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.

This training course has been specially developed for personnel that are required to work with and or are involved in selecting, maintaining, troubleshooting and calibrating gas flow measurement systems. It will also be of great benefit to personnel who are involved in sampling, analysis & custody transfer operations that require specific knowledge to conduct measurements & calculations in flow systems.

This training course is suitable to a wide range of professionals but will greatly benefit:

• Production Supervisors
• Instrument Supervisors
• Graduate Engineers
• Process Engineers
• Production Engineers
• Metering Engineers & Technicians
• Instrument & Analyser Technicians
• Personnel who witness or audit natural gas measurement

This course will utilise a variety of proven adult learning techniques to ensure maximum understanding, comprehension and retention of the information presented. This includes interactive sessions with questions, discussions and problem solving under supervision along with syndicate exercises. It will be conducted as an interactive workshop that encourages participants to share their own experiences and apply the programme material to real-life situations.

The course will be reinforced by a learning mix that includes, lecture style presentation, short videos, open discussion, case studies, simulations and syndicate exercises.
