Measurement principle
The level of the liquid (or solid) is measured
by radar signals transmitted from the antenna
at the tank top. After the radar signal is
reflected by the liquid surface the echo is
picked up by the antenna. As the signal is
varying in frequency the echo has a slightly
different frequency compared to the signal
transmitted at that moment. The difference in
frequency is proportional to the distance to the
liquid, and can be accurately calculated. This
method is called FMCW (Frequency Modula-
ted Continuous Wave) and is used in all high
performance radar gauges.
Saab TankRadar®Pro uses the 10 GHz fre-
quency band to get optimum balance between
beam width and sensitivity to antenna con-
tamination.
SaabTankRadar®Pro
with its flexible con-
figuration is suitable for
both stand-alone appli-
cations and large-scale
plant installations with
various tank types.
The FMCW method is
based on a radar sweep
with continuous
changes in frequency.

Technical Description
Applications
Saab TankRadar Pro uses state-of-the art
microwave technology to get highest reliability
and precision. It measures the level of liquids,
slurries as well as many solids. The gauge
operates in a wide range of temperatures,
pressures, vapor gas mixtures and various pro-
cess conditions.
The applications include:
§Chemical & petrochemical storage and
process tanks
§Pharmaceutical reactors
§Food and beverage manufacturing
§Refinery process vessels
§Water and sewage treatment
§Hydroelectric power generation and dams
§Cement,powder,wood chips and other
solid material applications
Applications in process
vessels with agitators
require a radar gauge
withTankRadar Pro’s
high sensitivity and
advanced signal pro-
cessing to separate the
measuring signal from
noise created by dis-
turbances.
Still-pipe or bridle
mounting is recommen-
ded for LPG applica-
tions, where the surface
sometimes is boiling,
and for some extremely
turbulent conditions.
The pipe reduces foam
and turbulence and also
increases surface re-
flection.
The rod antenna is
suitable for small nozzle
openings on tanks with
calm surfaces and short
measuring ranges.
Solid materials, like
cement,often give
extremely small radar
reflections,requiring the
most sensitive antenna,
the 20”parabolic.

Select the right Pro gauge
A TankRadar Pro gauge consists of a Transmit-
ter Head (TH) and a tank connection including
antenna. The TH, as well as the electronics in-
side, is interchangeable without opening the
tank.
The Transmitter Head is available in three
basic versions:
§Lite
Intended for applications in non-hazardous
areas only.Suitable for tanks without
internal structures and agitators,e.g.certain
storage tanks,water,dam applications etc.
The Lite version has only FFT calculations
enabled providing an instrument accuracy
of ±10 mm (±0.4").Echofixer,FHAST and
MET are available as options.
§Standard
For hazardous applications,suitable for
most tanks,also with internal structures,
spherical and bullet tanks.The Standard
version includes the Echofixer software
which more accurately than standard FFT
maps all microwave interference sources.
Standard instrument accuracy is ±10 mm
(±0.4") which can be improved to ±5 mm
(±0.2") using the optional software
modules.
§Gold
Gold is the most advanced version for
difficult applications in tanks with agitators,
heating coils and other disturbances. It
includes the Echofixer software,FHAST™
software for increased accuracy plus
MET™ software for further increased
disturbance echo handling. Instrument
accuracy is ±5 mm (±0.2").
Volume calculation for symmetrical tanks is
included in all versions. Strapping table for
non-symmetrical tanks is available as an op-
tion.
Various options make it possible to optimize the
gauge for different applications:
§Fast FourierTransformation (FFT)
Fast FourierTransformation is a signal
processing technique used to map the
echo structure of the tank.
§Echofixer
A software module that makes it
possible to measure on the surface in
spite of strong disturbance echoes from
mechanical structures such as agitators
and baffles.
§Fast HighAccuracy Signal
Technology (FHAST™)
A module that improves the efficiency of
the signal processing by limiting the
region to be analyzed around the surface.
This results in an improved accuracy of
±5 mm (±0.2").
§Multiple EchoTracking (MET™)
Improves the resolution and accuracy in
echo disturbed regions and close to the
tank bottom.Continuous measurement
on multiple disturbing echoes facilitates
identification of the actual surface echo.
All software options are possible to upgrade in
the field without any changes in electronics.
Upgrades are made by entering a new start
code in the gauge and can be done on a
temporary basis for trial purposes.

Technical Description
Antenna versions
Saab TankRadar®Pro can be equipped with
different antennas to fulfill various
requirements. The antenna is the only part
exposed to the tank atmosphere. The most
common antenna used is the cone type. When
selecting antenna dimension, it is generally
recommended to use as large antenna diame-
ter as possible.
Cone antenna
The cone antenna is suitable for a large range
of applications, both for free propagation and
still-pipe mounted installations. Thanks to the
unique flange clamp solution the existing tank
flange can be used as tank connection. The
gauge can also be delivered with flange
included.
§3", 4", 6" and 8" diameter tank openings.
The 3", 4" and 6" cones can be extended to
fit long tank nozzles.See page 17 for
standard flange options.
§A 1" and a 2" version is available together
with a still-pipe solution.
§Materials exposed to the tank atmosphere:
PTFE or quartz sealing,antenna in steel or
other metals,o-ring inViton or Kalrez.
§Special material such as Hastelloy C 22,
Titanium gr.2,Monel 400 andTantalum.
§Accuracy up to ± 5 mm (0.4") using the
FHAST software option.
§EEx IIC,Zone 0.
§PTB Zone 0 approved.

