Brooks Instrument Sho-Rate Model 1358 Variable Area Flowmeter
About this part
1358F1B4FC2A6A is a configured Brooks Instrument Sho-Rate Model 1358 glass tube variable-area flowmeter. Official Brooks 1358 documentation identifies Model 1358 as a Sho-Rate "50" Size 8 rotameter family with borosilicate glass metering tube, 316 stainless float options, 3/8 inch NPT connection options, configurable scale inscription, valve, seal, fitting, and connection-orientation options. distributor and stored auction evidence identify this exact code with 1.5-15 SCFM and 3/8 inch NPT context; treat that as observed configured-unit evidence and verify the physical scale and nameplate before replacement
Configurations vary. Verify the exact unit before choosing a replacement.

Brooks Model 1358 data sheet lists repeatability as 0.5% full scale
Rangeability
10:1
Pressure and temperature
Standard pressure and temperature rating
Brooks Model 1358 documentation lists 200 psig at 33 deg F to 250 deg F / 1 deg C to 121 deg C, with separate CRN certification context at 100 psig over the same temperature range
Configuration
Tube code
1 - R-8M-75-1
Float code
B - 8-RJ-10, 316 stainless steel
Scale inscription code
F - special inscription, standard 10% accuracy
Tube packing and O-ring code
C - Viton tube packing and Viton O-ring
Fitting and adapter code
2 - 3/8 inch NPT connection with 316 stainless steel fitting and adapter
Valve configuration code
A - no valve, plain end fitting on inlet
Accessories code
A - none
Configured-unit rule
Scale plate arrangement, exact scale range, calibrated gas or liquid, connection orientation, pressure rating, and tag data must be checked against the physical unit because configured suffixes and legacy option codes can vary by production date
Construction
Metering tube material
Borosilicate glass
Float material
316 stainless steel for the Model 1358 float options listed in Brooks documentation
End fitting material options
Chrome plated brass or 316 stainless steel, depending on configured code
Window material
Scratch-resistant, UV-stabilized polycarbonate
Connections
Standard connection context
Brooks Model 1358 documentation lists horizontal female 3/8 inch NPT threaded adapters as standard, with additional process-connection options in the model code
Installation
Mounting position
Install within 6 degrees of true vertical with the inlet connection at the bottom end fitting
Safety
Glass tube precautions
Keep the protective sleeve and windows secured, avoid pressure and flow surges, do not exceed pressure and temperature limits, and do not service while pressurized
Observed configuration
Listing context
External distributor and stored auction evidence identify this exact code with 1.5-15 SCFM and 3/8 inch NPT context; this is observed configured-unit evidence, not a model-wide Brooks specification
Applications
Application domain
Local indication of gas or liquid flow in low-flow rotameter service where Model 1358 construction and accuracy are appropriate
