Recovery of Packing Material
Rosemount Tank Radar AB is fully certified according to ISO 14000
environmental standards. By recycling the plywood boxes material used
for shipping our products you can contribute to take care of the
environment.
Reuse
Experience has shown that NEFAB ExPak packaging can be used 4-5
times.
Recycling
After careful disassembly the plywood sides may be reused. Metal waste
may be converted.
Energy recovery
Products which have served their time may be divided into wood and
metal components and the wood can be used as fuel in sufficient ovens.
Due to its low moisture content (approximately 7%) this fuel has a higher
calorific value than ordinary wood fuel (moisture content approximately
20%).
When burning interior plywood the nitrogen in the adhesives may
increase emissions of nitrogen oxides to the air 3-4 times more than
when burning bark and splinter.
Note! Landfill is not a recycling option and should be avoided.

1. Introduction
The Rosemount TankRadar REX System is a monitoring and control
system for tank level gauging. The system can interface various sensors,
such as temperature and pressure sensors, for complete inventory
control.
There is a distributed intelligence in the various units of the system. The
units continuously collect and process information. When a request for
information is received an immediate response is sent with updated
information. The units communicate with each other on a field bus, the
TRL/2 Bus.
No part of the equipment is in actual contact with the product in the tank
and the antenna is the only part of the gauge that is exposed to the tank
atmosphere. The Radar Tank Gauge sends microwaves towards the
surface of the product in the tank. The level is calculated based on the
echo from the surface.
TankRadar REX can measure the level of almost any product, including
bitumen, crude oil, refined products, aggressive chemicals, LPG and
LNG, etc. Using a suitable Tank Connection Unit, the TankRadar REX
System can gauge any type of tank.

All the measured data is presented to the operator by the TankMaster
WinOpi, which in its complete version contains inventory functions. A
plant host computer can be connected for further processing of data.
All Rosemount Tank Gauging supplied parts for tank top mounting weigh
less than 25 kg (55 lb.) (except for pressure flange etc. for the LPG/LNG
Gauge). This makes it possible for one man to carry the various
TankRadar parts to the tank top for installation.

Chapter 1 Introduction
Installation
308014EN, Edition 4
May 2013
The basic parts of the Rosemount TankRadar REX System are:
• The Radar Tank Gauge, RTG, is an intelligent explosion pro-
tected instrument for measuring the level of a product inside a
tank. Four different Tank Connection Units can be attached in
order to satisfy a variety of different applications.
The RTG 3900 is equipped with auxiliary inputs such as tempera-
ture sensor inputs and analog inputs. The RTG 3900 also features
two relay outputs.
• The Data Acquisition Unit, DAU, is used for measuring tempera-
ture and can, as an option, be equipped with a Local Readout Dis-
play (LCD) for presentation of measured values.
• The Field Communication Unit, FCU, acts as a gateway and
data concentrator between the Group Bus and the Field Bus. Each
FCU can have a total of 32 RTGs and 32 DAUs connected to it.
• The Field Bus Modem, FBM, is a converter between RS-232C
and the TRL/2 Bus. It is used for connecting a PC with TankMas-
ter to the TRL/2 Bus.
• The TankMaster WinOpi is the operator´s interface for the REX
system. The WinOpi is used for setting up a REX system with
alarm handling, batch reports, automatic report handling, historical
data sampling and inventory calculations.
• The TankMaster WinSetup is a software for configuration, cali-
bration and service of a REX System.

Installation Manual

2. Safety
Rosemount TankRadar REX equipment is often used in areas where
flammable materials are handled and where an explosive atmosphere
may be present. To protect both the plant and the personnel, precautions
must be taken to ensure that this atmosphere cannot be ignited. These
areas are called hazardous areas and equipment within these areas
must be explosion protected.
A number of different explosion protection techniques have been
developed over the years. Intrinsic safety and explosion proof (or flame
proof) safety are two techniques.
2.1 Intrinsic Safety
Intrinsic safety, IS, is based on the principle of restricting electrical
energy available in hazardous-area circuits such that any sparks or hot
surfaces, that may occur as a result of electrical faults in components,
are unable to cause ignition. Intrinsic safety is the only technique
accepted for Zone 0 hazardous areas. It is also safe for personnel and
allows equipment to be maintained without the need for a gas-free
certificate.
For example, temperature measurement with the DAU is intrinsically
safe.
The basic principles of intrinsic safety are:
• All flammable materials are grouped according to the energy
needed to ignite them.
• Equipment located in hazardous areas are classified according to
the maximum surface temperature that it can produce and this
must be safe with the flammable gases that may be present.
• Hazardous areas are classified according to the probability that an
explosive atmosphere is present, and this dictates whether or not
a particular explosion protection technique may be used.
Note! For trouble shooting and repair work of components in or in connection
to intrinsically safe equipment, strict observance of the following rules is
necessary:
- Disconnect the power supply to the Radar Tank Gauge.
- Use a certified battery operated instrument only.
- Use Rosemount TankRadar REX original spare parts only.
Replacement with non-original spare parts may jeopardize the intrinsic
safety.

