Brooks Instrument Sho-Rate 1350E Variable Area Flowmeter
About this part
1350ELB6LFE1A is a configured Brooks Instrument Sho-Rate 50 / Model 1350E glass tube variable-area flowmeter identifier. Official Brooks 1350E/1355E documentation provides the family-level construction, accuracy, pressure/temperature, scale, connection, valve, controller, and installation context. Stored Sonisys auction records identify this exact code as a Brooks Sho-Rate variable-area flowmeter, and separate surplus-sale evidence observes a 0-.95 SCFH purge-meter configuration for this configured code; exact scale, service fluid, tube and float code, valve/controller option, materials, connection, and certification should be verified from the physical unit label and scale markings
Configurations vary. Verify the exact unit before choosing a replacement.

Chrome plated brass, black anodized aluminum, and 316 stainless steel
Connections
Standard connection
Horizontal female 1/8 inch NPT threaded adapters with locknuts for front panel mounting
Optional connection context
Brooks 1350E/1355E documentation lists optional compression, 1/4 inch female NPT, hose, VCR, and Rc connection configurations
Controls
Integral control options
Standard integral flow control valve, NRS integral flow control valve, and 8800/8900 integral flow controller configurations are supported by the family documentation
Installation
Orientation
Install within 6 degrees of true vertical with inlet connection at the bottom end fitting
Configuration
Configured-unit rule
Tube, float, direct-reading scale, valve or controller option, end-block material, seal material, process connection, calibrated fluid/range, and pressure certification must be verified from the unit label and scale markings
Observed variants
Stored auction context
Stored Sonisys auction evidence identifies this exact code as a Brooks Sho-Rate variable-area flowmeter
Surplus-sale flow context
Surplus-sale evidence for this exact configured code observes Brooks purge-meter wording with a 0-.95 SCFH range; this is observed configuration context, not an official model-wide specification
Applications
Application domain
Low-flow gas and liquid indication, purge flow service, panel-mounted rotameter applications, and configured flow-control assemblies
