Models MT3809G & MT3810G
1 Introduction
The Brooks
®
Models MT3809 and MT3810 are rugged, all metal
owmeters offering reliable operation based on the variable area principle.
The Model MT3809 is constructed with stainless steel components for
measuring a variety of liquid and gas applications while the Model MT3809
ETFE utilizes an E/TFE lining for aggressive liquid and gas applications.
Flow rate indication is provided by means of magnetic coupling where a
magnet, encapsulated in the oat, is coupled to a rotatable magnet located
in the rear of the indicator, thus turning the dial indicator mounted on the
meter.
Optional accessories available includes transmitter with 4-20 mA
analog output with HART

communications with or without congurable alarms and pulse output
for totalization. Also available are front adjustable inductive alarms, high
temperature or stainless steel indicator housings, valves, ow controllers
and certications.
1-1 Design Features
The Brooks Model MT3809 has been the “go to” meter for several years
and the choice of Engineering Contractor customers (EPC). Brooks is
proud to raise the performance of the standard meter by adding these new
features and options:
• Transmitter with 4-20mA/HART-7, or transmitter with Foundation
TM
Fieldbus Communications
• Local Operator Interface with LCD display without removing the cover
which means changes can be made even in hazardous areas
• 316SS ameproof housing
• The broadest range of operating temperatures in the industry, the perfect
meter for even more applications
• Even lower ow rates with the current lay lengths which means one
meter style can be used for very low to high ow rates
• The new meter is designed to ASME B31.3 and gasket sealing surface is
per ASME a rugged design that does not require special gaskets at
installation
• Weldneck anges are standard which means full penetration welds that
can easily be tested for integrity
• Mechanical and alarm design that meets SIL 2 requirements