2.2 Explosion Proof
Explosion proof enclosures can be used when an explosion can be
allowed inside the enclosure as long as it does not spread to the outside.
The enclosure must be strong enough to withstand the pressure and
must have narrow gaps to allow the pressure to escape without igniting
the atmosphere outside of the equipment.
Note! Any substitution to non-recognized parts may impair safety.
The explosion-proof (flame-proof) enclosure of the Transmitter Head
must not be opened while the unit is powered.

3.2 Antenna Types
The Horn Antenna Gauge,
RTG 3920
The Horn Antenna Gauge is
designed for an 8” antenna to be
used in small size openings on tanks
with fixed roofs.
The RTG 3920 is designed for mea-
surement of a variety of oil products
and chemicals. However, for bitu-
men/asphalt and similar products the
Parabolic antenna is recommended.
The Parabolic Antenna Gauge,
RTG 3930
The Parabolic Antenna Gauge mea-
sures level of all types of liquids, from
light products to bitumen/asphalt.
The gauge is designed for mounting
on tanks with fixed roofs and has
custody transfer accuracy.
The design of the parabolic antenna
provides extreme tolerance against
sticky and condensing products. The
narrow beam of this antenna makes
it very suitable in narrow tanks with
internal structures.

The Still Pipe Gauge, RTG 3950
The Still Pipe Gauge is used on tanks
with still pipes and with all products
suited for still pipes.
The gauge uses a low-loss radar
propagation mode which virtually
eliminates the influence of the still
pipe condition. Measurement is
made with highest accuracy even
when the pipe is old, rusty and cov-
ered with deposits.
The Still Pipe Gauge fits 5”, 6", 8",
10" and 12" pipes. It can be mounted
on an existing still pipe and there is
no need to take the tank out of opera-
tion during installation.
There are two versions of RTG 3950:
fixed and inclined. The inclined ver-
sion has a hinged hatch, enabling full
pipe size product sampling or verifi-
cation hand-dips.
The LPG/LNG Gauge, RTG 3960
The RTG 3960 is designed for level
measurements in LPG and LNG
tanks. A 4” still pipe is used as a
wave guide for the measurement and
prevents a wavy or boiling surface
from disturbing the measurement.
Radar signals are transmitted inside
the pipe towards the surface.
The pressure sealing is a quarts win-
dow approved for use in pressure
vessels. As standard the gauge is
also equipped with a fire-proof block
valve and a vapor space pressure
sensor.
The LPG/LNG Gauge is available in
two versions, a 150 PSI version and
a 300 PSI version.
The reference pin function enables
verification of measurement without
opening the tank. By setting the
gauge into “test mode” the measured
distances are compared with the
actual distances.

4.3 Connecting the Data Acquisition Unit, DAU 2100
Instructions for connection of the Data Acquisition Unit is given on the
inside of its cover.
4.3.1 Power Supply
The Data Acquisition Unit receives its power via the local line from the
associated Radar Tank Gauge. If the distance between the Transmitter
Head and the Data Acquisition Unit is longer than 2.0 m, a junction box
must be used to connect an extension cable. This extension cable must
not be longer than 50 m. For safety reasons the ends of the unused
wires must be properly insulated and terminated. The junction box can
either be customer supplied or supplied by Rosemount Tank Gauging as
an option, see chapter 8.
4.3.2 Temperature Sensors
Under the lid of the Data Acquisition Unit there are instructions printed as
to how to connect the sensors and transducers.
Figure 4-3. The X21 terminal for temperature sensor connec-
tions.
Either Pt 100 (spot element) or Cu 100 (averaging sensor) temperature
sensors can be used. If the sensors are connected with common return
wires then jumpers must be connected in the Data Acquisition Unit
terminals.
Intrinsically safe connection of the temperature sensors, the RTDs, is
made with n + 2 wires for an n-element spot or averaging sensor. There
are spot elements with three wires for each element. The DAUs can
connect up to 14 RTDs (Resistance Temperature Detectors) on the X21
terminal on the motherboard.

