Cause and effect can sometimes be predicted by observing abnormal behavior even when the behavior is within specifications. Operators log equipment data and inform shift management when specifications are exceeded or when unusual equipment behavior is noted. Engineering establishes trending when patterned behavior is noted. Rotameter sample flow failures are too erratic to establish a cost effective preventive maintenance program. Predictive maintenance establishes a method to predict imminent failure based on symptoms that may be displayed during normal (within specification) operation. Operations and Engineering will continue to assess abnormal equipment behavior that may be within specification, and implement prediction methods, like trending, when applicable. Maintenance will implement annual rotameter inspection to aide in rotameter operational assessment.
