1 Introduction
Saab TankRadar Pro is a powerful radar level gauge suitable for non-contact
level measurements in process tanks, storage tanks and other types of tanks.
It is designed for easy installation and maintenance free operation.
The modular hardware and software design makes it possible to specify a
TankRadar Pro gauge that will meet your requirements now and in the
future.
The TankRadar Pro System
The TankRadar Pro gauge offers a high degree of flexibility. It can be used
as a stand-alone unit, or it can be connected to various control systems.
You can integrate TankRadar Pro in your own Local Area Network (LAN).
By using the Saab TRL/2 Bus interface you can easily connect Pro gauges
to a Saab TankRadar L/2 system.
A specially designed software package, Pro Setup, offers configuration and
service capabilities. It also includes functions for presentation of measure-
ment data.

If HART technology is used you can configure and monitor measurement
data via a hand held communicator or a PC.
For stand-alone systems, or as a complement to a PC or a control system,
you can monitor level data using one or two analog outputs depending on
the particular hardware configuration.
As an option, your TankRadar Pro gauge can be equipped with an easy-to-
use display panel. It offers basically the same functionality as the Pro Setup
software package. Four sturdy softkeys gives you access to configuration
routines, service functions and level monitoring.

Measurement Principle
The Saab TankRadar Pro transmitter sends a microwave signal with a con-
tinuously varying frequency towards the liquid surface. When the reflected
signal returns to the antenna, it is mixed with the outgoing signal.
Since the transmitter continuously changes the frequency of the transmit-
ted signal, there will be a difference in frequency between the transmitted
and the reflected signals.
The gauge mixes the two signals, resulting in a low frequency signal which
is proportional to the distance to the liquid surface. This signal can be
measured very accurately allowing fast, reliable and accurate level measure-
ments.
Saab TankRadar Pro uses an optimum microwave frequency, which reduces
sensitivity to vapour, foam and contamination of the antenna, and keeps
the radar beam narrow in order to minimize influence from walls and
disturbing objects.
Saab TankRadar Pro uses Fast Fourier Transformation (FFT), which is a
well established signal processing technique, to obtain a frequency spec-
trum of all echoes in the tank. From this frequency spectrum the surface
level is extracted. In combination with Saab´s echofixer, FFT allows meas-

urements in tanks with agitators, mixers and other disturbing objects.
Saab´s echofixer provides a technique to adapt measurements to various
situations, by using information from previous measurements.
To further improve measurement accuracy, Saab TankRadar Pro can utilize
the benefits of Saab´s Fast High Accuracy Signal Technique™
(FHAST™).
Multiple Echo Tracking™ (MET™) is another advanced Saab TankRadar
Pro feature, which provides increased resolution in tanks with disturbing
objects. MET™ facilitates the separation of disturbances from the actual
product surface echo.

For optimum measurement performance the TR Pro gauge
should be mounted according to the socket requirements and
the free space requirements illustrated below.
Socket Requirements
In order to allow the microwaves to propagate freely, the socket
dimensions should be kept within the specified limits for differ-
ent antenna sizes.

A hand-held terminal or
a HART modem should
not be connected di-
rectly across an external
power supply. Instead,
it should be connected
across a load resistor of
about 250 Ω.
For Pro gauges with active

Cables
Depending on local requirements, cable
glands or explosion proof conduits must
be used for connection to the non-
intrinsically safe junction box (EEx e).
For the connection to the instrinsically
safe junction box (EEx i) use cable
glands with integral shield connection
for cable diameter 6-12 mm or conduit.
Use shielded instrument cable 0.5 mm2
(AWG 20) for analog outputs and serical
communication.
Safety
The TankRadar Pro enclosure is flame-
proof and may not be opened while the
transmitter is energized and a flammable
atmosphere is present. Saab Tank Con-
trol will not take any responsibility for
local regulations defining conditions
when flameproof enclosures are allowed
to be opened when energized.
Note! Make sure that you do not mix
up intrinsically safe and non-
intrincisally safe wires.
Power Supply
You can use either DC or AC, depend-
ing on what type power supply unit that
is installed in the transmitter. Nominal
supply voltage is:
• 24-48 VDC,
• 100-240 VAC, 50/60 Hz.
See label on the transmitter housing for
information on which supply voltage to
use.
There is no voltage selector in the
electronics compartment since the
transmitter power supply unit automati-
cally adapts to the available voltage
within specified limits.
Grounding
CENELEC
The flameproof enclosure must be
connected to a potential equalizing
network or the tank shell or according to
national code of practice.
This grounding also serves as electrical
safety ground. Additional connection to
the protective ground terminal of termi-
nal X1 in Junction Box EExe is not
recommended except where required
according to national code of practice. A
ground loop with circulating current
may occur. See also the Special Safety
Instruction.
FM
Grounding is accomplished through the
conduit pipes.

