Pelatihan Gas and Liquid Flow Measurement and Custody Transfer

Gas and Liquid Flow Measurement and Custody TransferTransportation companies the ones who own the tankers, railroad cars, or pipelines also get paid for the amount of materials they move. Companies that push oil or gas through pipelines, for example, may operate on slim margins, so they want to know exactly how much of the oil or gas transported is involved. In addition, greenhouse gas emissions and CO2 trading are emerging applications, where accurate Flow Measurement is needed.Hence, Custody Transfer defines the point at which ownership changes hands for the product being measured.

The custody transfer system must generate detailed and indisputable cargo reports, based on accurate flow measurements and calculations.

What makes custody transfer unique among flow-meter applications is that money changes hands and that accuracy requirements are higher than they are for most other applications. Hence, Custody transfer systems are more than just flow-meters and they represent a combination of highly engineered flow measurement systems for the intended application.Custody transfer metering requires exceptional accuracy, repeatability, and auditable values.

OBJECTIVES

* This course introduces participants to a variety of flow measurement technologies and systems that are used custody transfer applications, and gain an understanding about how measurement systems can work properly and accurately
