Data Validation Software – Overview vali::tool automatically detects, marks and (optionally) corrects untrustworthy data. It detects outliers, and noise and checks for discontinuous data. It ensures only high-quality data is fed into the event detection module. It also provides the user with indications on sensor maintenance requirements and automatic detection of malfunctions. Data Validation Software – Features Provides self-adaptive, self-controlled data validation in real time Ensures sensitive and reliable alarm limit setpoints for process control Analyses noise, outliers and other combinations in real time Detects any malfunction at an early stage Considers user interventions in real-time Application-specific training period considers normal fluctuations of individual water matrix and typical process dynamics Reduces false alarm rates Configurable auto-correction of data based on threshold, outlier and noise analysis
