Brooks Instrument Sho-Rate 1355E Variable Area Flowmeter
About this part
1355EE2BAAA1A is a configured Brooks Instrument Sho-Rate 150 / Model 1355E glass tube variable-area flowmeter. Official Brooks 1350E/1355E documentation identifies 1355E as the 150 mm Sho-Rate family and provides the model-code table used to decode this configured code as a 1355E meter with an R-2-15-C tube, stainless steel float, special single scale, Buna tube packing and Buna O-rings, brass threaded 1/8 in. NPT fittings with locknuts, a valve plug, inlet valve cavity location, and no accessory code. Stored Sonisys auction records and live surplus listings identify this exact code as a Brooks flow meter; the installed special scale fluid and range should still be verified from the physical scale and label
Configurations vary. Verify the exact unit before choosing a replacement.

Performance
1355 Series accuracy
Brooks 1350E/1355E documentation lists 1355 Series standard accuracy as +/-5% full scale
Repeatability
Brooks 1350E/1355E documentation lists repeatability as 0.5% full scale
Pressure and temperature
Family pressure and temperature rating
Brooks 1350E/1355E documentation lists 200 psig from 33 deg F to 250 deg F / 1 deg C to 121 deg C, and 170 psig over the same temperature range when supplied under CRN certification

Accessories
Accessory code
Code A indicates no accessory selection
Installation
Orientation
Install within 6 degrees of true vertical with inlet connection at the bottom end fitting
Configuration
Configured-unit rule
Special scale fluid, direct-reading range, calibration basis, condition of the glass tube and float, seals, connection condition, and process suitability must be verified from the physical unit
Observed variants
Stored auction context
Stored Sonisys title evidence and live surplus listing evidence identify this exact configured code as a Brooks / Brooks Instrument flow meter
Applications
Application domain
Low-flow gas and liquid indication, purge flow service, panel-mounted rotameter applications, and configured flow-control assemblies where the unit's materials and calibration match the process
