Brooks Instrument Sho-Rate 1355E Variable Area Flowmeter
About this part
1355EE2BCFG5LM 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 an E-series 1355E meter with an R-2-15-C tube, stainless steel float, special single scale, Viton tube packing and O-rings, 316 stainless steel threaded 1/8 in. NPT fittings with locknuts, a 316 stainless steel high-flow standard valve on the outlet, and stainless side-plate and spring-float-stop accessory selections. Stored Sonisys auction records identify this exact code as a Brooks Sho-Rate 1355E flow meter and include 200 psi / 250 F context; exact installed scale range and service fluid should still be verified from the physical scale and label
Configurations vary. Verify the exact unit before choosing a replacement.
