High-level & overfill alarm:

A technology upgrade is long overdue

We trust our lives to it. Radar technology

equals safety for passengers and cargo on

craft travelling sea, air and space.

No mechanical system can match this. Rosemount TankRadar STaR gives you

independent, radar-based high-level and overfill alarms for safe and reliable

loading of cargo tanks. The system is virtually maintenance-free. Never any

need to open the tank.

This is the first radar-based high-level and overfill alarm system in the market,

part of the technology pioneering within Emerson Process Management.

Introducing radar-basedhigh-level & overfill alarms

Whenever onboard a plane we

trust the pilot and the operatives

in the air traffic control tower.

But what about them? Where do

they put their trust to be able to

track planes and guide them to a

smooth landing?

You know the answer: the radar

instruments. We trust the people,

knowing they trust the radar.

For demanding applications

Just as the captain of a ship trusts

the radar for navigating. Meteo-

rologists use radars for weather

forecasts, for monitoring storms

and tornadoes. At NASA, radar

technology is used for mapping

the topography of the earth and

other planets.

The superior technology

It’s safe to say that radar is a

trusted and proven technology.

In 1976, we introduced radar tech-

nology to tank gauging.

What we pioneered then is

accepted as the industry stan-

dard today – because radar offers

safety, reliability, accuracy and

operational benefits that no other

technology can match.

Thanks to radar technology

there are no moving parts inside

the tank. Nothing ever gets stuck,

breaks down or requires any

maintenance. Thirty years and

five generations systems later,

more than 2,500 tankers have

been equipped with Rosemount

TankRadar systems. This is trust.

Liability or reliability?

In fact, those who run ships with

Rosemount TankRadar systems

onboard trust the gauging func-

tionality for topping tanks to the

limit.

The radar gauging system is so

reliable that the mechanical high-

level and overfill alarms in use

never come into play. They are not

called upon.

Some operators do not even

know whether their floats work or

not, because they cannot recall

having had any need for them.

And who knows what would

have happened if they really had

needed them?

The safety, efficacy and conve-

nience of radar is unsurpassed,

and trusted throughout the global

marine industry for accurate and

reliable tank gauging.

A superior technology

But what about mechanical sys-

tems? Considering the facts, they

can never be an alternative to

radar gauging.

Mechanical systems are not

proven. They are based on moving

parts inside the tank. They don’t

stand up to the challenge of an

aggressive tank environment. They

wear down, break down, get stuck,

get bent and can’t be trusted. And

when they break down you have

to get inside the tank to sort them

out. That’s why about 90% of tank-

ers sailing today use radar level

gauging.

Still, when it comes to high-level

and overfill alarms, more than 90%

use mechanical systems .

These are used only because

they are located separately from

the tank gauging system – they

are not used on the merits of their

reliability, safety or quality perfor-

mance.

Trust the radar

The ideal solution is to apply the

proven technology also to sepa-

rate, independent high-level and

overfill alarms. This is exactly what

we have done. Besides level gaug-

ing, Rosemount TankRadar STaR

offers independent, radar-based

high-level and overfill alarms.

In fact, high-level and overfill

are less complex applications than

level gauging. It stands to reason.

Since you can gauge accurately

and reliably over a whole measur-

ing range by means of radar, you

can also measure by means of

Reliable high-level & overfill alarms, anyone?

Rosemount TankRadar STaR offers you fully

integrated radar-based high-level and overfill

alarms – ensuring safe and reliable operation

and a long problem-free service life. The most

significant benefits are:

Virtually maintenance-free

All service from outside

No tank intrusion

No moving parts inside tank

Password-protected limits

Separate, independent channels

Battery back-up

radar a certain point of high level

and another certain point of maxi-

mum tank capacity.

Independent systems

The Tank Gauging Unit (TGU) of

Rosemount TankRadar STaR is de-

signed as three separate systems

contained in the same unit.

The three systems operate

with separate signals in separate

channels, working independently

of each other. The electronics

for data capture and information

processing outside the tank is also

designed as three separate, intrin-

sically safe systems.

Reliability at work

This system is the first radar-based

high-level and overfill alarm system

in the market, with all the benefits

of radar-based level gauging:

No moving parts inside the

tank. This means increased safety

and reliability, as well as minimal

maintenance requirements.

All service is carried out from the

outside under closed tank condi-

tions.

Automatic self-testing ensures

uninterrupted reliable function.

Battery back-up ensures unin-

terrupted operation for 30 minutes

in case of temporary power failure.

High security: password-pro-

tected change of alarm limits.

Rosemount TankRadar STaR reference: Bro Jupiter

When Swedish shipping company Broströms purchased Bro Jupiter,

the tanker was thoroughly upgraded. As part of this, a Rosemount

TankRadar STaR system was installed, utilizing both level gauging and

high-level alarm functionality. STaR replaced previous level gauging

and high-level alarm systems. Bro Jupiter, built in 1999, is a product

tanker of 14,369 dwt with 12 cargo tanks.

Multiple solutions: Depending on tanker notification,

class and type of cargo, the system can be used for level,

high level and/or overfill alarms using one, two or all

three electronic boards.

Up to three independent channels for Level/Ullage

Gauging, High-Level & Overfill Alarms – galvanically

separated and intrinsically safe. Separate systems for

data capture and information processing.

Integrated solution keeps cost down: Quick and

easy installation. One single deck penetration means

more space on deck, less cabling and a competitive

price compared to other systems.
