Brooks Instrument Sho-Rate 1355E Variable Area Flowmeter
About this part
1355EG2ECGD5A 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-6-15-A tube, tantalum float, special single scale, Viton tube packing and O-rings, brass 1/4 in. NPT fittings, a brass high-flow standard valve on the outlet, and no accessory selection. Stored Sonisys auction records and surplus and listing evidence identify this exact code with observed 0.39-3.9 m3/h and 1/4 in. NPT context; the installed scale fluid, calibration basis, and service suitability should still be verified from the physical scale and label
Configurations vary. Verify the exact unit before choosing a replacement.

Function
Measuring principle
Variable area flow indication using a tapered glass metering tube and metering float
Scale
1355 series scale length
150 mm nominal
Scale option decoded from code G2E
Special single scale with standard 1355 accuracy context; exact fluid, units, calibration basis, and range are unit-specific and must be read from the installed scale
Flow path
Tube and float decoded from code G2E
R-6-15-A tube with tantalum float
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
Construction
Metering tube material
Borosilicate glass
Packing and seals decoded from code C
Viton tube packing with Viton O-rings
Fitting and connection decoded from code G
Brass 1/4 in. NPT fittings; Brooks model-code table marks this as the standard fitting selection when used with a flow controller
Controls
Valve decoded from code D
Standard brass high-flow valve
Valve location decoded from code 5
Outlet valve cavity location with in-back / out-back standard connection orientation
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, valve condition, seals, connection condition, and process suitability must be verified from the physical unit
Observed variants
Stored listing flow and connection context
Stored Sonisys auction evidence and surplus and listing evidence identify this exact configured code with 0.39-3.9 m3/h and 1/4 in. NPT wording
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
