Differential Flow Rate Strict Monitoring
Standard

• Since cooling water leakage is very important
  factor to monitor, very small leakage must
  strictly be measured.

Alarm Analyst - Correlation analysis
Alarm Analyst R20

• Correlation Analysis-
• Easy to build Knowledge-Base alarm event model
  unique technology
• From alarm event historical logs, Correlation
  Analysis extracts -
• Event groups consisted of the alarms and the
  operation actions in a process upset
• Propagation path
• Source origin
• Nuisance alarms
• Total counts in Alarm Event group
• Information about Alarm Event group structure
• Cause Effect relationship
• Cause of alarm flood or complex operation is
  estimated using order of events occurrence.
