Brooks Instrument Sho-Rate 1358 Glass-Tube Variable-Area Flowmeter
About this part
Brooks Instrument 1358-01B1CAC is an exact identifier associated with a Sho-Rate Model 1358 size-8 glass-tube variable-area flowmeter. Model 1358 provides direct visual flow indication for gas or liquid service. The suffix does not conform to Brooks Instrument’s current June 2026 ordering-code table, so the unit’s tube and float combination, scale, wetted materials, valve, process connections, orientation, and accessories require confirmation from a matching Brooks order record or the physical unit label
Configurations vary. Verify the exact unit before choosing a replacement.
Key Facts
Specifications
| Measurement principle | Variable-area flow indication using a glass metering tube and float |
| Standard accuracy | ±10% of full scale |
| Repeatability | 0.5% of full scale |
| Rangeability | 10:1 |
| Available water capacities | 0.8, 1.5, 2.5, 3.5, or 5.0 gpm, depending on the selected float; the exact unit range is not established |
| Available air capacities | 3.4, 6.0, 12.0, or 15.0 scfm at 70°F and 14.7 psia, depending on the selected float; the exact unit range is not established |
| Standard pressure and temperature rating | 200 psig from 33°F to 250°F (1°C to 121°C); CRN-certified configurations are rated 100 psig over the same temperature range |
| Metering tube | Heavy-wall precision-bore borosilicate glass |
| Float material | 316 stainless steel |
| Scale | 75 mm nominal; standard scale is fused on the tube, with direct-read and detachable-scale configurations available |
| Process connections | Standard horizontal female 3/8-inch NPT threaded adapters; fitting material and locknut options vary by configuration |
| End-fitting materials | Chrome-plated brass or 316 stainless steel, depending on configuration |
| Side plates | Black anodized aluminum standard; configuration-specific alternatives are available |
| Valve and controller options | No valve, an integral inlet or outlet needle valve, or provisions for a compatible flow controller, depending on configuration |
What Does 1358-01B1CAC Mean?
The exact identifier uses a suffix format that is not defined by the current Brooks Instrument Model 1358 ordering table. Only the Model 1358 family portion can be decoded conservatively.
| Segment | Field | Interpretation |
|---|---|---|
| 1358 | Meter series | Sho-Rate Model 1358, a size-8 glass-tube variable-area flowmeter. |
| - | Identifier separator | Retained as part of the exact identifier. The current manufacturer model-code table does not define a hyphen in this position. |
| 01B1CAC | Configuration suffix | Not mapped by the June 2026 manufacturer code table. That table begins with 1358F and separately encodes the tube, float, scale, packing and O-rings, fittings, valve, connection orientation, and accessories. Do not assert those configured options without a matching Brooks record or readable unit label. |
Installation and Safety Notes
Model 1358 is a pressurized glass-tube instrument and must be installed and serviced in accordance with the manufacturer’s operating manual.
- Mount the flowmeter within 6 degrees of true vertical, with the inlet connection at the bottom.
- Keep the protective tube sleeve and meter windows secured, avoid pressure and flow surges, and fully depressurize the process before service.
- If adjacent inlet and outlet isolation valves are closed in liquid service, drain the meter to prevent damaging thermal expansion.
- The 250°F family temperature rating does not override fluid-compatibility restrictions. Brooks warns against toxic fluids and media that react with glass, including water above 140°F, steam, alkalis, fluorine, hydrofluoric acid, and molten metal.
- Confirm that the configured packing, O-rings, fittings, and valve materials are compatible with the process fluid before installation.