4.3.3 Selecting the temperature range
A DAU can be configured for one of three different temperature ranges
by means of a multiplexer. The multiplexer for the RTDs has two different
amplification factors which are jumper selected. It is also possible to
provide an offset to the measured signal by adding a current to it.
Figure 4-4. Selecting the temperature range.
The amplification is selected on the X1 and X2 sockets and the offset is
selected on the X3 according to table 11.3. The standard setting is from -
50°C to +125°C. The database setting of the temperature range in the
TankMaster WinSetup must correspond to the setting of the jumpers.
Table 4-1. Temperature range settings.
A high precision reference resistor must be connected to the X21
terminal to positions 43, 44 and 45. Depending on the temperature range
stated in the Required System Information form, one out of three
different reference resistors is chosen and connected. See Figure 4-3
and the spare parts list in Rosemount TankRadar REX Service Manual.

5. The Remote Display Unit RDU40
The Remote Display Unit 40 (RDU 40) is a robust display unit for outdoor
use in hazardous areas. If there are less than six temperature elements
per tank, the RDU 40 is the most cost-effective solution for field display.
In this case the temperature elements can be connected directly to the
TankRadar gauge (RTG). The display functions are software controlled
by the connected TankRadar gauge.
The RDU 40 is connected by a 3-wire cable up to 100 m (330 ft) from the
RTG. Up to two units can be connected to one TankRadar Rex gauge. It
displays calculated data, such as level, average temperature, volume,
signal strength, etc. The data can be displayed in lists or as single
values. The operator can set up a user-defined window where the most
useful information is presented. This window will be shown as the default
view. The RDU 40 can view up to six spot temperature elements
connected to a TankRadar Rex gauge.
See chapter 11.5.11 for more information on how to connect the RDU40
to the REX transmitter. See also the Display Unit RDU40 User´s Guide
for instructions on how to use the RDU40.

May 2013
In order to allow proper operation and to fulfil EMC requirements, the
cable between the RDU 40 and the REX junction box should meet the
following requirements:
• Shielded cable. Minimum 3 wires. The shield shall be circular con-
nected inside the cable gland of the RDU 40 and connected to
ground in the REX junction box.
• All wires must have at least 0.25 mm individual insulation.
• Maximum total length of 100 m, both master and slave included.
• Minimum AWG 20 or 0.5 mm² for each wire.
The RDU 40-chassi shall be grounded locally to the tank. Use minimum
4 mm² or AWG 11 wire. Additional protective ground connection to the
power distribution central or the REX junction box is not recommended
except where required according to national code of practice. A ground
loop with circulating current may occur.
Note! It is not possible to use an RDU40 and a SDAU simultaneously.
If a cable with two shields is used, one shield shall be connected to
ground in the REX junction box and the other shall be circular connected
inside the cable gland of the RDU 40.

6.5 Redundancy
In order to reduce the risk of communication failure between the
TankMaster and the units connected to the TRL/2 fieldbus, two FCUs
can be connected to run in parallel to provide automatic redundancy. The
FCUs are connected with an extra cable allowing them to communicate.
The inactive FCU constantly checks if the connected FCU is active. If the
active FCU fails, it signals to the backup FCU to take over. Then the
backup FCU immediately switches to an active state. It is also possible
to use up to four TankMaster PC:s connected via different Group Buses.
Redundant FCU:s.
Two FCU:s can be connected
in parallel. One of them is con-
figured as the primary FCU and
the other as backup. The pri-
mary FCU is active. The
backup FCU listens to the com-
munication on the Field Bus
and automatically takes over
the communication without any
action from the operator if the
primary FCU fails.
Double FCU:s and
workstations.
With two FCU:s and two Tank-
Master workstations a com-
plete redundancy from control
room to RTG is achieved.

