Course Overview:

This Training course will familiarise process, instrumentation and custody transfer engineers with the procedures and practices involved in the choice of flowmetering systems and their associated supporting equipment. It will address these points in relation to both single- and multi-phase flows and will give guidance on the optimum commercially available flowmeters through a detailed comparison of their relative merits. Flowmeter calibration is crucial to these topics.This  training course also covers the related issues of level and tank measurement as well as lease automatic custody transfer and truck custody transfer, leak detection, loss control and monitor and control production losses.

Course Objective:

By the end of this training participants will be able to:

• Apply an in-depth knowledge to the topics of liquid and gas flowmetering and custody measurement as well as to the fluid mechanics of pipe flows
• Assess flow measurement uncertainty in terms of the actual flowrate
• Define and classify the various regimes of multiphase flow measurement and to understand the relative attributes of the main industrial multiphase flowmeters in the determination of flowrate and quality
• Understand the various types of flow calibration, metering system and provers including static and dynamic measurement, meter proving, prover loop and custody transfer
• Carry out tank measurement and tank calibration methods and to calculate net sellable quantities
• Explain in detail the different types, methods and techniques used in lease automatic custody transfer and truck custody transfer
• Apply the various API standards applicable to custody measurement
