The first H2 flowmeter certified
for dispensing applications
The TCMH 0450 High Pressure TRICOR
Coriolis flowmeter (photo) is
said to be the world's first MI-002 /
OIML137-certified Coriolis flowmeter
for hydrogen dispensing applications.
By securing this certification,
the TCMH 0450 can now be used in
custody-transfer applications - specifically
in H2 dispensing stations for
the fast-growing H2-powered vehicle
market. By using the TCMH 0450
flowmeter, companies can sell H2 fuel
to end users with taxation. Without a
certified fuel dispenser, the taxation
of H2 is not possible. Because H2 is
so light, flowmeters in hydrogen dispensers
must operate at high pressures
(up to 1,050 bars), and tolerate
extreme and rapid temperature
changes. - KEM Küppers Elektromechanik

Dual sensor operation with
four-wire sensor connection
The Sitrans TH320/420 and
TR320/420 HART temperature transmitters
(photo) cover a wide range of
sensor types suitable for mounting in
sensor-head and rail mounting. They
feature high availability of the measurement
signal and ease of use. Due to
the safety integrity level (SIL) 2/3 certification
according to IEC 61508, these
temperature transmitters are particularly
suited for safety-critical applications.
The devices also have a large
number of country-specific explosion
protection certificates for all zones.
They provide reliable results, even
under extreme conditions down to
-50°C. Main application areas include
industries such as chemical, oil and
gas, marine and power generation. -

Free-standing separators that
are modular and flexible
The new SKT separator models (photo)
are square, made of plastic, glass-reinforced
polymer, steel or stainless steel
and can be optionally delivered with
one or more flocculation tanks, agitators
and rabble rakes and all necessary
peripherals. Expansion by new modules
is possible at any time. The modular
design allows flexible responses to
changes in process requirements. In
comparison to conventional sedimentation
tanks, the free-standing separators
require a much smaller installation
space - space savings of up to 90%
are possible. Further savings result
from lighter, smaller foundations and
lower transport, installation and maintenance
costs. Since sludge draining is
done by hydrostatic pressure, usually
no pumps are required, which helps
save energy costs, says the company.
Inside the tank, a TUBEdek parallelplate
pack ensures a reliable separation
process. The great number of
equidistant sedimentation levels of the
chevron-shaped channels provides
the system with a high hydraulic capacity
and supports sludge removal.

Mixer panels with additional
UL and NFPA certifications
This company recently completed the
qualification to self-certify its touchscreen
purged panels (photo) as
meeting the standards of Underwriters
Laboratories' UL-698A Code and
the National Fire Protection Association's
NFPA-496 Code. UL-698A covers
industrial control panels designed
for hazardous locations, including
the use of intrinsically safe barriers.
NFPA-496 standards relate to purged
and pressurized enclosures. Purge
systems are an alternative to traditional
NEMA 7, 9 explosion-proof enclosures
and are suitable for most all
hazardous locations, including: Class
I, Div. I & II for gas and vapor environments;
and Class II, Div. I & II for
dust environments. Purge panel enclosures
can be NEMA 4 carbon steel
or NEMA 4x stainless steel, depending
upon the requirements. The ability
to self-certify enables this company
to offer UL and NFPA labels on explosion-proof
panels at a lower price,
without the additional cost for a thirdparty
inspection. The new certifications
are in addition to UL-508A (nonhazardous
control panels), which the
company has maintained for more
than a decade. - Ross Systems and
