2Transmitter overview
2.1Measurement principle
The Rosemount 5408 is a two-wire transmitter for continuous level measurements using
fast-sweep Frequency Modulated Continuous Wave (FMCW) technology.
The transmitter continuously emits signal sweeps with a constantly varying frequency
towards the product surface. Since the transmitter continuously changes the frequency of
the transmitted signal, there will be a difference in frequency between the transmitted
and the reflected signals (see Figure 2-1).
The frequency of the reflected signal is subtracted from the frequency of the signal
transmitted at that moment, resulting in a low frequency signal which is proportional to
the distance to the product surface. This signal is further processed to obtain fast, reliable,
and highly accurate level measurements.

2.2Process characteristics
2.2.1Dielectric constant
A key parameter for measurement performance is reflectivity. A high dielectric constant of
the media provides better reflection and enables a longer measuring range.
®
2.2.2Foam and turbulence
Foaming liquids or turbulence may cause weak and varying surface echo amplitudes. The
effects of turbulence are usually minor, but in the most challenging conditions, the
10 Reference Manual
Reference ManualTransmitter overview
00809-0100-4408April 2022
transmitter may be mounted in a still pipe. In addition, measurement performance can be
optimized by configuring the appropriate process conditions settings.
Measurement in foamy applications depends largely on the foam properties. When the
foam is light and airy, the actual product level is measured. For heavy and dense foam, the
transmitter may measure the level of the foam’s upper surface.
The Double Surface Handling function allows the user to select if the foam layer or product
surface should be used as output.
Related information
Process conditions
Double surface handling
2.2.3Dust
Dust is often present in solids applications, and even if the non-contacting radar is not
affected by the dust in the vapor space, dust can be sticky and create a layer on the
antenna. If this layer becomes too thick, it may affect the measurement. This is best
managed by using air purging.
2.2.4Solid surface
Solids have some common characteristics which may cause weak and varying surface
reflections. The surface is rarely flat or horizontal, the angle of the sloping surface differs
during filling and emptying, and the dielectric constant of many solids is fairly low. Table
2-1 presents common characteristics of some solids applications.
The parabolic antenna is ideal for applications with weak surface reflections. A larger
diameter concentrates the radar beam and ensures maximum antenna gain. The parabolic
antenna comes with a swivel connection that adjusts for angled tank roofs.

2.3Vessel characteristics
2.3.1In-tank obstructions
The transmitter should be mounted so that objects such as heating coils, ladders, and
agitators are not in the radar signal path. These objects may cause false echoes resulting in
reduced measurement performance. However, the transmitter has built-in functions
designed to reduce the influence from disturbing objects where such objects cannot be
totally avoided.
Vertical and inclined structures cause minimal effect since the radar signal is scattered
rather than directed back to the antenna.
2.3.2Tank shape
The shape of the tank bottom affects the measurement signal when the product surface is
close to the tank bottom. The transmitter has built-in functions which optimize
measurement performance for various bottom shapes.
2.4Application examples
The Rosemount 5408 and 5408:SIS are ideal for level measurements over a broad range of
liquid and solids applications. The transmitters are virtually unaffected by changing
density, temperature, pressure, media dielectric, pH, and viscosity. Non-contacting radar

level is ideal for harsh conditions such as corrosive and sticky media, or when internal tank
obstructions are a limiting factor.
Storage and buffer tanks
The Rosemount 5408 provides accurate and reliable level measurement for both metallic
or non-metallic vessels containing almost any liquid (e.g. oil, gas condensate, water,
chemicals).
Reactors
The Rosemount 5408 is ideal for the most challenging applications, including reactors
where there can be agitation, foaming, and condensation, as well as high temperatures
and pressures.
Blenders and mixers
The Rosemount 5408 can help you withstand the rigors of blenders and mixing tanks. Easy
to install and commission, it is also unaffected by virtually any fluid property change.

Transmitter overviewReference Manual
April 202200809-0100-4408
Open atmospheric applications
The Rosemount 5408 measures reliably in open applications, from short range sumps or
ponds to long range dams.
Still pipe and chamber installations
The Rosemount 5408 is a great choice for level measurement in tanks with small diameter
still pipes. It may also be used in chambers, but guided wave radar is generally the best fit
for these applications. For more information on using the Rosemount 5408 in still pipes
and chambers refer to the Best Practices for Using Radar in Still Pipes and Chambers
Technical Note.
Bulk solids
The Rosemount 5408 is the ideal solution for small- to medium-sized silos with rapid level
changes. The narrow beam avoids internal obstructions while still keeping good level
measurement.