Step 1 Connect the EBM.
Step 2 Configure the gauge in WinSetup.
Step 3 Install a tank in Winsetup: Required only for Hybrid / LPG systems
for which the analog inputs are used. However it is a good idea to
install a tank and associate a gauge to it, because then it is possi-
ble to benefit from the Open Tank View function.
Step 4 Configure the gauge by using the Hybrid Calculation window
(Hybrid
system) or LPG Setup window (LPG system) in Winsetup.
Step 5 Set holding registers for free water level measurements.
Step 6 Enter information into the Enraf Emulation window in WinSetup.
Set Enraf mode and move EBM switch from Modbus to Normal
(Enraf).
Step 7 Close Enraf Emulation window. The gauge now acts like an Enraf
instrument and the EBM can be disconnected. Connect the field-
bus to the CIU.

10. Mechanical Installation
To achieve precise and trouble free measurement, it is very important to
mount the Radar Tank Gauge correctly on the tank.
Please note that if an ullage plug is required, it has to be installed
separately as there is no ullage plug on the Horn Antenna Gauge or the
Parabolic Antenna Gauge.
Note! Please see the installation drawings for more information. There is a list
of drawings in chapter 13.
10.1 Mounting a Horn Antenna Gauge
The Horn Antenna Gauge must be installed so that there are no pipes or
other obstacles that could prevent the radar beam to reach the bottom
unobstructed. Please refer also to the mechanical installation drawing for
more information on the installation requirements of the Horn Antenna
Gauge and requirements on service space.
10.1.1 Installation Requirements
Maximum height of socket is 330 mm.

10.1.2 Free Space Requirements
There are two flanges available for the Horn Antenna Gauge. One
inclines the gauge 4° and the other is horizontal. See installation drawing
for flange dimensions.
The radar beam is over 30° wide. If the wall intrudes into the 30° radar
beam when the transmitter is installed with a vertical antenna axis, the
radar beam has to be directed away from the wall by using the 4° flange.
This inclination is necessary to ensure maximum accuracy.
The horizontal flange can be used when the wall does not intrude into the
30° radar beam.
For special cases, where maximum accuracy is not required, the
horizontal flange can be used even when the wall intrudes into the radar
beam. In doubtful cases, please contact please contact Emerson
Process Management / Rosemount Tank Gauging or one of its
representatives for advice.

10.2 Mounting the Parabolic Antenna Gauge
See also Mechancial Installation drawings 9150072-982, 9240003-944, -
947 for further information.
10.2.1 Inclination
The inclination of the gauge should not exceed 1.5 ° towards the center
of the tank. For products with high condensation, like bitumen/asphalt
applications, the radar beam should be directed vertically without any
inclination.
The RTG 3930 is mounted on the tank nozzle by using the Flange Ball.
The Flange Ball is designed to make it easy to adjust the inclination of
the transmitter within the specified limits.
There are two versions of the Flange Ball: T30 and T38-W. Model T 38-
W is welded on the flange. Model T 30 is attached to the flange with a
nut. The Flange Ball must be mounted on the tank flange prior to
mounting the gauge on the tank nozzle.
Inclination - Flange Ball model T30
For Flange Ball model T30 the flange may lean a maximum of 4.5° away
from the tank wall, and a maximum of 2° towards the tank wall. It must
also be horizontal within ±3° along the tank wall, see Figure 10-4,
Figure 10-5 and Figure 10-6.

10.3.1 Introduction
This instruction covers installation of the RTG 3950 Still-pipe array
antenna. It is available for pipe size 5, 6, 8, 10 and12 inch.
The RTG 3950 Still-pipe Array antenna is designed for still-pipe
mounting and can be mounted on existing still-pipes without taking the
tank out of operation.
There are two versions available in order to suit various demands for
easy installation and maintenance:
• The RTG 3950 Fixed version. This version has a flange for easy
mounting when there is no need for opening the tank.
• The RTG 3950 Inclined version has the transmitter head mounted
on a fixed stand. The hinged hatch allows the tank to be opened
by removing the Waveguide Connection. This version is suitable
when the tanks needs to be opened and cables are installed with
fixed conduits.

