impair the protection provided by the equipment.
• Any substitution of non-authorized parts or repair, other than exchanging the
complete transmitter head or antenna assembly, may jeopardize safety and is
prohibited.
• Unauthorized changes to the product are strictly prohibited as they may
unintentionally and unpredictably alter performance and jeopardize safety.
Unauthorized changes that interfere with the integrity of the welds or flanges,
such as making additional perforations, compromise product integrity and
safety. Equipment ratings and certifications are no longer valid on any products
that have been damaged or modified without the prior written permission of
Emerson Process Management. Any continued use of product that has been
damaged or modified without prior written authorization is at the customer's
sole risk and expense.
Explosions could result in death or serious injury
• Verify that the operating environment of the transmitter is consistent with the
appropriate hazardous locations specifications.
• In an Explosion-proof/Flameproof installation, do not remove the transmitter
cover when power is applied to the unit.
• Before connecting a
make sure the instruments in the loop are installed in accordance with
intrinsically safe or non-incendive field wiring practices.
Electrical shock can result in death or serious injury

PRODUCT RECYCLING/
DISPOSAL
Recycling of equipment and packaging should be taken into consideration
and disposed of in accordance with local and national legislation/regulations.
THEORY OF OPERATIONThe Rosemount 5400M Series Radar Gauge is a smart, two-wire continuous
level transmitter. A 540 0 transmitter is installed at the top of the tank and
emits short microwave pulses towards the product surface in the tank. When
a pulse reaches the surface, part of the energy is reflected back to the
antenna for subsequent processing by the transmitter electronics. The time
difference between the transmitte d and refle cted p ulse is detected by a microprocessor and is converted into a distance, which calculates the level.
The product level is related to the tank height and the measured distance by
the following expression:
Level = Tank Height - Distance.

components.
The Rosemount 5400M Series Radar Gauge is a vailable with a stainless steel
housing containing advanced electronics for signal processing.
The radar electronics produces an electromagnetic pulse that is emitted
through the antenna.
The transmitter head has separate compartments for electronics and
terminals, and can be removed without opening the tank. The head has two
entries for conduit/cable connections.
The tank connection consists of a Tank Seal and a flange (DIN or JIS).

ARCHITECTURE
Figure 2-3. HART system
architecture
The Rosemount 5400M Series Radar Transmitter is loop-powered, and uses
the same two wires for power supply and output signal. The output is a 4-20
mA analog signal superimposed with a digital HART signal.
By using the optional HART T ri-lo op, th e HAR T sign al ca n be converte d up to
three additional 4-20 mA analog signals.
With the HART protocol multidrop configuration is possible. In this case,
communication is restricted to digital, since current is fixed to the 4 mA
minimum value.
The transmitter can be connected to a Rosemount 751 Field Signal Ind ica to r,
or it can be equipped with an integral display.
The transmitter can easily be configured using a PC with the Rosemount
Radar Master software. Rosemount 5400M Series transmitters can also be
configured with the AMS
®
Suite and DeltaV™ software, and other tools that
support Electronic Device Description Language (EDDL) functionality.
For HART communication a minimum load resist ance of 2 50Ω within the loop
is required.

MARINE APPLICATION
CHARACTERISTICS
A calm surface gives better reflection than a turbulent surface. Maximum
measurement range for a Marine application has taken turbulence surface in
consideration and in-tank environment. For pr oducts with higher dielectric
constant and/or lower turbulence surface measuring range can be extended.
Please advice Rosemount Tank Radar AB for details.
Dielectric constantA key parameter for measure ment performance is reflectivity. A high dielectric
constant of the media provides better reflection and enables a longer
measuring range.
FoamRosemount 5400M Series Radar Transmitter measurement in foamy
applications depends on the foam properties; light and airy or dense and
heavy, high or low dielectrics, etc. If the foam is conductive and creamy, the
transmitter may measure the surface of the foam. If the foam is less
conductive, the microwaves may penetrate the foam, and measure the liquid
surface.
Transition ZoneThe measurement accuracy is reduced within the Transition Zone region 6 in.
(150 mm) from the lower end of the antenna. This is normally avoided by
following installation drawings and by choice of gauge socket.

PLACEMENT
CONSIDERATIONS
Before installing a Rosemount 5400M Series Transmitter, consider specific
mounting requirements, vessel, and process characteristics.
The general recommendation in international (ISO) and API measurement
standards for location is to place the transmitter as close to the tan k center on
deck as possible. This location minimizes the uncertainty from trim/list
corrections, as well as avoids excessive liquid turbulence during open sea
operations.
This is especially important for tankers, operating in high sea conditions such
as shuttle tankers, FPSO’s etc. This reduces excessive errors in the trim/list
correction of ullage, minimizes the liquid splashing from the bulkheads and is
of essential importance to achieve an acceptable measure ment.
Locating the transmitter close to the vertical line through the center of gravity
of the tank, also provides the best accuracy for volume calculation.
Free space requirementsWhen deciding the location of the transmitter on deck, the free space
requirement must be considered. The radar beam must pass unobstructed to
the tank bottom. This is the most important requirement in order to get a
trouble-free operation of the transmitter . The ideal free space requirem ents for
the transmitter is best described as a circular cone, centered around the
antenna axis with an angle of 9°. See Figure 3-1 on page -4.
There can be certain exceptions from the ideal free space requirements, for
example when the transmitter is installed close to a bulkhead. Exceptions with
requirements and recommendations are descr ibed later on in this chapter.
All exceptions from the ideal free space requirements mu st be revised and
approved by Rosemount Tank Radar AB before any inst allation arrangement s
are planned.
If there are any hesitations about the location of the transmitter, contact
Rosemount Tank Radar AB.

Pipes Intruding into the
Radar Beam
4
One pipe with a diameter that equals to or is less than 56 mm (2”) can, withou t
restriction, pass through the inner area of the radar beam. Another pipe,
without flanged joints, does not seriously affect the performance and can be
allowed outside a 9° cone centered around the antenna axis. In doubtful
cases contact Rosemount Tank Radar AB for advice.
Location of Heating Coils
Heating coils, should if possible be located outside the radar b eam so that the
radar echo is unaffected within the free space requirements.

outside the radar beam (left).

deflect unwanted radar echo
(right).
The unwanted radar echo can be deflected by inclining the coils with an angle
of at least 4°. When there is an inclined tank bottom, the coils should be
placed as shown in the picture.

inclined tank bottom. The left
tank is an example of how to
place the coils. The right tank is
an example of how NOT to place
the coils.
Rosemount 5400M Series
Coil Supports
In order to minimize the radar echo from the coil supports, they should first of
all never be placed within the radar beam. If that cannot be avoided, they
should be placed on the side that faces away from the radar beam’s center.
The top of the support should also be bevel-edged, or the whole holder tilted,
in order to avoid a reflecting surface towards the radar beam.
