1355B0BB5B2CK is an exact configured Brooks Instrument part identifier associated with the Sho-Rate 1355 low-flow glass tube variable-area flowmeter family. Official Brooks 1350/1355 documentation supports the 1355 family as a 150 mm Sho-Rate glass tube flow indicator with configurable tube, float, scale, end fitting, seal, valve, and accessory options. exact-part surplus listings identify this configured part as a Brooks variable-area flow meter with observed 0-12-1.22 SCC/M scale wording and 1/4 inch NPT context; those listing details should be verified against the physical unit label before use
Configurations vary. Verify the exact unit before choosing a replacement.
Brooks documentation identifies the 1355 family as a 150 mm Sho-Rate flow indicator; current 1355G documentation identifies 1355 as the 150 mm Sho-Rate size 1-6 flow indicator
Flow
Measuring principle
Variable-area flow indication using a tapered borosilicate glass metering tube and metering float
Scale and tube configuration
Brooks 1350/1355 documentation lists multiple tube, float, millimeter scale, linear scale, custom decal, and percent scale configurations; the exact installed scale must be read from the unit
Observed exact-part range context
Exact surplus/listing pages and stored auction records describe this configured part with 0-12-1.22 SCC/M wording; retained as observed listing or label context, not as an official model-wide Brooks rating
Performance
1355 family accuracy context
Brooks legacy 1355E documentation lists Model 1355 standard accuracy as +/-5% full scale, while current 1355G documentation lists 1355G accuracy as +/-3% at reference conditions; verify the configured unit generation and scale before applying an accuracy value
Repeatability context
Brooks 1355E documentation lists repeatability as 0.5% full scale; current 1355G documentation lists repeatability as 0.25% full scale
Pressure and temperature
Series-level pressure/temperature context
Brooks 1350/1355 family documentation lists 200 psig from 33 F to 250 F / 13.8 bar from 1 C to 121 C; verify materials, seals, connections, and configuration before using this limit
Materials
Series-level materials
Brooks documentation lists borosilicate glass metering tubes, glass, 316 stainless steel, sapphire, Carboloy, and tantalum float options, and brass, aluminum, 316 stainless steel, clear polycarbonate, milk-white polycarbonate, and Teflon materials depending on configuration
Seal options
Brooks 1350/1355 documentation lists Buna, Viton, Teflon, EPR/EPM, Kalrez, and related packing or O-ring options depending on model generation and valve configuration
Connections
Connection options
Brooks 1350/1355 documentation lists 1/8 inch NPT, 1/4 inch NPT, compression, hose, Rc, VCR, and related locknut or adapter options depending on configuration
Observed exact-part connection context
Exact surplus/listing pages and stored auction records describe this configured part with 1/4 inch NPT context; verify the installed end fittings on the physical unit
Valve
Valve and controller options
Brooks 1350/1355 documentation lists no-valve, standard needle valve, NRS valve, cartridge valve, and integral flow-controller options depending on model generation and configuration
Installation
Mounting and orientation context
Brooks 1350/1355 documentation describes panel-mount style adapters and installation for low-flow glass tube Sho-Rate flowmeters; installation should follow the matching Brooks manual and the physical unit configuration
Maintenance
Tube and float service
Brooks 1350/1355 documentation describes removable/interchangeable tubes and floats with float stops for service without disconnecting the instrument from process piping, depending on configuration
Applications
Application domain
Low-flow gas or liquid indication and optional flow control in purge, laboratory, analytical, industrial, and OEM applications; exact suitability depends on fluid, scale, pressure, temperature, seals, and materials
