Challenging applications
" The chemical industry has challenges
associated with hazardous
and corrosive fluids, as well as high
pressures and high temperatures,
so finding flow instrumentation that
contains all stainless-steel wetted
components or exotic materials is
important in these challenging applications, "
notes
Mike
Iverson,
general
manager at AW-Lake (Oak
Creek, Wis.; www.aw-lake.com).
In addition, he says, many users
in the chemical and oil-and-gas industries
are interested in the flexibility
and reliability of Coriolis flowmeters,
but the high pressures in
some of these applications may
have been prevented use of this
technology in the past. However,
the company introduced the new
high-pressure TCMH 0450 Coriolis
flowmeter for high-pressure chemical
injection applications, as well as
gas-measurement applications. It
is available in three different pressure
ratings: up to 15,200, 10,000
and 6,000 psi.
Another technology that is gaining
popularity in the CPI because
of its ability to be used in challenging
processes is non-invasive
ultrasonic transducers for mass
flowmetering applications. PIOX
S from Flexim GmbH (Berlin, Germany;
www.flexim.com) measures
from outside of the pipe. And,
since the ultrasonic transducers
are mounted onto the outside of
the pipe wall, the measuring system
is not exposed to any wear
and tear by the medium flowing inside,
allowing it to operate virtually
maintenance-free.
In
addition
to
that, there is no need to open the
pipe when installing the system,
which means there is to production,
processing or supply.
Bas
Tammen,
global
project
and international key accounts
manager, with Flexim, says: " Due
to these advantages, the use of
this flowmeter is gaining popularity
when dealing with highly corrosive
or toxic media and also in
challenging applications, such as
those with large diameter pipes.
In many of these applications, we
can reduce the cost of flow monitoring
because clamping on our
flowmeters does not require the
use of special materials since we
don't have contact with the fluid
and we don't have to stop a process
to install our technology. "
He says this is allowing users to
measure flow in areas that might
have been expensive or dangerous
to install metering technologies in
the past. Some applications might
include high-pressure processes in
LDPE (low-density polyethylene)production
and measurement of corrosive
liquids such as sulfuric acid.
The company has recently partnered
with Emerson to bring its technology
to more customers in these and
other industries looking for a lower
cost solution to measuring flow in
challenging applications.
