Brooks Instrument Sho-Rate 1350E Variable Area Flowmeter
About this part
1350EZ122 is a configured Brooks Instrument Sho-Rate 50 / Model 1350E glass tube variable-area flowmeter identifier. Official Brooks 1350E/1355E documentation provides the family-level flowmeter construction, accuracy, pressure/temperature, connection, scale, valve, controller, installation, and maintenance context. The Z122 suffix and observed 209-134 or 213-167 material-number context should be treated as configured-unit or customer/OEM evidence unless verified from the physical unit label, scale markings, or official build documentation
Configurations vary. Verify the exact unit before choosing a replacement.
