Korsnas Gavle Meets Environmental Requirements Using Smart Wireless Technology
Environmental legislation required that water from heat exchangers must be carefully monitored for contamination before it is returned to the sea. Failure to comply could require production to be stopped at the plant. Monitoring electrical conductivity is a standard detection method for leaks of acids, bases, or salts since any leak is easily detected using a conductivity sensor, but the existing I/O supporting these devices was to be removed in a renovation project. An alternative way to transmit the required measurements to the main control room was needed.
A second application required Korsnäs Gävle to establish continuous monitoring of emissions from effluent in aerated basins and ponds. New sensors measuring pH, dissolved oxygen, and water temperatures had to be installed and connected to the central monitoring system, but there were no available cable runs and the closest available wired connection point was more than 500 metres away. Installing new cabling would present a considerable challenge and cost roughly €200/metre.
