Design Features
• Foundation
TM
Fieldbus digital communication network interface
• Ease of wiring and installation with a single 2-wire bus connection
• Powered over 2-wire Foundation
TM
Fieldbus connection
• Flexible (mix & match) units of measure for owrates, totals,
temperatures, densities, etc.
• Two ow totalizers: Resettable and inventory totalization
• User congurable, scalable pulse output for various engineering units

Description
The Foundation
TM
Fieldbus transmitter is a compact microprocessor device
designed to interface directly with the Model MT3809.
The transmitter communicates over the 2-wire network per the
international Foundation
TM
Fieldbus standard for access to numerous
variables such as ow rate, totalization, calibration factors, and high-low
alarm parameters.
