Section 1 Introduction
1-4 Optional Accessories
Needle valves and flow controllers may be externally piped into the inlet or
outlet side of the instrument. Needle valves can be supplied up to size 12
1-1/2" maximum 10000 l/hr / 46 gpm water equivalent. Needle valves and
flow controllers will be supplied separately with the flanged meter.

1-5-1 Transmitter with or without Alarms, Display and Pulse Output
Design Features
A 2-wire, loop-powered device for ease of wiring and installation
• 4-20 mA analog output for flowrate, with Bell-202 modulated HART
communication channel
• User selectable 0% and 100% analog output ranges with optional
smoothing
• Flexible (mix & match) units of measure for flowrates, totals,
temperatures, densities, etc.
• Two flow totalizers: Resettable and inventory totalization
• User configurable, scaleable pulse output for various engineering units
• Comprehensive alarms for both process flow and internal diagnostic
checks
• Easily configured and compatible with other plant equipment
Description
The transmitter (with or without the alarms, display and pulse output)
is a compact microprocessor device designed to interface directly
with the Model MT3809.
The transmitter is HART-programmable for numerous variables such as
flow rate, totalization, calibration factors, and high-low alarm parameters. It
is programmable with easy-to-use hand held configurators. Prior to
shipment, commonly used default values are programmed by Brooks to
ensure ease of operation and quick startup. However, parameters may be
reprogrammed by the user if needed flow rate information may be viewed
locally at the meter scale, LCD display or displayed remotely.
