2 Overview

2.1 Introduction

The Rosemount™ 5900S is a two-wire radar level gauge for high accuracy non-contact
measurements. The level gauge continuously emits a radar signal with varying frequency
towards the product surface. This allows very accurate level measurements by processing
the difference between the frequencies of the emitted and received radar signals.

The Rosemount 5900S is an integral part of the flexible Rosemount Tank Gauging system.
The advanced and robust design makes it suitable for a vast range of applications. It is
designed for high accuracy level measurements as well as handling complex tank shapes
and obstacles in the tank that may interfere with measurement signals.

2.5 System overview

The Rosemount Tank Gauging system is a state-of-the art inventory and custody transfer
radar tank level gauging system. It is developed for a wide range of applications at
refineries, tank farms and fuel depots, and fulfills the highest requirements on
performance and safety.

The field devices on the tank communicate over the intrinsically safe Tankbus. The
Tankbus is based on a standardized fieldbus, the FISCO
integration of any device supporting that protocol. By utilizing a bus powered 2-wire
intrinsically safe fieldbus the power consumption is minimized. The standardized fieldbus
also enables integration of other vendors’ equipment on the tank.

The Rosemount Tank Gauging product portfolio includes a wide range of components to
build small or large customized tank gauging systems. The system includes various
devices, such as radar level gauges, temperature transmitters, and pressure transmitters
for complete inventory control. Such systems are easily expanded thanks to the modular
design.

The Rosemount Tank Gauging system is a versatile system that is compatible with and can
emulate all major tank gauging systems. Moreover, the well-proven emulation capability
enables step-by-step modernization of a tank farm, from level gauges to control room
solutions.

It is possible to replace old mechanical or servo gauges with modern Rosemount Tank
Gauging devices, without replacing the control system or field cabling. It is further
possible to replace old HMI/SCADA-systems and field communication devices without
replacing the old gauges.

There is a distributed intelligence in the various system units which continuously collect
and process measurement data and status information. When a request for information is
received an immediate response is sent with updated information.

The flexible Rosemount Tank Gauging system supports several combinations to achieve
redundancy, from control room to the different field devices. Redundant network
configuration can be achieved at all levels by doubling each unit and using multiple control
room work stations.

Overview

2.5.1 TankMaster HMI software

Rosemount TankMaster is a powerful Windows-based Human Machine Interface (HMI) for
complete tank inventory management. It provides configuration, service, set-up,
inventory, and custody transfer functions for Rosemount Tank Gauging systems and other
supported instruments.

Rosemount TankMaster is designed to be used in the Microsoft® Windows environment
providing easy access to measurement data from your Local Area Network (LAN).

The Rosemount TankMaster WinOpi program lets the operator monitor measured tank
data. It includes alarm handling, batch reports, automatic report handling, historical data
sampling as well as inventory calculations such as Volume, Observed Density and other
parameters. A plant host computer can be connected for further processing of data.

The Rosemount TankMaster WinSetup program is a graphical user interface for
installation, configuration and service of devices in the Rosemount Tank Gauging system.

2.5.2

Rosemount 2460 System Hub

The Rosemount 2460 System Hub is a data concentrator that continuously polls and
stores data from field devices such as radar level gauges and temperature transmitters in a
buffer memory. Whenever a request for data is received, the system hub can immediately
send data from the updated buffer memory for a group of tanks.

Measured and calculated data from one or more tanks is communicated via the
Rosemount 2410 Tank Hub to the system hub buffer memory. Whenever a request is
received, the system hub can immediately send data from a group of tanks to a
TankMaster PC, or a host.

The Rosemount 2460 can be used to connect devices from other vendors as well, such as
Honeywell® Enraf and Whessoe.

The Rosemount 2460 has eight slots for communication interface boards. These boards
can be individually configured for communication with hosts or field devices. They can be
ordered either for TRL2, RS485, Enraf BPM or Whessoe 0-20 mA/RS485 communication.
Two slots can also be configured for RS232 communication.

One of the system hub’s three Ethernet ports is used for Modbus TCP connection to host
systems. By simply connecting the system hub to the existing LAN network,
communication over Ethernet is established.

The system hub can provide redundancy for critical operations, by using two identical
devices. The primary system hub is active and the other one is in passive mode. If the

3.2 Installation considerations

When finding an appropriate location on the tank for a Rosemount 5900S Radar Level
Gauge, the conditions of the tank must be carefully considered. The Rosemount 5900S
should be installed so that the influence of disturbing objects is kept to a minimum,
preferably outside the radar signal beam.

Ensure that environmental conditions are within specified limits as listed in Specifications

and reference data.

Ensure that the Rosemount 5900S Radar Level Gauge is installed such that it is not
exposed to higher pressure and temperature than specified in Specifications and reference

data.

It is the responsibility of the user to ensure that the device meets the specific inside tank
installation requirements such as:

• chemical compatibility of wetted materials

• design/operation pressure and temperature

For a complete specification of the Rosemount 5900S device, you can identify the model
code on the attached antenna label and match with data in Ordering information.

