Application note

Panametrics keeps the mill rolling
Benefits:• Easy to set up and retrofit• No process interruption
for the clamp on• Powerful reputation in
ultrasonic flow measurement• Proven reliability over the years• Strong local support

A large steel plant in Eastern Europe with an annual production capability of
4.5 million metric tons of steel, employing in excess of 11,000 people has been
benefiting from Panametrics technology since the early 1990s.
Panametrics has a strong track record across steel plant applications. In thisinstance, the customer has deployed many Panametrics’ ultrasonic flowmetersacross various applications, and is a good illustration of their durability, quality andcost effectiveness.
Specializing in developing ultrasonic technology that remains accurate andreliable under harsh conditions, it is not uncommon that meters run for 15 years ormore. More often than not, they are replaced, not because they are broken but due
to evolving communication and diagnostic capabilities or because the layout of afactory has changed.
Working with the steel plant customer in Eastern Europe, Panametrics has supplieda range of technology that has helped optimize its operations, providing upgrades
only when cost effective to do so.

AT600 replaces AT868

Picture 1. Replacement of AT868 flow
meters on the Coke oven battery.

A total of four AT868 water flow meters were replaced in 2021, almost 20 years
after they were implemented. These meters still worked well but as the piping
was replaced, the customer decided to replace the units with the new AT600
technology. This provides the customer with even more modern flow data.
Pictures 4 and 5 show a diagonal WT transducer installation on a DN1000 (40”)
cooling water line that had the AT868 electronics replaced by AT600. The WT
transducers still show healthy diagnostics and have remained in place.

AT600 Clamp on C-RS installed from2002 still works fine and kept in place.

The old magnetic flowmeter from another vendor had erratic readings resulting
in incorrect pump control. While a new permanent solution was sourced from thesame vendor, a Panametrics clamp on flow meter was temporarily installed, sothat the customer did not need to halt operations. The customer subsequently
confirmed that the clamp on measurement exactly matched measurement fromthe new installed magnetic flow meter.

GM868 replaces like for like
For a Coke Oven Gas (COG) chimney,
two new GM868 units were installed in
2021 to replace equipment dating backto 2007 and 2008.
Both chimneys were originallyequipped with long path tilted
diameter solutions. Although replacing
like for like, Panametrics recommended
changing the setup of the ultrasonicpath. The customer agreed andreplaced the tilted diameter to bias 90
which has proven to provide a higher
immunity to gas wetness and dirt.

XMT1000 replace 6468
The 6468 electronics (Picture 8) thatwas installed in 1996 was replacedby five PanaFlow XMT1000 UltrasonicFlow transmitters in 2021. While theWT wetted transducers still worked
well, the 6468 electronics wereobsolete after 25 years of service. The
customer now benefits from evenbetter accuracy, communication anddiagnostic performance.

Total installed base:• AT600: More than 30 installations
since 2015 on water lines• AT868: 3 remain inservice on water lines• XGM868 + BIAS90 T5: 9 installed oncoke oven gas, fuel gas and highpressure bidirectional nitrogen gas• GM868 + TD T5 180: 6 meters,
the largest on a DN2000 (80”) forblast furnace gas from year 2000
• MV80/82: in total 16 on various
utility applications including:water, steam, air, nitrogen

Pleased with how Panametrics hashelped optimize its operations since
the early 1990s, the customer continues
to explore other opportunities for new
measurement points and upgrades
to improve efficiencies and save costs
using Panametrics technology.
