Korsnäs Gävle uses Emerson
Process Management’s
Smart Wireless conductivity
and temperature transmitters
to collect critical leak-detection
monitoring data at its board
and paper production unit at
Gävlebukten, Sweden. The
improved monitoring lets the
company verify its
compliance with
environmental monitoring
legislation.

Water from heat exchangers
at the plant is monitored prior
to its return to the sea. Small
internal leaks may result in
the discharge of hazardous
chemicals into the local
environment. Any leak of
acids, bases, or salts will raise
the electrical conductivity of
the water and is detected
using a conductivity sensor.

The Smart Wireless
solution that Korsnäs Gävle
installed includes a Rosemount
Analytical 6081-C transmitter
connected to a conductivity
probe. The transmitter sends
data via a Smart Wireless
Gateway to the control and
data acquisition systems,
where it is used to ensure
compliance with the
environmental monitoring
legislation.
