Gas Measurement: Equipment and Calculations
e-Learning
About the eLearning Course
In this course, you will learn about differential pressure within a flowing fluid. the course defines and discusses rate, velocity and critical flow of a fluid. You will learn about the basic operation of, and the method of measuring with pitot tubes, permanently installed pitot tubes, calibrated choke nipples, orifice well testers, and critical flow provers. We also cover topics on various types of meters, as well as proving with test meters, with low-pressure flow provers, and critical flow meter proving.
Target Audience
Operations personnel who require a fundamental understanding of knowledge to operate and maintain facilities. Also suitable for maintenance and technician personnel whether new to their roles or seasoned experts looking to enhance their skills.You Will Learn
