Brooks Instrument Metal Tube Variable Area Flowmeter
About this part
MT3809G is a Brooks Instrument MT3809G Series all-metal variable area flowmeter model used for industrial gas, liquid, and steam flow measurement depending on configuration. Official Brooks documentation supports the metal-tube variable-area identity, optional indicators, transmitters, alarms, materials, connections, hazardous-area options, and high-temperature/high-pressure application context, but exact flow range, process connection, materials, electronics, pressure rating, temperature limits, and approvals must be verified from the configured model code and nameplate
Configurations vary. Verify the exact unit before choosing a replacement.
