Modern fluid flow control techniques in fluid systems that are encountered in the process and chemical industry, involve the control of flow rate; measurements of pressure and temperature; and, other quantities at upstream and downstream locations. They also involve a means for enabling the passing of maximum flow rate in case of emergency situations. Fluid movers such as pumps and compressors of various designs have their own flow control devices for regulating flow rates, pressures and in some cases, motor loads (variable speed motors or variable speed couplings). Control valves play a major role in fluid flow control. They are used for pressure reduction, control of delivery flow rates, back pressure control, pressure relief, etc.

Fluid flow measurement is the most important process variable in the operation and control of fluid transport in piping systems and pipelines. Flow control data are monitored and computerized; and line flow balances are used to check for discrepancies on hourly, daily or weekly bases. Flow measurements are done by means of some suitable flow meters: differential pressure meters, volumetric flow meters or mass flow meters. The course will cover all practical aspects of industrial fluid flow measurements, analysis of results and relevant aspects of accuracy.

Highlights of the course include:

• Principles of selecting the most appropriate fluid flow measurement for the given industrial application
• Guidance for optimum setup of measurements and obtaining accurate results
• Practical real-life examples of application of the most effective instruments for flow measurements of gases and liquids and multi-phase mixtures
• Influence of fluid properties on final results of flow measurements
• Economical issues: cost and benefit analysis in the light of monitoring a system
