Do you encounter issues related to flow measurement accuracy in your plant?
We are often faced with questions such as – am I getting correct measurement from this flowmeter? Is it time to calibrate[1] this meter? Did the corrosive application change the calibration factor of my flowmeter?
As known very well, ensuring that flowmeters are performing accurately is essential for managing product quality, reducing waste and rework, providing a safe work environment, and to providing confidence that you have measured exactly what was delivered.
The accuracy of your device is another key component that is essential for plant managers. How often is an instrument’s accuracy verified?‐ What if the measurement is off for a week, a month, or a year? What are the consequences of failing a quality audit, or reporting an incorrect number to a regulating agency? Is there a safety risk to employees if a leak is not detected or a tank is overfilled? Have you encountered these challenges in your plant?
To assist you in identifying whether a flowmeter needs to be calibrated or how often it needs to be calibrated, Emerson has developed a comprehensive in‐situ diagnostic technology called Smart Meter Verification. I am glad to share this guide, which is intended to help you determine the periodicity of calibration of a Coriolis flowmeter. The controlled conditions at an Emerson Flow Calibration Center provide the best possible assurance that your meter is performing to its original specifications.
Moreover, in order to meet regulatory requirements or to meet Quality Assurance requirements, an ISO17025 calibration may be required, which is typically applied to flowmeters used in Custody Transfer applications.
These series of Global Calibration videos “PFS7K Calibration System”, “SCC Calibration Area”, “ISO Accredited Calibration Centers” and “Wrap Up”, will help explain how Emerson establishes and maintains traceability of its Flow Calibration Centers across the globe to international standards.
1. Calibration is defined as a comparison between a meter’s readings and a known reference in order to establish a relationship between measured and actual.
