OverviewCustody Transfer, also known as Fiscal Metering, occurs when fluids and gases are exchanged between parties. Payment is usually made as a function of the amount of fluid or gas transferred, so accuracy is important since a small mistake in measurement can add up, leading to financial exposure in custody transfer transactions.In recent years this importance has grown, not only because of its widespread use for accounting purposes due to escalation in material values but also because of its application in several other aspects of upstream and pipeline operation such as leak detection systems and loss/gain balance. All of these applications constitute key elements for the operator who wants to maximize pipeline efficiency and requires a very strict correlation with accurate and reliable flow measurement.This programme will introduce to the participants on the various kinds of flow metering systems, the flow measurement principles, measurement methods for a well-rounded short education throughout the 4-day event.
