1355EAH2CKE1L identifies a Brooks Sho-Rate 1355E “150” low-flow variable-area flowmeter. The instrument uses a tapered borosilicate-glass metering tube and a float, with a nominal 150 mm scale. The suffix is configuration-bearing, but the published Brooks code tables do not support a defensible exact flow range, float material, scale, connection, valve, seal, or option assignment for the complete AH2CKE1L suffix. Those attributes require the unit label or Brooks order record
Configurations vary. Verify the exact unit before choosing a replacement.

Brooks Sho-Rate “150” Model 1355E
Measurement
Measuring principle
Variable area; tapered glass metering tube and metering float
Mechanical
Nominal scale length
150 mm
Configuration
First tube-code digit
A; Brooks maps this position to an R-2-15-A metering tube, but the complete AH2 scale/float code remains unresolved
Materials
Metering-tube material
Borosilicate glass
Performance
Published 1355E standard family accuracy
±5% of full scale; do not assert this as the exact AH2 configured-unit accuracy
Repeatability
0.5% of full scale
Pressure and temperature
Published family operating envelope
200 psig from 33°F to 250°F (1°C to 121°C); CRN-certified configurations are rated 170 psig over the same temperature range
Installation
Required orientation
Mount within 6° of true vertical, with the inlet in the bottom end fitting
Operation
Flow-reading reference
Center of the spherical float
What Does 1355EAH2CKE1L Mean?
The base model and first tube-code position are supported by Brooks documentation. Unresolved suffix values are retained exactly and are not normalized to another code.
Segment
Field
Interpretation
1355E
Base model
Brooks Sho-Rate “150” glass-tube variable-area flowmeter with a nominal 150 mm scale.
A
Tube code, first configuration position
Brooks maps A to the R-2-15-A metering tube.
H2
Float, accuracy and scale configuration
The complete H2 value does not match a published 1355E second-and-third-position combination in the reviewed Brooks tables. No float material, accuracy class, scale type or flow range is assigned. Do not transpose it to 2H.
C
Fitting and connection field
Value C is retained but not decoded. Confirm the process connection from the label or Brooks order record.
K
Valve field
Value K is retained but not decoded. Do not assert a valve type or control function.
E
Packing and O-ring field
Value E is retained but not decoded. Do not assert an exact elastomer or packing material.
1
Valve-location field
Value 1 is retained but not decoded for this legacy configuration. Do not assert inlet or outlet valve placement.
L
Options field
Value L is retained but not decoded. Do not assert an accessory, construction option or certification.
Installation and Operating Notes
Install the meter within 6° of true vertical and support the piping so it does not strain the meter.
Perform a final leak test before introducing process fluid.
Read indicated flow at the center of the spherical float.
An integral needle valve, when fitted, is intended for fine control. Use a separate upstream shutoff valve when tight shutoff is required.
After reassembly, Brooks specifies an air leak test at a minimum of 15 psig at room temperature.