Parabolic
The parabolic antenna is suitable for both
liquid and solid applications. As it has the
largest diameter it has the most narrow radar
beam and can be used for extremely long
measuring distances.
The parabolic is also the antenna type most
insensitive to contamination. It can be used in
applications with severe antenna condensation
like asphalt and liquid sulphur. Two versions
are available: the very easily installed version
with clamped mounting of flanges with a ø96
mm(3.78in.)holeinflange (low pressures)and
a welded version (high pressures).
§Suitable in all tanks with 450 mm (18") or

Technical Description
RodAntenna
The small dimensions and the fact that only
PTFE is exposed to the tank atmosphere, makes
the rod antenna suitable for small tanks with
hygienic requirements or aggressive chemicals.
It is for 2" and 2 ½" nozzle connections only. If a
larger nozzle is used, a 2" insertion pipe is to be
installed. The Maximum nozzle height is 150
mm(6").
Accuracy is ±10 mm (±0.4") also with the
FHAST software option included. [The Pro
gauges with cone, parabolic and process seal
antennas gets ±5 mm (±0.2") accuracy with the
FHAST software.]

Technical Description
Categories of liquids:
a: Oil,gasoline and other hydrocarbons,
petrochemicals
(dielectric constant, er=1.9-4.0).
b: Alcohols,concentrated acids,organic
solvents,oil/water mixtures and acetone
(er=4.0-10).
c: Conductive liquids,e.g.water based
solutions, dilute acids and alkalis
(er> 10).
For liquids with ersmaller than 1.9 such as
liquefied gases, an 8" or bigger diameter antenna
is recommended if measurement is done with free
propagation.In this case the measuring range in
calm surface tanks is in typical cases 15 m (50 ft).
Measuring range
The diagrams below show how the measuring
range is influenced by the antenna type,
dielectric constant of the liquid (er) and the
process conditions. For optimum performance
the maximum measuring distance should be
kept within the range indicated with darker
colour in the diagrams. Values are valid for
free propagation measurement without still-
pipes (bridles).
To increase the measuring range further in tur-
bulent tanks, a still-pipe can be used. For still-
pipe mounted Pro gauges the typical
measuring range is 35-50 m (115-160 ft) also in
turbulent tanks with liquids having erless than
1.9.

System integration
Level values are transmitted from the gauge as
analog 4-20 mA signals superimposed with
HART®® or digital signals (Profibus DP or
Saab’s Modbus based TRL2 field bus). The
analog outputs are either passive for
connection to powered cables or active provi-
ding signal power for display units etc. Analog
outputs can also be specified to be intrinsically
safe.
When using the digital TRL2 field bus outputs,
up to 12-15 gauges can be connected to each
two-wire field bus, maintaining a high data
updating speed. Each field bus is connected to
a Field Communication Unit (FCU) that hand-
les up to four field buses with data from a
maximum of 32 tanks. Several FCUs can be
installed to handle a large number of tanks.
From the FCU, data can be transmitted on
RS232/485 or TRL2 bus formats to host
computers (DCS, PC or PLC). Pro gauges with
TRL2 bus outputs can also be connected to the
TankMaster operator software providing an
OPC server that can be linked to the plant
network.
Data are displayed on the optional RDU40 dis-
play mounted on the gauge or separately. Via
the display, up to six temperature sensors can
be connected, if the display is mounted
separately. Configuration is easily done on the
4-key display keyboard.
Configuration can also be done on a HART®®
communicator or on a PC using the Windows
based Pro Setup software package. Pro Setup
includes advanced graphics software tools,
including FFT disturbance echo tracking.

Technical Description
Mechanical mounting
The TankRadar Pro gauge is easily carried to
the tank top and mounted on a suitable nozzle
or pipe.
The gauge should be installed as follows:
§Antenna oriented perpendicular to a
horizontal surface.
§The gauge should be mounted with as few
fittings as possible within the beam angle.
§Filling inlets creating turbulence should
preferably be kept at a distance.
§Choose as large antenna diameter as
possible.A larger receiving area
concentrates the radar beam and ensures
maximum antenna gain.Increased antenna
gain offers greater margin for weak surface
echoes.

The flat tank wall can be located within the
antenna beam angle, as long as there is a mini-
mum distance from the gauge to the tank wall,
see picture above.
An extended cone can be used for long
nozzles. The standard length of the extended
cone is 500 mm (20") for 3", 4" or 6" cone
antennas. Longer cones are available on
request.
For best measurement
performance the nozzle
height should be
shorter than the

Pipe installation
Pro gauges with cone antennas can be
mounted in still-pipes. This type of installation
is particularly suitable for applications with
highly turbulent liquids, or liquids with very
low ergiving weak radar reflections, such as
LPG. Suitable still-pipe dimensions are 2", 3",
4" and 6". Also 1" pipes can be used in which
case no antenna at all is used. The 1" and 2"
still-pipe gauges are suitable för clean liquids
only and can be delivered complete with still-
pipe, deflection plate and fittings without any
need for welding. Installation can be made in-
side larger stand-pipes.
Used pipes must generally be clean inside,
without irregularities, rust or excessive holes.
Consult Saab or an authorized distributor for
installation advice.
Electrical connections
The Transmitter Head has two separate
junction boxes. One is for a non-intrinsically
safe primary signal output and power supply
cables. The other is normally used for
intrinsically safe (IS) HART/analog outputs or
optionally for a non-IS analog output.
Outputs can be either active or passive
depending on required options. Cables are
twisted and shielded pairs minimum 0.5 mm2
(AWG 20). Cable entries are ½" NPT for Ex
approved cable glands (CENELEC) or ½" NPT
male conduit fittings (FM/CSA).
