Brooks Instrument 3809E12A1KAA1C1 Variable Area Flow Meter

Brooks Instrument MT3809E12A1KAA1C1 is a metal-tube variable-area flow meter (rotameter) designed for high-temperature and high-pressure service with gas or liquid media. It belongs to Brooks’ MT3809 VA flow meter family, utilizing a calibrated float inside a precision metal tube to yield a direct, scale-ready flow reading without electrical power. This specific configuration specifies a flow range of 1.2–12 standard cubic meters per hour and a 1/2 in NPT process connection for compact installation. The MT3809 series supports gas or liquid media and operates over a wide temperature band from -198°C to 420°C, with enclosure options including IP66, IP67, IP65 and NEMA 4X depending on kit configuration. Optional electronics are available via Brooks’ Smart Meter Manager to interface VA readings with control systems, data acquisition, or SCADA. Designed for challenging process environments, the MT3809 offers a robust solution for industries such as oil and gas, chemical processing, and general industrial instrumentation where a reliable, stand-alone flow indication is required.
