Automatic In-Situ Verification Of Accuracy For CoriolisMaster Mass Flowmeters

By Frank Frenzel and Reinhard Poft

Users often question whether their measuring devices are working properly and within specified measurement accuracy. The new CoriolisMaster flowmeter models by ABB include technology for integrated online diagnosis and accuracy verification. This technology constantly monitors the oscillating meter tube within the flowmeter for erosion and coating deposits.

Self-monitoring technology avoids costly downtime needed for proof testing and provides other significant cost savings. It permits compliance with increasingly strict quality standards and legal requirements for verification of flowmeter accuracy.
