Prior Use or Certified – Rely on Micro Motion
Micro Motion Coriolis meters and manufacturing processes have been certified by Exida® Certification S. A. to IEC 61508 for use in SIL-2 and SIL-3 applications. As the technology leader, Micro Motion offers customers the highest accuracy Coriolis meters available, with safety certification to boost safety and plant availability.
Micro Motion has certified Coriolis meters to help you meet your responsibility for ensuring your plant complies with IEC 61511, Safety Instrumented Systems (SIS) for the process industry sector. We recognize that, even with safety as a top priority, you still need to maximize profitability, availability, reduce costs and maintain flexible production levels. Is all this possible? With Emerson Process Management, all this is possible -- and more.
Prior-Use Strategy
For those plants choosing the prior-use methodology, demonstrating a history of safe operation is paramount. As the world’s most preferred Coriolis sensor, Micro Motion offers millions of safe operations hours supported by third-party documentation. In fact, Micro Motion FMEDA scores are the best of any Coriolis vendor and offer unmatched capability. In fact, scores were so high that our standard product qualified as a certified device.
Certified Strategy
When your application requires products certified to IEC 61508, Micro Motion flow and density technology stands alone. Model 1700 and 2700 transmitters are Exida certified to IEC 61508 for use in SIL-2 and SIL-3 applications.
Coriolis Benefits in Safety Strategy
- Micro Motion Coriolis meters have Meter Verification diagnostics that extend proof test intervals
- Coriolis meters have no moving parts, and resist plugging or fouling
- Coriolis meters are inherently bi-directional, superb in back flow detection applications
- Coriolis meters are not damaged by abnormally high or pulsating flow rates
- Multiple process variables provide real-time information regarding the health of the process
- Micro Motion Coriolis meters have inherently high turndown ratios for flow measurement providing an excellent diagnostic of ESD valve shut-off performance
- Density accuracies to +/-0.0002 g/cc are available making the meters an excellent choice for measurement or control of product concentrations or quality
- Precision totalization enables accurate measurements for the storage of Propanes or Butanes
- Mass flow accuracies to +/-0.05% of rate are perfect when charging reactors with expensive catalysts
- Low pressure drop helps with gas feeds to furnaces
- Ability to handle high viscosities such as fuel oil feeds to burners
- Detection of dangerous composition changes, such as critical feed of reactor catalyst flows into exothermic reaction, via density/concentration measurement
- No leak points for fugitive emissions when handling dangerous gases like Phosgene or Chlorine
