 1350E | Legacy family | 65 mm | ±10% of full scale | 0.5% of full scale |
| 1355E | Legacy family | 150 mm | ±5% of full scale | 0.5% of full scale |
Configuration identification
A complete Brooks model code and the tube markings are required to select technical data or a replacement.
- Record the full Brooks model number and serial number from the instrument label.
- Record the tube number, float material or float code, scale units, calibrated medium, specific gravity or density, viscosity, reference pressure, and reference temperature.
- Verify end-block and fitting materials, connection size and type, seal materials, valve type and location, port orientation, alarm hardware, and any attached flow controller.
- Do not infer a flow range from the Sho-Rate family name; Brooks publishes multiple tube-and-float combinations and direct-read scales.
Glass-tube safety
The applicable Brooks manual and the exact configured pressure and temperature limits must be confirmed before installation or operation.
- Mount the meter vertically as specified for its model, with flow entering through the lower fitting.
- Do not exceed the configured pressure or temperature rating, and avoid pressure and flow surges.
- Do not service or disassemble the instrument while it is pressurized.
- Keep required protective sleeves, windows, and shields installed and securely fastened.
- Brooks warns against toxic fluids and fluids that chemically attack glass, including steam, alkalis, fluorine, hydrofluoric acid, molten metal, and water above 140°F (60°C).