10.4 Mounting a LPG/LNG Gauge
The LPG/LNG Gauge fits to a 6" flange and requires a still pipe for
measurement.
Please refer to the mechanical installation drawing for more detailed
information of the requirements on the installation of the LPG/LNG
Gauge.
10.4.1 Temperature and Pressure Measurement.
A prerequisite for high accuracy level-measurements in LPG/LNG tanks
is that temperature and pressure measurements are made. The REX
transmitter can interface pressure sensors and up to six temperature
sensors.
10.4.2 Still Pipe.
A still pipe must be installed before the gauge is installed. The still pipe is
customer supplied and should be manufactured according to the
drawings specified in chapter 13.
Three types of steel pipe can be used:
• inner diameter of 100 mm and 2-3 mm wall thickness, or
• 4" SCH 10 stainless steel pipe, or
• 4" SCH 40 stainless steel pipe.
Specify the pipe type in the Required System Information (RSI) form.
The still pipe must be vertical within ±0.5°. The customer flange must be
horizontal within ±1°.
The Still Pipe is manufactured with a number of holes in order to provide
pressure equalization so that the product level inside the pipe is equal to
the level in the rest of the tank. The diameter of the holes should be 20
mm or 3/4".
All holes must be placed along a line on one side of the pipe and aligned
with a bolt hole on the Pipe Flange (see Figure 10-14). The position of
the holes must be clearly marked on the Pipe Flange. The Reference Pin
(see section 10.4.3) must be directed towards this bolt hole. The flange
marking is used to properly align the gauge with the Reference Pin.

10.4.3 Reference Pin and Reflector
One of the holes on the Still Pipe is used for mounting a Reference Pin
which enables verification of the measurement when the tank is
pressurized.
The Reflector is mounted at the lower end of the Still Pipe and is
integrated with a ring that is used for calibrating the gauge.
See installation drawings for LPG/LNG Still Pipe for information on
where to place the reference pin in the still pipe. Enclosed with reference
pin and reflector are instructions on how to install these.
Figure 10-15. Still Pipe with reflector and reference pin.
The reflector can be attached to the Still Pipe by using one of three
methods:
• Welding
• M4 screw and nut
• Riveting
For pipe dimensions 4 inch SCH 40 and DN 100 an extra ring is needed
for the reflector as illustrated below:

10.4.4 Extension Pipe for Minimum Distance.
The Radar Tank Gauge should be placed so that there is always 800 mm
or more between the flange and the maximum product level. If the tank is
filled completely, an extension pipe can be mounted to raise the Radar
Tank Gauge so that it measures correctly all the way up to the maximum
level. See Figure 10-18.

10.4.5 Installation on the tank.
Follow this step by step instruction when installing the LPG/LNG Gauge.
Note! There must be a clear mark on the pipe flange to show the direction of
the reference pins in the still pipe. Carefully check that the Closing is
mounted in the appropriate angle relative to that mark.
See also the installation drawings. See chapter 13 for list of drawings.
The Lower Flange, the ball valve and the Closing are preassembled and
delivered as one unit.
1Check that all parts and tools
are available before carrying
them to the tank top.
2Install the still pipe according to
mechanical installation drawing
9150072-924.
3Enter the Cone into the still
pipe to make sure it fits. Maxi-
mum gap between the Cone
and the pipe is 2 mm.
4Mount the Pipe Cone onto the
Closing using four M6 Allen
head screws. Be careful when
handling the Closing with the
Pipe Cone mounted onto it as it
is very important that the Pipe
Cone is not deformed.
Do not remove the yellow pro-
tective cap.

11. Electrical Installation of the REX Gauges
Warning! Isolate and terminate ends of unused wires. The intrinsic safety may be
jeopardized if any cable ends are hanging loose. Use certified battery
operated instruments only. Use Rosemount Tank Gauging original spare
parts only.
Note! See the instructions in the electrical installation drawings for further
information. See list of drawings in chapter 12.
11.1 Cabling for Power Supply
Cables used for the power supply connection must be suitable for the
supply voltage in question and also approved for use in hazardous area
where it is applicable. In the USA, for example, explosion proof conduits
must be used in the vicinity of the tank. Appropriate cross sectional area
of wires must be used in order to prevent a too high voltage drop to the
connected device.
Table 11-1 and Table 11-2 show examples of typical voltage drops for
various cable lengths, wire areas and supply voltages at the maximum
power consumption of 80 W (30 W for 24 VDC).
The presented voltage drops should only be treated as guidelines since
actual values depend on the particular cable type that is used for the
installation. The figures shaded in grey indicate combinations of lengths
and areas that might result in too high voltage drops.
Note that the REX gauge can use a wider range of supply voltages than
shown in Tables 11-1 and 11-2:
• 100-240 VAC,
• 34-70 VAC,
• 48-99 VDC,
• 20-28 VDC.

