Brooks Instrument Sho-Rate 1350E Variable Area Flowmeter
About this part
1350ELJ1ALA1A is a configured Brooks Instrument Sho-Rate 50 / Model 1350E glass tube variable-area flowmeter. Official Brooks 1350E/1355E documentation provides the family-level flowmeter construction, accuracy, repeatability, pressure/temperature, scale, connection, control-option, and installation context. Stored exact-code auction evidence identifies this item as a Brooks 1350ELJ1ALA1A flow meter, but exact tube, float, scale, calibrated fluid, valve or controller option, end-block material, seal material, connection, and service limits should be verified from the physical unit label and scale markings
Configurations vary. Verify the exact unit before choosing a replacement.