3.2.1

Do not install the Rosemount 5900S in non-intended applications, for example
environments where it may be exposed to extremely intense magnetic fields or extreme
weather conditions.

Antennas with plastic surfaces and painted surface, may under certain extreme conditions
generate an ignition-capable level of electrostatic charge. When installing in hazardous
areas ensure using tools, cleaning material etc. which can not generate electrostatic
charge.

Horn antenna requirements

The Rosemount 5900S with Horn Antenna must be installed so that there are no pipes or
other obstacles that could prevent the radar beam from reaching the tank bottom
unobstructed. There are two flanges available; a horizontal flange for vertical installation,
and an inclined flange for installation close to the tank wall.

Please refer to mechanical installation drawings for more information on the installation
requirements of the Horn Antenna and service space requirements.

3.2.4 LPG/LNG antenna requirements

Temperature and pressure measurement

Measurements of temperature and pressure is a prerequisite for high accuracy level
measurements in LPG/LNG tanks. A Rosemount Tank Gauging system may include
Rosemount 5900S Radar Level Gauges, Rosemount 2240S Multi-input Temperature
Transmitters, Rosemount 644 Temperature Transmitters as well as pressure transmitters
in order to obtain all necessary measurement variables.

Still-pipe and Verification Pin

A still-pipe must be installed prior to the gauge installation. The still-pipe is customer
supplied and should be manufactured according to the installation drawings.

Three types of steel pipe are recommended:

• DN100

• 4 inch SCH 10 stainless steel pipe

• 4 inch SCH 40 stainless steel pipe

When ordering the level gauge specify the pipe type in the Required System Information
(RSI) form.

The still-pipe must be vertical within ±0.5° and the customer flange must be horizontal
within ±1° as illustrated in Figure 3-11.

The still-pipe is manufactured with a number of holes to allow proper circulation of the
product, and to ensure equalization of product density inside and outside the pipe. The
hole diameter should be 20 mm or 3/4”. All holes in the upper still-pipe section must be
placed along a line on one side of the pipe.

The Verification Pin allows you to verify Rosemount 5900S level measurements when the
tank is pressurized. It is mounted on the still-pipe in a hole oriented 90 degrees to the
other holes.

The Verification Pin should be placed at a position of 1200 mm (47 in.) below the flange as
illustrated in Figure 3-11. There must be a minimum distance of 200 mm (8 in.) between
the Verification Pin and the maximum product level. In order to fulfill this requirement, the
Verification Pin may be mounted higher, up to 1000 mm below the flange.

The Verification Pin must be aligned with a bolt hole on the still-pipe flange as illustrated in

Figure 3-11. The Verification Pin’s position must be clearly marked on the still-pipe flange

(see Figure 3-11) to allow proper alignment of the Rosemount 5900S gauge.

Extension pipe for minimum distance

The Rosemount 5900S Radar Level Gauge should be placed such that there is a minimum
gap of 1200 mm (47 in.) between the flange and the maximum product level (see Still-

pipe and Verification Pin). If necessary, an extension pipe can be used to raise the level

gauge. This will allow measurements closer to the top of the tank than would otherwise be
possible, as illustrated in Figure 3-16.

3.4.1 Cable/conduit entries

The electronics housing has two entries for ½ - 14 NPT. Optional M20×1.5, minifast and
eurofast adapters are also available. The connections must be made in accordance with
local or plant electrical codes.

Make sure that unused ports are properly sealed to prevent moisture or other
contamination from entering the terminal block compartment of the electronics housing.

Note

Use the enclosed metal plugs to seal unused ports. The plastic plugs mounted at delivery
are not sufficient as seal!

Note

Thread sealing (PTFE) tape or paste on male threads of conduit is required to provide a
water/dust tight conduit seal and to meet the required degree of ingress protection as
well as to enable future removal of the plug/gland.

3.4.2

NPT is a standard for tapered threads. Engage the gland with 5 to 6 threads. Note that
there will be a number of threads left outside the housing as illustrated in Figure 3-19.

Figure 3-19: Cable Entry with NPT Threaded Gland

A. The NPT threaded gland leaves a number of threads outside the housing

Ensure that glands for the cable entries meet requirements for IP class 66 and 67.

Grounding

The housing should always be grounded in accordance with national and local electrical
codes. Failure to do so may impair the protection provided by the equipment. The most
effective grounding method is direct connection to earth ground with minimal
impedance.

There are three grounding screw connections provided. Two are located inside the
terminal compartment of the housing and the third is located on the housing. The internal

ground screws are identified by a ground symbol: .

Note

Grounding the transmitter via threaded conduit connection may not provide sufficient
ground.

Grounding - FOUNDATION™ Fieldbus

Signal wiring of the fieldbus segment can not be grounded. Grounding out one of the
signal wires may shut down the entire fieldbus segment.

Shield wire ground

To protect the fieldbus segment from noise, grounding techniques for shield wire usually
require a single grounding point for shield wire to avoid creating a ground loop. The
ground point shall be located at the power supply.

The devices designed for “daisy-chain” connection offer an isolated shield loop-through
terminal in order to enable a continuous shield throughout the Tankbus network.