11.2 Cabling for TRL/2 Bus
The TRL/2 Bus requires a twisted and shielded pair with an area of min
0.50 mm2 (AWG 20 or similar). The maximum length of the TRL/2 Bus is
approximately 4 km. The TRL/2 Bus can normally use existing cables in
the tank area.
Note! Wherever two or more TRL/2 Buses run alongside each other, sharing
the same cable or conduit tube, use twisted and shielded wire and make
sure that each pair of bus wires is individually shielded in order to avoid
crosstalk.
Figure 11-1. Individually shielded pairs of cables.
11.3 Recommended Cables
Table 11-3 shows typical cable types that can be used for connecting the
REX gauge. Other cables of similar type may also be used.
Table 11-3. Example of applicable cable standards.
11.4 Grounding
According to national code of practice the Transmitter Head or Data
Acquisition Unit can be grounded by connecting an exterior 4 mm2 wire
to a potential equalization network, or, if no such exists, to the tank
structure. A grounding lug is available on the enclosure for this purpose.
Note! When the enclosure is connected to a potential equalizing network or to
the tank structure, the protective ground with the power supply must not
be connected.
If the enclosure is not externally grounded, the protective ground with the
power supply should be connected.

11.5 Connecting the Radar Tank Gauge 3900
The RTG 3900 is equipped with two cable outputs for intrinsically safe
and non-intrinsically safe connections. Wires are clearly marked with
numbers and designation of wires is shown on a printed plate at the
cable outputs. The transmitter can also be equipped with an integrated
junction box (JBi).
Figure 11-2. Electrical connections on the RTG 3900 REX.
W11 is for the non-intrinsically safe power supply, the TRL/2 Bus and
relays. The power supply and the TRL/2 Bus can be connected via an
external junction box, or directly to the transmitter if it is equipped with
the Integrated Junction Box. See Chapter 8: Junction Boxes for further
information on how to use the different Junction Boxes. An external
junction box can either be customer supplied or supplied by Emerson
Process Management/Rosemount Tank Gauging as an option.
Wires in the cable output that are not used must be properly insulated
and terminated in the junction box.
W12 is for the intrinsically safe connection of Data Acquisition Unit
(DAU), Display Panel RDU40, analog inputs and temperature sensors.
There are two versions of the W12 cabling: 8 or 15 wires. The 15 wire
version is used when temperature sensors are connected to the
transmitter.

May 2013
The RTG 3900 version without Integrated Junction Box is delivered with
a 2 m long cable. If the distance between the transmitter and connected
devices is longer than 2 meters, a junction box must be used to connect
an extension cable. The extension cable must not be longer than 50 m.
An external junction box can either be customer supplied or supplied by
Emerson Process Management/Rosemount Tank Gauging as an option.
Note! For safety reasons unused wires must be properly insulated and
terminated.
A flexible protective hose for the wires is delivered with the transmitter. If
a DAU is used, it is very important that a continuous metal shield covers
the wires between the Transmitter Head and the DAU to avoid
electromagnetic interference between cables. If an extension cable is
used, both the cable and the junction box must provide good shielding.
Note! Select external fuse rating with respect to area temperature classification
(T1-T6) and maximum expected ambient temperature to prevent
overheating of the internal wiring in the JBI junction box (0.5 mm²).
Example: Max. allowed (fault) current in a T4 installation with 70°C

11.5.5 TRL/2 Bus
The transmitter is connected to a workstation via a a Field
Communication Unit (FCU) and a Field Bus Modem (FBM). The FBM
converts the USB (or RS232) signal to a TRL/2 Modbus signal.
Each TRL/2 Bus can connect up to 8 units.
Figure 11-6. Connection of the TRL/2 Bus
Connect the TRL/2 Bus with a single pair of shielded twisted wires. The
maximum length is 4 km. Use cables with an area of at least 0.5 mm2
(AWG 20 or similar).
Once connected to the TRL/2 Bus you can configure the transmitter as
well as monitor tank data by using the TankMaster WinSetup/WinOpi
software. The TankMaster software provides a modern user-friendly
interface including functions for monitoring tank data such as level,
temperature and inventory data.

