Brooks Instrument Sho-Rate Model 1358 Variable-Area Flowmeter
About this part
1358F1A2FC4B1BC is a configured Brooks Instrument Sho-Rate Model 1358 glass tube variable-area flowmeter identifier. Official Brooks 1358 documentation identifies the 1358F base as a Sho-Rate "50", Size 8 rotameter and its model-code table supports decoding the configuration through the 1358F1A2FC4B1 portion: R-8M-75-1 tube, 8-RV-8 stainless steel float, right-side aluminum detachable scale, special standard-accuracy scale inscription, Viton packing/O-rings, 3/8 inch NPT locknut connection with 316 stainless steel fittings/adapters, stainless steel inlet needle valve, and back/back port orientation. The trailing BC suffix is part of the exact observed identifier, but it is not defined by the current Brooks 1358 accessory table; confirm the physical label and scale before replacement or process use
Configurations vary. Verify the exact unit before choosing a replacement.

code-table decode limit
Current official Brooks 1358 model-code documentation decodes 1358F1A2FC4B1 through connection orientation; the final BC suffix is not defined in the current accessory table and should be checked against the physical unit or Brooks order records
Function
Measuring principle
Variable-area flow indication using a tapered borosilicate glass metering tube and float
Performance
Standard accuracy
Brooks Model 1358 documentation lists standard accuracy as +/-10% of full scale
Repeatability
Brooks Model 1358 documentation 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
A - 8-RV-8, 316 stainless steel
Tube packing and O-ring code
C - Viton tube packing and Viton O-ring
Configured-unit rule
Physical label, scale markings, and port orientation should be checked before replacement because the Brooks PDFs are model-code and family documents, not a serialized build sheet or calibration certificate for this individual meter
Flow
Official capacity-table context
Brooks Model 1358 capacity tables associate the 8-RV-8 float with 0.8 gpm water maximum flow and 3.4 scfm air maximum flow at stated reference conditions; special scales may be marked differently for a configured unit
Scale
Scale type code
2 - aluminum detachable scale mounted to right side plate
Scale inscription code
F - special inscription, standard 10% accuracy
Connections
Fitting and adapter code
4 - threaded 3/8 inch NPT with locknut connection, 316 stainless steel fitting and adapter
Connection orientation code
1 - inlet port back, outlet port back
Valve
Valve configuration code
B - standard stainless steel needle valve on inlet
Accessories
Accessory suffix
BC appears in the exact observed identifier but is not decoded by the current Brooks 1358 accessory table
Construction
Metering tube material
Borosilicate glass
Window and sleeve context
Brooks Model 1358 documentation lists scratch-resistant UV-stabilized polycarbonate window components and a UV-stabilized polycarbonate protective tube sleeve
Installation
Mounting position
Install within 6 degrees of true vertical with the inlet connection at the bottom end fitting
Observed configuration
Stored listing context
Stored Sonisys auction records for this exact identifier describe an 11.7-117 SLPM range; use this only as observed configured-unit evidence alongside the official code-table decode
Applications
Application domain
Local indication or needle-valve control of low-flow gas or liquid service where the configured Model 1358 materials, pressure/temperature rating, and accuracy are appropriate