In order to avoid unintentional grounding points, the cable shield inside the terminal
compartment must be isolated.

3.4.3

Cable selection for the Tankbus

Use shielded twisted pair wiring for the Rosemount 5900S Series in order to comply with

(4)

FISCO
fieldbus cable. The cables must be suitable for the supply voltage and approved for use in
hazardous areas, where applicable. In the U.S. explosion-proof conduits may be used in
the vicinity of the vessel.

Use wire rated at least 5 °C above maximum ambient temperature.
We recommend cable size 1.0 mm2 or 18 AWG in order to facilitate wiring. However,

cables within the range 0.5 to 1.5 mm2 or 20 to 16 AWG can be used.
The FISCO FOUNDATION™ Fieldbus specification requires that cables for the Tankbus comply

with the following cable parameters:

Table 3-8: FISCO Cable Parameters

3.4.4 Hazardous areas

When the Rosemount 5900S level gauge is installed in hazardous areas, local regulations
and specifications in applicable certificates must be observed.

Certificates for Rosemount Tank Gauging products, such as the Rosemount 5900, are
available on Emerson.com/Rosemount Tank Gauging.

3.4.5 Power requirements

The Rosemount 5900S is powered over the intrinsically safe Tankbus by the Rosemount
2410 Tank Hub. The 2410 feeds the intrinsically safe fieldbus segment by acting as a FISCO
power supply on the Tankbus.

When installed in a FOUNDATION Fieldbus system without a Rosemount 2410 Tank Hub, the
Rosemount 5900S is powered by the FF segment.

3.4.6

3.4.7

Power budget

The Rosemount 5900S power consumption is 50 mA for standard devices, and 100 mA for
the Rosemount 5900S 2-in-1 versions. This has to be considered when connecting field
devices to the Tankbus. See section “Power Budget” in the Rosemount 2410 Tank Hub

Reference Manual for more information.

Tankbus

The Rosemount Tank Gauging system is easy to install and wire. Devices can be “daisy­chained” thus reducing the number of external junction boxes.

In a Rosemount Tank Gauging system devices communicate with a Rosemount 2410 Tank
Hub via the intrinsically safe Tankbus. The Tankbus complies with the FISCO
Fieldbus standard. The Rosemount 2410 acts as power supply to the field devices on the
Tankbus. A FISCO system enables more field devices to be connected to the segment
compared to conventional IS systems based on the entity concept.

Termination

A terminator is needed at each end of a FOUNDATION™ Fieldbus network. Generally, one
terminator is placed in the fieldbus power supply, and the other one in the last device in
the fieldbus network.

Note

Ensure that there are two terminators on the fieldbus.

(5)

FOUNDATION

In a Rosemount Tank Gauging system the Rosemount 2410 Tank Hub acts as power
supply. Since the tank hub normally is the first device in the fieldbus segment, the built-in
termination is enabled at factory.

78 Reference Manual

Reference Manual Installation

00809-0100-5900 November 2021

Temperature Transmitter also have built-in terminators which can easily be enabled by
inserting a jumper in the terminal block when necessary.

Segment design

When designing a FISCO fieldbus segment a few requirements need to be considered.
Cabling has to comply with FISCO requirements.

You will also have to ensure that the total operating current of the connected field devices
is within the output capability of the Rosemount 2410 Tank Hub. The 2410 is able to
deliver 250
the total current consumption is less than 250 mA.

Another requirement is to ensure that all field devices have at least 9 V input voltage at
their terminals. Therefore you will have to take into account the voltage drop in the
fieldbus cables.

Distances are normally quite short between the Rosemount 2410 Tank Hub and field
devices on the tank. In many cases you can use existing cables as long as the FISCO
requirements are fulfilled.

Typical installation

The example in Figure 3-20 illustrates a system with daisy-chained field devices on a single
tank. Terminators are installed at both ends of the fieldbus segment as required in a
FOUNDATION Fieldbus system. In this case terminators are enabled in the Rosemount 2410
Tank Hub and a field device at the end of the network segment.

In addition to the field instruments on the Tankbus, Figure 3-20 illustrates how an
instrument such as a pressure transmitter can be connected to the intrinsically safe 4 -20
mA analog input of the 2410 Tank Hub.

Maximum number of HART Slave Devices:

• Passive current loop: 5

• Active current loop: 3

The Rosemount 5900S supports basic configuration which is sufficient in most cases.
There are a number of advanced configuration options available as well, which may be
used for special applications when further fine-tuning is needed.

4.2.1 Basic configuration

Basic configuration includes specifying parameters for a standard configuration. This is
sufficient in most cases. A basic configuration includes the following items:

• Measurement units

• Tank geometry; tank height, tank type, tank bottom type, pipe diameter, hold off

distance, calibration distance, etc.

4.2.2

• Process conditions; rapid level changes, turbulence, foam, solids, product dielectric

range

• Volume; standard tank types, strapping table

• Tank scan; analyze the Rosemount 5900S measurement signal

• Empty tank handling; optimize measurements close to the tank bottom

See Basic configuration for more information.
