Introduction
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.

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-touse 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.

Introduction
Measurement Principle
The Saab TankRadar Pro transmitter sends a microwave signal with a continuously varying frequency towards the liquid surface. When the reflected
signal returns to the antenna, it is mixed with the outgoing signal.

Reflected
Frequency (GHz)
fmax
∆f
f1
∆f ~ ∆t ~ d

Time

∆t
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 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 measurements.
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 spectrum of all echoes in the tank. From this frequency spectrum the surface
level is extracted. In combination with Saab´s echofixer, FFT allows meas-

Introduction
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.

The Distance Offset 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 Reference Point (dipping
mark) can be used as upper reference point, but you can use other
reference points as well. Finish by pressing the SAVE button.

The tank calibration distances are defined as illustrated on
the next page.
Set the Distance Offset (G).
The Distance Offset 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 Reference
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).
Set the Minimum Level (C).
The Minimum Level Offset 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 distance in
order to extend the measurement range to
the tank bottom.
5-18
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.

See chapter Tank Distances for further information on how to set

The following steps are only applicable when a non-standard
antenna is used.
Set the Holdoff Distance (H). The Hold Off distance defines how
close to the RTG 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.
Set the Tank Connection Length TCL. This value is set automatically when you use one of the standard antennas.

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.

Tank Distances
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 distance in order to extend the measurement below your zero reference 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.
