Product highlights

Highest safety thanks to reliable trace measurement In power plants, the quality of the water is a key factor in keeping the water/steam cycle free from contamination. Turbines, boilers and pipes can become corroded and encrusted if the water is not pure enough, leading to expensive repairs or even complete unit replacement. The high temperatures and pressures in the water/steam cycle and the low measuring ranges demand smart solutions. • Conductivity, pH and oxygen sensors that have been designed for trace measurement ensure that even minute impurities in the demineralized feedwater are detected. • SWAS panels (Steam/Water Analysis System) comprise all the measuring technology that is needed to monitor a water/steam cycle. The measurements are performed online, i.e. a sample of the feedwater comes directly from the cycle, passes through a temperature and pressure reduction system (sample preparation) and is then sent to the sensors and analyzers that are mounted on the panel. The sample is discarded after the measurement.