11.5.8 Temperature Sensors
Up to six spot temperature elements can be connected to the REX
transmitter if the Temperature Multiplexer Card (TMC) is installed. The
TMC board must be configured in accordance with the type of sensor
that is used (see chapter 4.1.8 in the REX Service Manual for detailed
instructions on how to configure the TMC card):
• The internal connections to the TMC board must be properly set
for 1-3 three-wire independent elements (socket X3 on the TMC),
or
1-6 sensor elements with common return (socket X2 on the TMC).
• The TMC board must be adapted to the type of sensor that is
used. For average elements or sensor elements with common
return wire there must be three jumpers in socket X4 and one
jumper in socket X5.
For three-wire independent elements no jumpers shall be
installed.
Normally these jumpers are installed at factory, and do not need to
be changed unless you change to other sensor types than origi-
nally specified.
Use the TankMaster WinSetup program to configure the temperature
sensors. WinSetup allows you to configure the transmitter by specifying
sensor type, sensor positions and measurement range.
Connecting the Temperature Sensors
Temperature sensors must be connected in the correct order starting
with connection X12:8 for temperature sensor one. The other sensors
are connected as shown in Tables 11-8 and 11-9.
Spot Elements
Spot temperature sensors use two wires per sensor plus one wire for
common return current.

12. Sensor Installation
The TankRadar REX system includes various integrated equipment such
as temperature sensors and Water Level Sensors.
12.1 Temperature Sensors
Up to six temperature sensors can be connected to a REX Radar
Transmitter Gauge (RTG). By using a Data Acquisition Unit (DAU) a
maximum of 14 temperature sensors can be used in a tank.
Figure 12-1. Up to six temperature elements can be connected
to a REX gauge.
The Multiple Spot Thermometer (MST) measures the temperature with a
number of Pt 100 elements placed at different heights to provide a
temperature profile and an average temperature. The spot elements are
placed in a flexible gas tight tube made of stainless steel which can be
anchored to the tank bottom.

12.2 Water Level Sensor
The Water Level Sensor (WLS) measures the free water level below an
oil surface. It outputs a 4-20 mA signal which is connected to the level
gauge. The WLS can also be equipped with integrated Multiple Spot
Temperature sensors. Up to six temperature sensors can be connected
to a Rosemount TankRadar REX transmitter.
12.2.1 Mechanical Installation
The WLS can be anchored by attaching a weight at the end of the sensor
or by putting a weight on top of it. In the latter case the ring at the end of
the probe can be removed in order to make sure that measurements are
performed as close to the tank bottom as possible.

12.2.2 Configuration
It is important that the 4 mA and the 20 mA levels are properly configured
in order to obtain correct water level readings from the WLS. The
distance “X” between the Tank Zero Level and the Water Zero Level
has to be considered when configuring the WLS. “X” can be calculated
from known tank distances as illustrated in Fig. 12-8.
Figure 12-8. Tank geometry for the Water Level Sensor
The distance X can be calculated with the following formula:
X = (R-L1) - (L-L2).
X=distance between the Tank Zero Level and the Water Zero Level.
L=distance between Water Zero Level and mark on the upper part of the
WLS.
R= Tank Reference Height. This is the distance between the Tank
Reference Point and the Tank Zero Level.
L1=distance between the Tank Reference Point and the temperature
sensor flange.
L2=distance between the mark on the top of the WLS and the
temperature sensor flange.

For inventory management with TankMaster WinOpi the WLS is
configured in TankMaster WinSetup.
The Lower Range Value (4 mA) and the Upper Range Value (20 mA) are
given by the following formulas:
Upper Range Value (20 mA) = LA + X
Lower Range Value (4 mA) = X
where LA is the active length of the Water Level Sensor, and X is the
distance between the Water Zero Level and the Tank Zero Level.
The configuration of the WLS can basically be divided into three cases
as illustrated below:
The Water Zero Level is below the
Tank Zero Level.
In this case the 4 mA point on the
WLS is below the Tank Zero Level.
Note that when the 4 mA point is
below the Tank Zero Level the 4 mA
value is negative, i.e. X<0.
Example: LA=500 mm, X=-50 mm.
4 mA value=-50 mm.
20 mA value=500 + (-50)=450 mm.
The Water Zero Level is equal to
the Tank Zero Level.
In this case the 4 mA point on the
WLS corresponds to the Tank Zero
Level. The 4 mA value=0.
Example: LA=500 mm, X=0 mm.
4 mA value=0 mm.
20 mA value=500 mm.

The Water Zero Level is above the
Tank Zero Level.
In this case the 4 mA point on the
WLS is above the Tank Zero Level.
Note that when the 4 mA point is
above the tank Zero Level the 4 mA
value is positive, i.e. X>0.
Example: LA=500 mm, X=70 mm.