4 Pro Setup Software
The Pro Setup software is an easy to use PC program for con-
figuration of the Saab TankRadar Pro transmitter. It is designed
to run under Windows95/NT4.0. It also includes options for
viewing tank data as well as options for advanced service.
It is a simple task to start and configure the TankRadar Pro trans-
mitter. When the gauge is mounted on the tank flange, and the
cables are properly connected you only need to run through a
straightforward configuration procedure to start the transmitter.
In this procedure you will set a few parameters to optimize the
performance of the gauge for your particular application:
Tank dimensions
Type of application.
Analog out: source, range and alarm mode.
Volume calculations (optional).
Tank environment (for the disturbance echo handling).

2 Set the communication address. To set a new address you have to
know the current address or the Unit ID/Long Address (HART) to
establish communication with the gauge. The default address is 0
for HART and 246 for Modbus.
To change the address, do the following:
1 Enter the address that is currently stored in the gauge (the default
address for a new gauge) into the address field.
2 Click the Read button.
Response: the Unit ID/Long Address is displayed.
3 Set the address of your own choice.
4 Click the Store button.
If the transmitter did not respond to the old address do the
following:
1 Enter the Unit ID (Saab Modbus)/Long address (HART) in the
corresponding field. The Unit ID can be found on the label, see
Chapter 3.
2 Enter the desired address in the Address field
3 Click the Store button.
If the transmitter did not respond to the old address, and you
can not find the Unit ID, (for example if the transmitter is lo-
cated far from the configuration PC), do the following:
1 Click the Scan Search button. Pro Setup automatically scans
through a range of possible addresses in order to find connected
devices.
Note! For Modbus devices the scan may be very time consuming if
the default address is still valid. Normally the scan starts at address
0 for HART buses and address 1 for Saab Modbus. You can enter
other start addresses in the Address field in order to reduce the
scanning time.
This function may be useful if you want to find out which addresses
that are currently used by connected devices.
2
Stop the scanning when the correct device is found.
The scan continues until a device is found, or until the search is
stopped by the operator.
3
Enter the address that you want to use for the particular device.
4
Click the Store button.
Now the address is stored in the gauge and will be used for the
communication between the PC and the transmitter.

5 In the Tank Environment and Presentation Standard tab there are
two groups of parameters. In the Environment box mark the check
boxes that correspond to the conditions in your tank:
Rapid level changes
optimizes the transmitter for measurement
conditions where the level changes quickly
due to filling and emptying of the tank.
Turbulent Surface
This parameter may be used if the tank
e.g. contains boiling products causing a
turbulent surface. By setting this param-
eter the performance of the transmitter will
be improved when there are small and
quickly changing amplitudes and levels.
Foam
Setting this parameter optimizes the trans-
mitter for conditions with weak and varying
surface echo amplitudes.
Solid Products
Setting this parameter optimizes the trans-
mitter for products which are not transpar-
ent for radar signals. The effect will be
more reliable handling of false echoes
from beams.
You should not choose more than two options for best performance.
In the Presentation box the following options are available:
Negative values
Set this parameter if you want levels below
as Zero
the reference point at the bottom of the
tank to be displayed as zero. This param-
eter can be used if you have set a C
distance in the tank geometry configura-
tion (see the
Configuration
tab and chapter
Tank Distances
).
Bottom Echo always
Mark this check box if the tank shape
visible if empty tank
allows bottom echoes to be detected. By
setting this parameter the bottom echo will
be treated as a disturbance echo to facili-
tate tracking of weak surface echoes close
to the tank bottom. If this parameter is not
set, searching for a lost surface echo is
Saab TankRadar® Pro Pro Setup
4-13
Edition 2. Ref. No: 306010E
restricted to a region close to the tank
bottom (Related database register:
Full
tank detection area, 1516
).
Do not set this parameter if the bottom
echo is not visible.
Slow Search
This variable controls how to search for
the surface if a surface echo is lost. With
this parameter set the transmitter starts
searching for the surface at the last known
position, and gradually increases the width
of the search region until the surface is
found. If this varaible is not set the trans-
mitter searches through the whole tank.
This parameter may typically be used for
tanks with turbulent conditions.
6 Click the Store button if no further settings are required,
- or -
open the Tank Environment and Presentation Advanced tab to
make further settings:
For some parameters , e.g. Slow Search in the Tank Presentation
group, there is a related holding register which may need to be
changed in order to achieve the best measurement result. For these
parameters the related database registers appear in the bottom
pane of the Advanced tab.
You can edit the register value by simply putting the cursor in the
corresponding input field and enter the desired value.

