Variable Area Flow Meters
1355EGN1CKX9J
Brooks Instrument Sho-Rate 1355E Glass-Tube Variable-Area Flow Meter
About this part
Brooks 1355EGN1CKX9J is a configured legacy Sho-Rate 1355E “150” glass-tube variable-area flow meter. The 1355E uses a nominal 150 mm scale and a tapered borosilicate-glass metering tube with a float. Its GN1CKX9J configuration suffix is not fully decoded by the published standard-capacity tables; verify the calibrated fluid, range, float, seals, connections, and valve arrangement from the tube markings, nameplate, or Brooks serial-number record
Configurations vary. Verify the exact unit before choosing a replacement.

Key Facts
Specifications
| Manufacturer | Brooks Instrument |
| Product line | Sho-Rate “150” |
| Base model | 1355E legacy series |
| Measuring principle | Variable area; tapered glass metering tube and float |
| Nominal scale length | 150 mm |
| Metering tube | Borosilicate glass |
| Accuracy options | 1355E family standard: ±5% of full scale; documented calibrated scale configurations: ±2% of full scale. The exact GN1 configuration must be verified before assigning either value to this unit |
| Repeatability | 0.5% of full scale |
| Pressure and temperature rating | 1355E family rating: 200 psig (13.8 bar) from 33°F to 250°F (1°C to 121°C); CRN-certified configurations are rated 170 psig over the same temperature range. Attached components may impose lower limits |
| Required orientation | Install vertically and plumb, with flow entering the bottom connection and leaving the top connection |
| Product status | Legacy product; Brooks identifies the current Sho-Rate series as the replacement product line |
What Does 1355EGN1CKX9J Mean?
The base model is documented, while the configured suffix contains values that cannot be safely converted into exact unit specifications from the public ordering tables alone.
| Segment | Field | Interpretation |
|---|---|---|
| 1355E | Base model and revision | Legacy Brooks Sho-Rate “150” glass-tube variable-area flow meter with a nominal 150 mm scale. |
| GN1 | Tube, float, and scale configuration | Configured scale-on-tube identifier. GN1 does not appear in the published standard air/water capacity-code tables; do not assert a fluid, range, float material, or accuracy class without the tube markings or Brooks serial record. |
| C | Construction and seal selection | Documented field position, but the exact material interpretation is not established for this configured unit. |
| K | Process-connection selection | Documented field position; the exact fitting material, size, and type require label or manufacturer-record confirmation. |
| X | Valve or controller selection | Documented field position; the public family material does not establish the exact valve arrangement for this suffix. |
| 9 | Valve/controller location and connection orientation | Documented field position; do not assert a location or orientation from this value without the applicable revision-specific ordering record. |
| J | Accessory or special-option selection | Configured option value whose exact interpretation requires the Brooks serial-number record or physical-label evidence. |
Configuration Verification
The calibrated metering tube and complete nameplate are the controlling references for this configured meter.
Installation and Service Notes
Applicable operating guidance from the 1350E/1355E installation manual.
- Support the process piping so it does not place strain on the meter.
- Read flow at the center of the spherical float.
- An integral needle valve is intended for fine flow control, not tight shutoff; use a separate upstream shutoff valve when tight isolation is required.
- After reassembly, leak-test the meter with air at a minimum of 15 psig at room temperature.
- Dirt on the tube or float can cause inaccuracy or float sticking; inspect and clean them periodically.
Legacy and Replacement Relationship
Brooks lists the 1350E/1355E series as a legacy glass-tube variable-area flow-meter family and directs users to the current Sho-Rate product line. The current 1355G has revised construction and performance data; it is not an automatic like-for-like replacement for the GN1CKX9J configuration. Match the calibrated range, fluid, scale, connections, wetted materials, seals, valve arrangement, and certification before substitution.
