1.10 Design of Rosemount™ 3410 series meter
Rosemount 3410 Series Gas Ultrasonic Flow Meters are designed to
accurately measure products in applications where reliable performance is
critical, by measuring the difference in signal transit time with and against
the flow across one or more measurement path(s). A signal transmitted in
the flow direction travels faster than one transmitted against the flow
direction. Each measurement path is defined by a transducer pair in which
each transducer alternately acts as transmitter and receiver. The meter uses
transit time measurements and transducer location information to calculate
the mean velocity.
The 3418 combines the power of two interlocked 4-path British Gas design
meters in one flowmeter body. The second set of chords is the mirror image
of the first, which allows the meter to cancel out the effects of swirl and
cross flow. The meter offers bidirectional measurement and superior lowflow capabilities, without the compromises associated with conventional
technologies.

All Rosemount ultrasonic flow meter's U.L. safety listing is accomplished
through the combination of an explosion-proof transmitter electronics
enclosure that houses the CPU module, Power Supply board, I.S. Barrier
board, Backplane board and optional LCD Display board.
Note
The optional LCD Display requires firmware v1.04 or later and Uboot version,
January 31, 2013.
The Base Electronics Enclosure that houses the Acquisition Module.
Intrinsically safe transducers and cable assemblies are designed for Class 1,
Division1, Groups C and D areas without need of further protection when
installed in accordance with the field wiring diagram (refer to Rosemount

WARNING
CONTENTS MAY BE UNDER PRESSURE
When the meter is under pressure, DO NOT attempt to remove or adjust the
transducer holder of the T-Slot transducer assembly, or loosen the screws
holding the T-200 transducer assembly.
Attempting to do so could release pressurized gases, resulting in serious
injury or equipment damage.
Installation manual 15
Installation manual April 2022
WARNING
CONTENTS MAY BE HAZARDOUS
The meter must be fully depressurized and drained before attempting to
remove the T-200 transducer assembly. If gas or fluid begins to leak from the
T-200 transducer stalk assembly, stop immediately and reinstall T-200 stalk
assembly.
Failure to comply could cause serious injury or equipment damage.
A. Transducer holder
CAUTION
ESCAPING GASES OR FLUIDS HAZARD
The purchaser of the meter is responsible for the selection of Rosemount
components/seals and materials compatible with the chemical properties of
gas flow measurement.
Failure to select the suitable meter component/seals may cause escaping
gases or liquids, resulting in injury or equipment damage.
Consult your Emerson Flow sales and service representative to ensure you
purchase the correct components and seals for your application.

WARNING
EXPLOSION OR FIRE HAZARD
Conduit runs must have a sealing fitting within 18 inches (457 mm) of the
enclosure to reduce the risk of an explosion or a fire.
• During operation, keep covers tight.
• During equipment maintenance, disconnect power before opening
transmitter or base electronics. Clean cover joints before replacing.
• DO NOT substitute meter components. Component substituting may
compromise the intrinsic safety.
Failure to comply could result in severe injury to personnel or cause damage
to the equipment.

2 Mechanical installation
2.1 Meter piping, lifting and mounting
Refer to the following sections for piping recommendations, lifting with
hoist rings and slings, mounting in heated or cooled pipelines and safety
warnings and precautions.
CAUTION
SURFACE TEMPERATURE HAZARD
The meter body and piping may be extremely hot or cold.
Wear appropriate personal protective equipment when coming in contact
with the meter.
Failure to comply may result in injury.
WARNING
CUTTING HAZARD
Sharp edges may be present on the transducer retaining ring.
Wear appropriate eye protection equipment when removing or installing
the transducer retaining ring.

CRUSHING HAZARD
Do not remove flange stabilizers.
Attempting to do so could allow the meter to roll, resulting in serious injury
or equipment damage.
A. Flange stabilizers
WARNING
CRUSHING HAZARD
Before installation, do not rest the meter on a slope of greater than 10
degrees. Also ensure the surface is solid so that the flange stabilizers do not
sink into the surface.
Failure to comply could allow the meter to roll, resulting in serious injury or
equipment damage.
CAUTION
ESCAPING GASES OR FLUIDS HAZARD
The purchaser of the meter is responsible for the selection of Rosemount
components/seals and materials compatible with the chemical properties of
