This technical guide explains how Coriolis flow meter technology delivers the precision required for custody transfer operations in petroleum and natural gas applications. You will gain practical insights into Coriolis flow meter selection criteria, installation best practices, and how to maximise measurement accuracy in your specific operating conditions.
Custody Transfer Fundamentals: Why Accuracy Matters
When you're managing custody transfer operations, measurement accuracy directly impacts your bottom line. At these critical points where product ownership changes hands, even minor measurement errors can lead to substantial financial discrepancies. Industry standards demand ±0.1% accuracy or better, making the Coriolis flow meter your most reliable choice for fiscal measurement.
How Coriolis Flow Meter Technology Delivers Unmatched Precision
The Coriolis flow meter measures mass flow directly using the principle that fluid flowing through vibrating tubes generates Coriolis forces proportional to mass flow rate. This fundamental approach eliminates the compensation errors you encounter with volumetric technologies, providing you with more reliable custody transfer data.
Key Benefits of Coriolis Flow Meter Technology
-
Direct mass measurement eliminates temperature and pressure compensation errors
-
Simultaneous density measurement for quality verification with each Coriolis flow meter
-
Minimal sensitivity to installation effects and flow profile changes in Coriolis flow meter systems
-
Long-term calibration stability reduces your maintenance frequency with Coriolis technology
Crude Oil Applications: Managing Complex Fluid Properties
In your crude oil transfer operations, you face variable densities, viscosities, and potential entrained gases. Modern Coriolis flow meter technology with advanced signal processing helps you maintain measurement integrity despite these challenging conditions, providing consistent accuracy when it matters most.
Optimising Your Coriolis Flow Meter Installation
-
Ensure adequate pipe supports to minimise mechanical stress on the Coriolis flow meter
-
Implement comprehensive grounding systems for Coriolis flow meter measurement stability
-
Consider Coriolis flow meter orientation to prevent gas accumulation in the tubes
-
Install appropriate filtration to protect your Coriolis flow meter against solids contamination
Natural Gas Liquids and Dense-Phase Applications
For your natural gas liquids and dense-phase natural gas operations, the Coriolis flow meter provides significant advantages over traditional orifice plates. The Coriolis flow meter's ability to measure mass directly gives you reliable data even when fluid composition varies, ensuring accurate custody transfer throughout changing process conditions.
Dense-Phase Measurement with Coriolis Flow Meters
When you're operating in dense-phase conditions, the Coriolis flow meter maintains its accuracy where other technologies struggle. The Coriolis flow meter's immunity to changes in fluid properties makes it particularly valuable for your supercritical fluid applications.

The elimination of measurement disputes alone can justify the Coriolis flow meter investment in many applications.
Frequently Asked Questions About Coriolis Flow Meters
What measurement accuracy can I realistically expect from a Coriolis flow meter in crude oil service?
With proper installation and regular maintenance, Coriolis flow meters typically achieve ±0.1% to ±0.15% accuracy for liquid hydrocarbons. This performance level meets the stringent requirements for fiscal measurement in custody transfer applications.
How do Coriolis flow meters handle entrained gas in crude oil streams?
Advanced Coriolis flow meters incorporate sophisticated diagnostic algorithms that detect and compensate for entrained gas content. The Coriolis flow meter provides reliable measurement and generates alerts when gas content exceeds predetermined thresholds, allowing you to maintain measurement integrity.
What certification standards should I require for Coriolis flow meters in custody transfer?
Your Coriolis flow meter systems should comply with API MPMS Chapter 5.6, OIML R117, and ISO 10790 standards. These certifications ensure your Coriolis flow meter systems meet international requirements for fiscal measurement accuracy and documentation.
What operational lifespan can I anticipate from Coriolis flow meter systems?
Given their robust construction and absence of moving parts in the measurement path, Coriolis flow meters typically deliver 15-20 years of reliable service in continuous petrochemical operations. Regular preventive maintenance can extend your Coriolis flow meter operational lifespan even further.
