Paper mill's smart way to collect data

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.
