2.1 Measurement principle
The Rosemount™5408 and 5408:SIS are two-wire transmitters for continuous level
measurement of a broad range of liquids and slurries. It uses two-wire 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.
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.

2.2 Process characteristics
2.2.1 Dielectric 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.
In addition to the dielectric constant, the measuring range depends on the microwave
frequency, antenna size, and the process conditions (see “Measuring range” on page 121).
2.2.2 Foam 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
transmitter may be mounted in a still pipe. In addition, measurement performance can be
optimized by enabling the appropriate process conditions parameters, see “Process
conditions” on page 171.
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.
2.2.3 Condensation
Generally, the radar signal is unaffected by condensation and low pressure steam. However,
heavy condensation can effect the measurement. In such applications, air purging may be
required to prevent clogging of the antenna.
In high temperature applications, it is recommended to insulate the tank nozzle. Insulation
prevents the nozzle from becoming a cold spot, and thus reduces the amount of water build
up and condensation on the antenna.
If the temperature in the tank is much higher than the ambient temperature (i.e. tank is
heated and located in a cold area), it might be necessary to heat trace the nozzle in addition
to the insulation.
2.3 Vessel characteristics
2.3.1 In-tank obstructions
The transmitter should be mounted so that objects such as heating coils, ladders, agitators
and so on 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.

2.3.2 Tank 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.
2.4 Application examples
The Rosemount 5408 and 5408:SIS are ideal for level measurements on a broad range of
liquids and slurries. The transmitter is 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 storage or
buffer tanks for almost any liquid, e.g. oil, gas condensate, water, chemicals, etc.
Demanding environments
The Rosemount 5408 is a very suitable choice for the most challenging applications, such as
reactors with varying process conditions and product turbulence created by agitators.

Reactors and mixing tanks
Rosemount 5408 can help you withstand the rigors of reactor and mixing tanks. Easy to
install and commission, it is also unaffected by virtually any fluid property change.
Still pipe and chamber installations
The Rosemount 5408 is an excellent choice for level measurement in tanks with still pipes. It
may also be used in chambers, but guided wave radar is generally the best fit for these
applications. See “Installation in still pipe/chamber” on page 16 for installation guidelines.

2.6 System 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 (default) or 7 (option code HR7).
The HART Revision can be switched in field.
By using the optional Rosemount 333 HART Tri-Loop™, the HART signal can be converted 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 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 LCD display.
The transmitter can easily be configured by using a PC with the Rosemount Radar Master
software (running in Instrument Inspector™), a Field Communicator, the AMS™Suite:
Intelligent Device Manager, or any other Device Descriptor (DD) or Field Device Integration
(FDI) compatible host system.
The Rosemount 5408 and 5408:SIS are compliant to the NAMUR NE 107 Field Diagnostics
for standardized device diagnostic information.
