Flow Measurement and Custody Transfer

Custody Transfer defines the point at which ownership changes hands for the process product being measured. This transfer is unique among flow-meter applications since money changes hands and accuracy requirements are higher than they are for most other applications. The custody transfer system must generate detailed and indisputable cargo reports, based on accurate flow measurements and calculations.

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

This training seminar will highlight:

• The laws governing fluids and gases
• Important principles of flow-metering including accuracy and repeatability
• Main types and applications of Flowmeters with emphasis on custody transfer
• Flowmeter proving and calibration techniques
• Custody transfer principles and applications

This training seminar 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.

At the end of the seminar, the participants will:

• Have a sound understanding of relevant fluid and gas Laws that are needed for the use of flow measurement devices
• Understand the main requirements of custody transfer systems
• Appreciate the main requirements of flow measurements including accuracy and repeatability
• Be knowledgeable about up-to-date flow measurement meters including differential pressure (DP) measurement, turbine meters, positive displacement meters, Coriolis flow measurement, Magnetic and ultrasonic flow measurement
• Gain the ability to determine if a metering system is adequate for the purpose, select appropriate custody transfer metering systems and identify potential problems
• Learn about the principles and applications of Multiple meters/meter runs, Flow computers, Quality systems, Calibration, Meter Runs, Proving and Supporting Automation

The Flow Measurement and Custody Transfer training seminar combines structured and focused presentations and discussions of topics covered with relevant examples and question & answer sessions to maximise the benefits to the participants. Relevant computer simulations and videos will be used to emphasise the main topics

Participants will be provided with comprehensive hard and soft copies of the seminar notes and soft copies of all presentation material. These will be very valuable for detailed study and future reference.

• The company will achieve improved and optimised control of its custody Transfer and flow measurement operations.
• Optimised process selection criteria will increase efficiency and Financial Performance and result in Fiscal Savings. This will be brought about by more accurate measurement techniques and more robust Custody Transfer operations.
• Improved competencies will result in higher staff productivity and effectiveness.
• The organisation will be able to generate detailed and indisputable cargo reports, based on accurate flow measurements and calculations.

• Participants will gain sound and practical understanding and extend their knowledge of Custody Transfer and Flow Measurement systems, principles and types, and how to assess their impact on the strategic and tactical aspirations of the company.
• Participants will have the necessary information and confidence to conduct reviews of flow measurement systems and the ability to report to management on the status of the custody transfer systems in place and methods of improvement.
• Participants will be able to minimise loss and increase Fiscal Gains, through the correct selection and operation of flow measurement systems that are related to Custody Transfer.