2.6System integration
The 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. The transmitter can be configured for either HART Revision 6 or 7. The HART
Revision can be switched in field.
By using the optional Rosemount 333 HART Tri-Loop™, the digital HART signal can be
converted into 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 combined with the Emerson Wireless 775 THUM™ Adapter to
wirelessly communicate HART data with IEC 62591 (WirelessHART®) technology. In
addition, the transmitter can be connected to a Rosemount 751 Field Signal Indicator, or it
can be equipped with an integral display.

3.3.2Free space requirements
If the transmitter is mounted close to a wall or other tank obstruction such as heating coils
and ladders, noise might appear in the measurement signal. See Table 3-1 for
recommended clearance.
For easy access to the transmitter, mount it with sufficient service space (see Table 3-2).

DescriptionDistance
Service space width (A)20 in. (500 mm)
Service space height (B)24 in. (600 mm)
3.3.3Antenna size
Choose as large antenna diameter as possible. A larger antenna diameter concentrates the
radar beam and ensures maximum antenna gain. Increased antenna gain permits greater
margin for weak surface echoes.
In addition, a larger antenna diameter results in a smaller beam angle and thereby, less
interference from any internal structures in the tank.
3.3.4Antenna inclination
Ensure the antenna is aligned perpendicular to the product surface (see Figure 3-4). The
parabolic antenna comes with a swivel connection that adjusts for angled tank roofs.
Note that if the surface echo is weak in solids applications, then a small inclination of the
parabolic antenna toward the surface slope may improve the performance.

3.3.5Non-metallic tanks
Nearby objects outside the tank may cause disturbing radar echoes. Wherever possible,
the transmitter should be positioned so that objects close to the tank are kept outside the
signal beam.
3.3.6Beam width and beam angle
The transmitter should be mounted with as few internal structures as possible within the
signal beam. Refer to Table 3-3 for beam angle and Table 3-4 for beam width at different
distances.
To allow the microwaves to propagate undisturbed, the nozzle dimensions should be kept
within the specified limits as given in Table 3-5, Table 3-6, and Table 3-7.
Nozzle requirements for cone antenna
For best performance, the cone antenna should extend at least 0.4 in. (10 mm) below the
nozzle. If required, use the extended cone antenna versions (option code S1 or S2).
However, the antenna can be recessed in smooth nozzles up to 4 ft. (1.2 m). Note that if
the inside of the nozzle has irregularities (e.g. due to bad welding, rust, or deposit), then
use the extend cone antenna.

4.1Safety messages
Instructions and procedures in this section may require special precautions to ensure the
safety of the personnel performing the operations. Information that potentially raises
safety issues is indicated by a warning symbol (). Refer to the following safety messages
before performing an operation preceded by this symbol.
WARNING
Failure to follow safe installation and servicing guidelines could result in death or
serious injury.
Ensure the transmitter is installed by qualified personnel and in accordance with applicable
code of practice.
Use the equipment only as specified in this manual. Failure to do so may impair the
protection provided by the equipment.
For installations in hazardous locations, the transmitter must be installed according to the
Rosemount 5408 and 5408:SIS Product Certifications document and System Control
Drawing (D7000002-885).
WARNING
Explosions could result in death or serious injury.
Verify that the operating atmosphere of the transmitter is consistent with the appropriate
hazardous locations certifications.
Before connecting a handheld communicator in an explosive atmosphere, ensure the
instruments are installed in accordance with intrinsically safe or non-incendive field wiring
practices.
In Explosion-proof/Flameproof and Non-Incendive/Type n installations, do not remove the
transmitter covers when power is applied to the unit.
Both transmitter covers must be fully engaged to meet Explosion-proof/Flameproof
requirements.
WARNING
Electrical shock could cause death or serious injury.
In Explosion-proof/Flameproof and Non-Incendive/Type n installations, avoid contact with
the leads and terminals. High voltage that may be present on leads can cause electrical
shock.
Ensure the mains power to the transmitter is off and the lines to any other external power
source are disconnected or not powered while wiring the transmitter.

6.5Smart echo level test
The function allows you to test the behavior of the transmitter in a real tank environment
without raising the level. During the test, a virtual surface echo is superimposed onto the
radar signal, and the transmitter will output a level corresponding to the echo position.
The test verifies the integrity of the signal processing, and can be used to test the alarm
limits in the host system, output of the transmitter, and transmitter configuration (for
example the upper/lower range values).
