Oil and Gas Measurement & Control

Introduction

A flow meter is a measuring device for determining the flow rate of a fluid,

normally in a pipe, e.g., the flow of natural gas, or oil, or waste water. With

these instruments, an immense amount of money is controlled, and thus,

flow metering has an enormous economical significance. It is reported in

relevant Publica tions and J ournals that the c osts that are controlled by

flow meters are estimated as being worldwide of the order of 10,000 billion

US dollars per year. One percent uncertainty in the measurement wouldstill represent a considerable value. Flowmeters affec ts greatly the

accuracy of processes, and control systems , plus its critica l application

when comes to custody type of measurements . In this course delega tes

will have the opportunity to learn about the different types of Flowmeters,

their design, operation, performance and application. This will help

selecting the appropriate Flowmeters for the application. Limitations, and

problems associated with each type of flowmeters will be analyzed

thoroughly, thus enabling one to troubleshoot and correct the error that

might occur during measurements . Flowmeters reliability can not be

assured unless a periodic calibration and maintenance program been

adopted. Calibration methods and appropriate provers for different type

of meters will also be discussed in this course.

Who should attend the course?

This course is designed for mechanical and operation engineers and senior

technicians who are responsible for specifying, selecting, operating, and

troubleshooting a nd maintaining flowmeters.

Course Methodology

A highly interactive combination of lec tures and discussion sessions will be

managed to maximize the amount and quality of information and knowledge

transfer. The sessions will start by raising the most relevant questions, and

motivate everybody find the right answers. The delegates will also be

enc ouraged to raise their own questions and to share in the development of the

right answers using their own analysis and experienc es. Tests of multiple-c hoice

type will be made ava ilable on daily ba sis to examine the effec tiveness of

delivering the c ourse.