visible if tank empty
parameters.
Double bounce
Some radar waves are reflected against
possible
the tank roof and back to the surface
before they are detected by the transmit-
ter. Normally, these signals have a low
amplitude and are therefore neglected by
the transmitter. In some rare cases the
amplitude may be strong enough to lead
the transmitter to interpret the double
bounce as the surface echo. By setting the
Double bounce parameter this type of
measurement situation may be improved.
This function should only be used if the
problem of double bounces can not be

Indicates that there are two liquids in the
tank resulting in two reflecting surfaces.
The upper liquid is must to be partly trans-
parent to the radar signal. If this function is
activated, you can specify which surface to
ignore by setting the
Ignore top surface
parameter.
Ignore top surface
This function should only be used if
DoubleSurface
is set. See description of
Double surface
. If
IgnoreTopSurface
is set
the lower surface will be presented as the
product surface.
Show negative values

parameters.
Monotone ullage/level
When a tank is filled the level value may
presentation
fluctuate up and down due to a turbulent
surface. By setting this parameter the
transmitter will not present decreasing
level values for a tank that is being filled
unless the level decreases more than an
amount given by the
MonFilt Hysteresis
parameter (holding register 1058).
For a tank that is being emptied only
decreasing values are presented, unless
the level rises more than an amount given
by the
MonFilt Hysteresis
parameter.

Invalid level is not set
If the surface echo is lost close to the top
if tank is full or empty
or
close to the bottom of the tank, the level
value full/empty will normally be displayed
as “invalid”. Set this parameter to suppress
the “invalid“ display.
Note! By setting this parameter the analog
output will not enter alarm mode for invalid
levels close to the tank bottom or close to
the antenna.

Response: the current settings are displayed.
2 In the Tank Geometry box, enter values for Distance Offset (G),
Tank Height (R) and Minimum Level Offset (C).
The Distance Offset (G) is defined as the distance between the
upper reference point and the flange
(
the flange is referred to as the
Tank Radar Pro Reference Point)
. You can use G to specify your
own reference point at the top of the tank. Set G=0 if you want the
flange as upper reference point. G is defined as positive if you use
an upper reference point above the
TR Pro Reference Point.
For
tanks with an ullage plug for hand dipping the
Tank Ullage Refer-
ence Point (dipping mark)
can be used as upper reference point,
but you can use other reference points as well.
The Tank Height (R) is defined as the distance between the upper
reference point (specified by the Distance Offset G) and the lower
reference point (zero level).
The Minimum Level Offset (C) is used to extend the measurement
range down to the tank bottom. C can not be a negative value. C is
defined as the distance between the zero level (
Tank Level Refer-
ence Point
) and the minimum accepted level. If your zero level is
located above the bottom of the tank, set the C distance equal to
Saab TankRadar® Pro Pro Setup
4-19
Edition 2. Ref. No: 306010E
the distance between the zero level and the tank bottom. Set C=0 if
you use the tank bottom as zero reference point.
The Hold Off (H) distance defines how close to the TR Pro refer-
ence point a level value is accepted. Normally the Hold Off dis-
tance does not need to be changed. However, if there are disturbing
echoes in the upper part of the tank, for example from the tank
nozzle, you can increase the Hold Off distance in order to avoid
measurements in the region close to the antenna.
The Calibration Distance is by default set to zero. It can be used to
compensate for systematic errors due to e.g. disturbances from the
tank nozzle which may be case if the gauge is not mounted properly
according to the free space requirements.

