An intensive professional development training course on

Gas Flow Measurement

The Art and Science of Gas Metering Instruments

Why Choose this Training Course?

This intensive five-day course covers the fundamentals of Gas Flow Measurement including how to sample, analyze, and determine measurements rigorously. The slightest error in gas flow measurements, during transfer between supplier and customer, may cost millions of dollars yearly.

Gas flow measurement is used for inventory accounting, process plant mass balances, loss prevention, and regulatory as well as fiscal reporting. From the production site to the point of consumption, accurate measurements are vital. Accuracy and precision are both crucial and mandatory, particularly where fiscal custom transfer duties are to be imposed. Measurement equipment need to be selected, installed, calibrated, operated, inspected and properly maintained whilst at the same time the results must be processed and accurately accounted.

The importance of clear and precise specifications, in order to specify, procure operate and troubleshoot these instruments, both to service the needs of the company and also to meet the relevant requirements of the regulatory authority, will be taught.

This training course will feature:

Each delegate will achieve a detailed understanding of the following theoretical aspects:

  • Appreciate design criteria and importance of accuracy in gas quantity and quality measurements
  • Basics of measurement uncertainty
  • Understand measurement concepts and types of error
  • Understand the basic concepts, principles of operation and equipment used for typical liquid/gas metering systems, meter proving, sampling and analysis
  • Understand typical operations, control functions and record keeping requirements for crude liquid/gas metering systems


What are the Goals?

The course comprises of the basic flow measurement theory of gases in pipes and conduits. The effects of pressure and temperature on flow meters and on flow measurements are explained in detail, and an insight into fluid dynamic terminology is provided, e.g. Reynolds numbers.

Particular emphasis will be given to differential pressure generating flow meters; orifice plates, Pitot tubes and Venturi meters, Coriolis, as well as other types of flow meter. The advantages and disadvantages of each type will be fully explained as well as the important interaction between flow measurement and gas sampling.

By the end of this training course, participants will be able to:

  • Specify, select and procure the right type of flow measuring device for the intended application
  • Learn the theory behind a variety of gas flow measuring devices
  • Appreciate the inner workings of gas flow measurement devices as well as how to maintain and troubleshoot them
  • Understand issues related to reliability, reproducibility and measurement accuracy
  • Understand the legal and commercial requirements for liquid/gas metering
