1350GAL3AAJU5ARA is a configured Brooks Instrument Sho-Rate 1350G glass tube variable-area flowmeter. Official Brooks 1350G/1355G documentation identifies the 1350G as a 65 mm Sho-Rate flow indicator and its model-code table decodes this configuration as a 316 stainless steel end-block unit with an R-6-65-A G tube, glass float custom-decal scale, Buna packing and O-ring materials, 316 stainless steel 1/4 in NPT end fittings, a medium-flow 316 stainless steel Cartridge III valve, outlet/back-back valve orientation, no alarms, stainless steel tag option, and no listed certification option. Exact scale markings and calibrated range should still be verified from the physical unit label and scale
Configurations vary. Verify the exact unit before choosing a replacement.
