Rosemount 3300 and 5300 Series
Guided Wave Radar Application Guidelines
INTRODUCTION
This document is a guideline for Guided Wave Radar
(GWR) applications. Besides providing information
on application advantages, product features, different
types of applications, and probe styles, it also
compares the Rosemount 5300 and 3300 Series
GWRs to assist with radar device selection for
optimal performance.
ROSEMOUNT GUIDED WAVE RADAR
PRODUCT FEATURES
There are two Guided Wave Radar products offered
by Rosemount: the 3300 and the 5300 Series.
Common Features
The Rosemount 3300 Series and Rosemount 5300
Series are multivariable and can measure both level
and interface, with a dual compartment head to
protect electronics from moisture. The electronics
housing can be rotated 360° and in most cases
separated from an installed probe without opening
the tank. Both provide application flexibility and are
available with a full range of probe styles to meet
application requirements. The configuration tools
have installation wizards with waveform plots to
provide easy and powerful configuration and service.
Rosemount 5300 Series superior
performance
•
Handles even the most challenging
applications reliably, including process
vessels, control and safety, extreme
temperature and pressure
•
Microwave innovations as Direct Switch
Technology allow use over longer ranges, with
lower dielectrics and higher accuracy, even
with a single probe
•
Enhanced configuration and diagnostic
information through RadarMaster,
EDDL-based and DTM-based user interface
•
Probe end projection function provides reliable
measurements in applications with low signal
strength
Example of a GWR application.

•
Can measure through most foams
•
Measures interface applications
•
Measures solids, powders, and granules
•

Rosemount 3300 and 5300 Series
APPLICATIONS
Solid applications
Industrial level measurements
The Rosemount 5303 transmitter measures solids
with dielectric constants as low as 1.4 and a
measuring range up to 160 ft. (50 m). Applications
include powders and granules, silicon, plastic pellets,
cement, fly ash, corn, and many more.
Providing accurate and reliable measurement under
process variations and with the ability to handle
turbulence, vapors, coating, moisture, dust, foam and
geometrically difficult vessels, GWR is a popular
alternative for many applications.
•
It is virtually unaffected by dust, moisture,
density changes, and temperature
•
The shape of the material cone is not critical
Liquefied gases and refrigerants
Guided Wave Radar can handle heavy vapors, and it
works well in low dielectric, turbulent applications.
This makes it a good choice for liquefied gases
including LNG, LPG, anhydrous ammonia, and
refrigerants.
Easy replacement of mechanical devices
Guided Wave Radar is an ideal, low maintenance
replacement for displacers, because it has no
moving parts and is unaffected by density changes.
The use of a single lead probe further ensures
minimal maintenance since it is more tolerant of
material coating. Guided Wave Radar is available
with flanges that can match the proprietary cage
flanges or major displacer manufacturers. A robust
high pressure and temperature probe solution for the
Rosemount 5300 Series is also available for these
installations.

Rosemount 3300 and 5300 Series
Replacement of capacitance probes
Guided Wave Radar is an excellent replacement for
capacitance probes since it requires no calibration
and can handle heavy coating. It has a long-lasting
microwave electronics that provides extended
lifetime compared to capacitance probes.
From this
•
The 5300 Series HTHP coaxial probes’
minimum upper layer thickness is 8 in. (20 cm),
and with all other probes 5 in. (12.5 cm)
•
The maximum thickness of the upper layer
depends on the dielectric, probe type and
transmitter
•
Target applications: low upper layer dielectric
(< 3), high lower layer dielectric (>20)
to this...in minutes
Level and interface measurements
Guided wave radar measures both the level and
interface level in separators, and settling and
condensate tanks. The cost for wiring and installation
is reduced because there is one tank penetration and
a single pair of wires. There are some basic
conditions which must be met in interface
measurements:
•
The lower dielectric fluid must be on top
•
The two liquids must have a dielectric
difference of at least 6
•
The upper layer dielectric must be known
(in-field determination is possible)
Demanding environments
The Rosemount 5300 Series handles low reflectivity,
extreme temperatures and pressures, heavy product
coating and saturated steam, making it a reliable
alternative for applications such as distillation
columns, feed-water tanks, and liquefied gases.

COMPARE AND SELECT ROSEMOUNT
GUIDED WAVE RADARS
Both the 3300 and 5300 handles most liquid storage
and monitoring applications. However the 5300 with
its superior performance handles even the most
challenging applications reliably, including process
vessels, control and safety. The application
conditions described here are where the 5300 is the
right choice.
Low Dielectrics with Single Probe
Both level and interface measurements can be
handled with a single lead probe in sticky fluids
(e.g. crude oil, waxy oil), which would leave deposits
on twin lead spacers. Probe End Projection provides
a backup function for challenging applications such
as plastic pellets and boiling hydrocarbons.

Extended Measurement Range
High dielectric materials, such as water based
liquids, solids, ammonia, in vessels up to 165 ft
(50 m).
Low dielectric (1.4) materials, such as liquefied
gas, oil and solids, in vessels up to 82 ft (25 m).
Extreme temperatures and pressures
The Rosemount 5300 Series have heavy-duty probe
options with multiple layers of protection to meet
applications from boilers to cryogenics.

High pressure saturated steam
Safety applications
The Dynamic Vapor Compensation option
dynamically compensates for changes in the vapor
space dielectric, minimizing accuracy errors
associated with varying pressure and / or
temperature.
The Rosemount 5300 Series is Safety Integrated
System suitable.
Disturbing electromagnetic interface
FOUNDATION™ fieldbus
The Rosemount 5300 Series is available with
FOUNDATION™ fieldbus.
The Smart Galvanic Interface and enhanced
transient protection design result in a more stable
microwave performance. This improves the EMI
performance and provides a more robust, safe
measurement with minimized effects from outside
disturbances.

PROBE STYLES
There are five different probe styles for Rosemount
GWRs. The single lead is the preferred choice for
most applications. With the 5300 superior
performance it is possible to use single probes in
more applications. This means lowered costs, less
maintenance, and reduced inventory. The following
guidelines should be used to choose the appropriate
probe for the Rosemount GWRs.
Common Uses for Single Rigid and
Flexible Probes
•
Only option for powders and granules
•
Can be used in sticky and viscous media
•
Is the preferred choice for bypass chambers
Common Uses for Coaxial Probes
•
Acts as a mini stilling well, isolating the probe
from external conditions and obstacles
•
In low dielectric and high turbulent applications
•
Where foam requires isolation from liquid
surface
•
Where there is contact with a metallic object
•
Where the probe may contact inlet fluid flow or
internal tank structures
Avoid using with sticky, viscous, coating media and in
submerged applications.
Avoid using with restrictive nozzles or when the
probe could come in contact with metallic objects in
the vessel.
Common Uses for Twin Rigid and
Flexible Probes
•
Where top-of-foam measurement is desired
•
If the coaxial probe cannot be used
•
If guidelines recommend outside installation
and/or if the dielectric is too low for a single
probe
Avoid using with media that coats and where the
probe may contact walls or obstacles.
