Flow Measurement And Custody Transfer Training

Explore the principles of flow measurement, custody transfer systems, calibration techniques, and industry standards. Gain practical knowledge for accurate flow measurement and custody transf

Flow is the most commonly measured variable in processes, whether the process is continuous or batch in nature. Many processes are controlled by varying the flow: reflux to a pipe or fractionator column, heating medium to a reboiler, fuel to a fired heater, or the discharge rate from a separator. Accurate measurement and control of flow are also critical from an economic point of view since practically any fluid that flows through a plant has a price tag. Control of flow is generally quite straightforward and easily accomplished; usually, the difficulty lies in selecting the proper measurement device.

In this highly intensive training course, participants will gain a sound understanding and extend their knowledge of Flow Measurement and Custody Transfer systems, principles and types and how to assess their impact on the strategic and tactical aspirations of the company.

Flow measurements can be grouped into four categories: Basic measurement for process monitoring and regulatory control; Unit material balances; Accounting information for custody transfer (product sales); Information required by regulatory bodies for permitting.
