What Does 1358E1C1EC2A1A Mean?
The configured suffix follows the Brooks 1358 ordering-code structure. The base revision letter differs from current ordering literature, which now uses 1358F.
| Segment | Field | Interpretation |
|---|---|---|
| 1358E (I–V) | Base model | Legacy Sho-Rate 1358 base designation. Current June 2026 ordering literature uses 1358F for Sho-Rate “50,” Size 8. |
| 1 (VI) | Tube | R-8M-75-1 metering tube. |
| C (VII) | Float | 316 stainless-steel 8-RJ-23 float; documented maximum capacity is 2.5 gpm water. |
| 1 (VIII) | Scale arrangement | Scale applied directly to the metering tube. |
| E (IX) | Scale inscription | GPM liquid scale for specific gravity 1.0 and viscosity 1.0 cP; standard ±10% full-scale accuracy. |
| C (X) | Packing and O-rings | Viton tube packing and Viton O-rings. |
| 2 (XI) | Fittings and process connection | 316 stainless-steel fittings and adapters with 3/8-inch NPT connections. |
| A (XII) | Valve configuration | No valve; plain inlet end fitting. |
| 1 (XIII) | Connection orientation | Inlet port rear and outlet port rear. |
| A (XIV) | Accessories | None. |
Installation and Process-Safety Notes
- Install the meter vertically, within 6 degrees of true vertical, with the inlet at the bottom.
- Initiate flow slowly and check the inlet and outlet connections for leakage before raising the system to operating pressure.
- Do not use the glass-tube meter with toxic fluids or media that attack glass, including water above 140°F, steam, alkalis, fluorine, hydrofluoric acid, or molten metal.
- Confirm that all seal, packing, O-ring, and fitting materials are chemically compatible with the process fluid and operating conditions.
