Brooks Instrument MT3809G Metal Tube Variable Area Flowmeter
About this part
3809G is a Brooks Instrument metal tube variable-area flowmeter identifier observed in Sonisys auction history and exact listing records records. Exact configured-code examples include 3809GAD10DACB1A00000 and 3809GHD07BBBB1A00000. Brooks MT3809/MT3809G family documentation supplies the technical baseline, while final connection, pressure, temperature, electronics, scale, and material details should be confirmed from the specific unit label
Configurations vary. Verify the exact unit before choosing a replacement.