2 Select a tank shape.
Select one of the tank shape options. Choose None if you don´t
want to use volume calculations. Use one of the ideal tank shape
options if approximation of your tank with an ideal tank shape
provides sufficient accuracy. The strapping table can be used for an
arbitrary tank shape. You can enter levels and corresponding vol-
umes to obtain a close match between the actual and the calculated
volume. This option should be used in cases where the tank shape
deviates significantly from an ideal sphere or cylinder, or when you
require high accuracy.
Note! The Strapping Table option can be used only if it is in the list of
available software options in the Start Radar tab.
6Volume Calculations
Pro Setup performs Volume Calculations by using one of two
methods: predefined tank shape or strapping table. The strap-
ping table is an optional function. If it is not available a new
Start Code can be ordered from Saab Tank Control.
To enable Strapping Table select the corresponding option in the
Pro Setup/Volume window.
To configure the TR Pro Transmitter for volume calculations do
the following:
1 Select the Volume tab
Saab TankRadar® ProPro Setup
4-24
Edition 2. Ref. No: 306010E
Ideal tank
Use this option if approximation of your tank with an ideal tank
shape provides sufficient accuracy. Enter the follwoing parameters:
• Tank diameter (or the length if it is a horizontal tank).
• “Distance between zero volume and zero level mark”: set this
parameter if you do not want zero volume and zero level to match
(for example if you want to include volume below the zero level).
Strapping table
• Enter level and corresponding volume values. These figures can
typically be obtained from tank drawings or from certificate from the
tank manufacturer. If the level/volume table is based on a reference
point that is different from your reference point, you can adjust by
adding corresponding offset values in the Adjusting Offsets fields.
The Adjusting Offset is added to every value in the corresponding
column.
• Select which interpolation method to use for calculating vol-
umes between the strapping points. Normally, linear interpolation is
the preferred method. For spherical tanks, quadratic interpolation
may result in a smaller error. However, it may be necessary to try
both methods in order to evaluate which one is best in your particu-
lar case. By using linear interpolation and a sufficient number of
values in the strapping table, the interpolation error can normally be
reduced to a minimum.

7Disturbance Echo Handling
Pro Setup offers you powerful tools to handle disturbing echoes.
The False Echo tab displays a list of echoes detected by the Pro
transmitter. To optimize measurement performance you can
register false echoes which are due to disturbing objects in the
tank like beams, agitators and heating coils.
The Spectra-Threshold tab shows the amplitude of the meas-
ured signal along the tank. This diagram is often used to obtain
an overview of the conditions in the tank. You can use this dia-
gram to set a general Amplitude Threshold level in order to
filter out disturbing noise. You can also design an Amplitude
Threshold which is a function of distance from the transmitter
to the tank bottom.
Saab TankRadar® ProPro Setup

Edition 2. Ref. No: 306010E
Setting a general amplitude threshold
1 Click the
Read
button
Response: a spectrum is displayed showing the radar amplitude vs.
distance from the gauge to the product surface (ullage).
2 Set the general Amplitude Threshold. Echoes with amplitudes
below the general amplitude threshold will be disregarded. Recom-
mended threshold value:
Calm conditions: no turbulence, foam or condensation. Set ampli-
tude threshold to approximately 20% of surface echo amplitude.
Foam, agitators: check amplitude of surface echo when foam is
present or agitator is running. Set amplitude threshold to approxi-
mately 30% of surface echo amplitude.
Note that these figures are approximate estimations. Significant
deviations from these figures may be have to be used in many
cases.
Creating a customized noise threshold table
You can filter out weak disturbing echoes by creating a noise
threshold table. This technique should only be used in special
situations, for example at the bottom of tanks with weak disturbing
echoes. In such tanks the transmitter may lock at disturbances
close to the bottom when the tank is empty. Setting up a noise
threshold in this region will guarantee that the transmitter starts
following the surface when the tank is filled again.

2 Click the right-hand mouse button and
select Add point,

position and amplitude in the Ampli-
tude threshold table.
To remove points:

The following examples illustrate how the Amplitude Threshold
table can be used:
Example 1:
The amplitude threshold is used to remove the influence from
the tank nozzle.
Example 2:
In this example the amplitude threshold is used to filter out weak
disturbances close to the tank bottom. By using this technique
the risk of locking to a disturbance echo close to the tank bottom
is eliminated. This technique is particularly useful in tanks with
weak bottom echoes, like e.g. tanks with cone shaped outlets. In
this case you should also make sure that the Tank Presentation/
Bottom_echo_always_visible parameter is not set (see the de-
scription of Start Radar tab).

