Embedded resource provides customer satisfaction
Professional project services reduce risk and improve project timelines by providing
immediate onsite support, explains Endress+Hauser
arge global engineering, procurement
and construction (EPC) firms working
on substantial petrochemical projects are
often challenged by clients to minimize
risk, maintain the project timeline and stay
on budget, points out instrumentation and
control specialist Endress+Hauser. Most
large EPC companies acquire complex projects
that are colossal in scope - not just in
terms of their size, but also due to the many
stakeholders who are invested in the project.
These projects are becoming increasingly
complex and demanding. Schedules
and budgets are tight, and safety is crucial.
For contractors facing such pressure,
embedded resources who join the engineering
team can provide expert knowhow
and help meet the project's goals,
Endress+Hauser notes.
An embedded resource is a subject matter
expert who is embedded into the engineering
team and works to help reduce risk
by providing immediate onsite support. In
the case of Endress+Hauser, the products,
solutions and services engineer provides
L
needed, and also reduces risk of increased
direct costs to the project. Close collaboration
with the firm's engineering disciplines
helps to optimize all interfaces to process,
control, electrical and piping.
" Having an Endress+Hauser representaClose
collaboration with the firm's
engineering disciplines helps to
optimize all interfaces to process,
control, electrical and piping
knowledge and expertise on process automation
field devices. By resolving issues
immediately, the embedded resource helps
to keep the project on time and on budget.
Having this resource also reduces repetitious
external communications and the inherent
delay caused by emails and phone
calls, keeping other resources productive.
The manpower is supplied to the project as
tive in house is an added value and creates
a seamless experience, " said Shannon M.,
Senior Control System Engineer for a large
EPC firm. " If a client has an issue or I have
a question on dimensions, they are right
there to assist. "
" We have an embedded Endress+Hauser
engineer that works along with our project
team. This has helped save time by getting
quotes, dimensional data and questions
answered in a shorter amount of time. With
the right person, this could be beneficial in
other projects, " said Warren W., the firm's
Project Engineer.
Having an embedded resource on the
project helps EPC firms provide fast, dependable
and reliable services and solutions
to their clients.

High-frequency radar targets small vessels
With its 80 GHz frequency and small-diameter antenna, VEGA's VEGAPULS 64 works in
small vessels where radar level measurement was previously impractical
T
he current trend in the chemical industry
is towards smaller, specialized batches.
This results in equipment and containers
with reduced volume. But engineers everywhere,
including those in technical centres
and pilot installations, have frequently run
up against limits when they tried to use
radar level measurement technology in very
small production setups. In particular, factors
like the dead band of the sensors, the
size and design of the antennas, and measurement
uncertainty near the tank bottom
often forced them to use weighing systems
or pressure transmitters instead.
VEGA's VEGAPULS 64, the world's first
radar level sensor for liquids operating at a
frequency of 80 GHz, now has an antenna
system integrated directly into the process
fitting. Since no antenna protrudes into the
vessel, it is possible to measure right up to
the process fitting itself. This gives greater
flexibility because practically all of the container
volume can be utilized.
Thanks to the tightly focused measuring
beam - with an antenna diameter of
80 mm, the transmission signal has an initial
angle of just 3° - using the instrument
in tanks with heating coils and agitators
has become much easier. Another advantage
of VEGAPULS 64 is its larger dynamic
range, which results in higher measurement
certainty, especially when there is buildup,
condensate, foam or a turbulent liquid surface
in the vessel.
In pilot plants or applications where
very high chemical resistance is required,
glass facilities are often used. Because of
its small sensor dimensions and small process
fittings, the VEGAPULS 64 can be very
easily adapted to these applications. Radar
sensors are able to measure the level of the
product through the surface of a glass container.
The tight focus of the VEGAPULS 64
beam makes this much easier than in the
past, when big antenna systems have been
necessary.
In recent years, non-contact radar level
measurement technology has taken over
many applications in the chemical industry.
The big advantage of radar technology is

its immunity to process conditions such as
temperature, pressure and density. With the
VEGAPULS 64, levels can now be measured
in applications where the process and structural
conditions were previously not suitable
for radar.
