The Rosemount 5400 Level Transmitter is a smart, two-wire continuous level transmitter. A Rosemount
5400 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 transmitted and
reflected pulse is detected by a micro-processor 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

Reactor vessels
The innovative design of the Rosemount 5400 makes it an excellent choice for the
most difficult applications, such as reactor vessels:
Unique circular polarization provides greater mounting flexibility – no tank
wall clearance distance is needed
Direct measurement – independent of most variations in process conditions,
such as density, dielectric, vapor, temperature, and pressure
Can handle turbulent conditions created by agitation, top-filling, or process
reaction
Mounting flexibility
The versatile Rosemount 5400 can be used in mounting configurations other than
standard nozzles:
Fits most existing pipes: 2- to 8-in. (50-200 mm)
Easy to isolate from the process – use a ball-valve
Still-pipes reduce the influence of foam, turbulence, and tank obstructions.
Ball-valves can be used on both still-pipes and nozzles.

The output is a 4-20 mA analog signal superimposed with a digital HART
Modbus
®
signal.
, FOUNDATION™ Fieldbus or
By using the optional 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 connected to a Rosemount 751 Field Signal Indicator, or it can be equipped with
an integral display.
The transmitter can easily be configured using a Field Communicator or a PC with the Rosemount Radar
Master (RRM) software. Rosemount 5400 can also be configured with the AMS™ Suite and DeltaV™
software, and other tools that support Electronic Device Description Language (EDDL) functionality.

2.4Process characteristics
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.
Foam
Rosemount 5400 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.
Turb ul enc e
A calm surface gives better reflection than a turbulent surface. For turbulent applications, the maximum
range of the radar transmitters is reduced. The range depends on the frequency, the antenna size, the
dielectric of the material, and the degree of turbulence. Consult Table 2-2 on page 11 and Table 2-3 on
page 12 for the expected maximum range with the variables listed.
Reference Manual
00809-0100-4026, Rev KB
Temperature/pressure/density and vapor
Temperature, pressure, product density, and vapor generally have no impact on measurements.
Condensation
For applications where heavy condensation and vapors may occur, the low frequency version Rosemount
5401 is recommended.
Tank characteristics
The conditions inside the tank have a significant impact on measurement performance. For more
information see “Vessel characteristics” on page 34.

Solid surface
The surface of solid materials is rarely flat or horizontal. The surface inclination will change as the vessel
fills and empties. There is often a lot of dust during the fill cycle. The dielectric value of many solids is
fairly low. See Table 2-1 on page 9 for common solids characteristics.
For solids applications, the high frequency version Rosemount 5402 with 4 inch cone or parabolic
antenna is available.