Registration of False Echoes
The False Echo function allows you to let the transmitter register
disturbing echoes caused by objects in the tank. This makes it
possible to detect a product surface close to a disturbance echo
even if the surface echo is weaker than the disturbing echo.
1 Select the False Echo tab
2 Click the Read button to update the list of interfering echoes.
The right-hand list displays disturbances that was detected by the
transmitter. In order to optimize the measurement performance, you
may need to register interfering echoes as described below.
Note! Registration of disturbing echoes requires that Saab´s echofixer is
enabled.
When should I register?
See the following recommendations before you register new interfering
echoes:
• Make sure that a correct amplitude threshold is set before you
register any disturbance echoes. See description of the Spectra-
Threshold window
• Keep the number of registered echoes to a minimum.
• Compare the list of interfering echoes with the tank drawing or by
visible inspection of the tank. Note if there are objects like beams,
heating coils, agitators etc. which correspond to the found echoes.
Only register echoes which can be clearly identified as objects in
the tank.
Saab TankRadar® ProPro Setup
4-30
Edition 2. Ref. No: 306010E
• Make sure that the level is stable before you register a disturbance
echo. A fluctuating level may indicate a temporary disturbance
which is not due to an interfering object.
• Do not register a disturbing echo if the amplitude is below the
general amplitude threshold, see description of the Spectra-Thresh-
old window.
• Do not register a disturbing echo if the amplitude is significantly
smaller than the amplitude of the surface echo when the surface is
at the same level as the disturbance. (In some cases weak disturb-
ing echoes can be filtered out by creating a noise threshold table,
see description of the Spectra-Threshold window).
• It may be necessary to register new disturbance echoes at a later
stage when objects have become visible due to surface movement.
Example 3:
This example illustrates a signal spectrum resulting from a tank
with an agitator. The product level is slightly below the agitator
in this example. In a case like this it is recommended that the
disturbing echo is registered, in order to achieve reliable meas-
urements when the product surface is passing the agitator. Of
course this is true also for disturbing echoes resulting from other
types of objects.

To manually add items to the list of registered disturbing echoes
You can manually enter disturbing echoes which are not present in
the list of automatically detected echoes. This function can be
useful if there are objects below the product surface which can not
be detected by the gauge at the time of installation.
To manually add echoes do the following:
1 Enter an ullage value in the Location field. The entered value may
deviate up to 100 mm from the actual position of the object.
2 Click the Insert button.
Using the Set As Surface button
If the transmitter has locked on a disturbing object you can use the
Set As Surface function to point out the surface level. If there is an
echo that you recognize as the product surface rather than an
interfering echo, mark the echo and click the Set As Surface but-
ton.

order to extend the measurement range to
the tank bottom.
4 Set the Calibration Distance. It should
normally be set to zero but can be used to
compensate for systematic errors due to
e.g. disturbances from the tank nozzle.
This may be the case if the gauge is
mounted in a nozzle which does not
conform to the free space requirements.

8. Select the False Echo option from the Advanced Setup menu (optional).
In normal operation the gauge compares
detected echoes with a list of registered
disturbance echoes, in order to decide wich
one is the actual product surface.
To view a list of echoes that the gauge has
detected select the Tank Echoes option.
5 Repeat steps 1 to 4 if you wish to register more disturbing echoes.
The Set as surface option allows you to define an echo as the
product surface.
Mark the Add new false option if you want to manually add echoes.
This may be a useful option if, for example, there are known distur-
bances below the product surface which can not be detected by the
gauge at the time of installation.
6 Click the
CNCL

To view the current list of registered disturbing echoes select the Reg. False
Echoes option:
You can select echoes from this list and
add to the list of registered echoes. You
should only register disturbing echoes
which can be identified as caused by an
object in the tank. See chapter 5
Pro Setup

for further information on when to
register disturbance echoes.
To register a disturbing echo, do the
following:
1 Move the cursor to the echo you want
to add to the list.
2 Click the

6 Tank Distances
Definitions
The Distance Offset (G) is defined as the distance between the
upper reference point and the flange (the flange is referred to as
the Tank Radar Pro Reference Point). You can use G to specify
your own reference point at the top of the tank. Set G=0 if you
want the flange as upper reference point. G is defined as positive
if you use an upper reference point above the TR Pro Reference
Point. For tanks equipped with an ullage plug for hand dipping
the Tank Ullage Reference Point (dipping mark) can be used as
upper reference point, but you can use other reference points as
well.

Edition 2. Ref. No: 306010E
The Tank Height (R) is defined as the distance between the
upper reference point (specified by the Distance Offset G) and
the lower reference point (zero level).
If no datum plate or zero level exist the tank bottom usually is
used as zero reference point. In this case C=0.
The Minimum Level Offset (C) is always positive and is defined
as the distance between the zero level (Tank Level Reference Point)
and the minimum accepted level. Normally you set the C dis-
tance in order to extend the measurement below your zero refer-
ence point.
The Hold Off (H) distance defines how close to the TR Pro
reference point a level value is accepted. Normally the Hold Off
distance does not need to be changed. However, if there are
disturbing echoes in the upper part of the tank, for example
from the tank nozzle, you can increase the Hold Off distance in
order to avoid measurements in the region close to the antenna.
