Flow and Level Custody Measurement - IC-73

May 30, 2014

This course is designed to acquaint users with the problems and solutions associated with the need for high accuracy transfer of liquid and gas petroleum products from supplier to customer. These needs have been brought about by major changes in manufacturing processes and because of several dramatic circumstantial changes such as: the increase in the cost of fuel and raw materials; the need to minimise pollution; and the increasing pressures being brought to bear in order to adhere to the requirements for health and safety.

This workshop is specifically tailored for any personnel who are, or will be, responsible for designing, selecting, sizing, specifying, installing, testing, operating and maintaining instrumentation related to the field of custody level and flow transfer measurement. This could include facilities, process, chemical, electrical, instrumentation, maintenance, and mechanical engineers and technicians.

You will Learn:

  • Recall the basics of fluid mechanics
  • Identify the fundamental problems related to uncertainty
  • Compare the different methods of measuring flow in the oil and gas industries
  • Describe the various methods of level measurement
  • Compare the different methods used to derive strapping tables
  • Evaluate the different custody transfer standards in use today
  • Contrast the methods used in flow calibration
  • Identify the different types of prover systems
  • Explain the methodology used in truck custody transfer
  • Examine the challenges regarding pipelines
  • Describe the basics of leak detection
  • Analyse the methodology for monitoring and controlling production losses
  • Evaluate a variety of API standards
