This work is an extension to the earlier publication Instrumentation Fundamentals for Process Control (2001) in which the basics of instrumentation were given along with some applications of instruments and control systems to real processes. Because the present work is an extension of this latter aspect, it is therefore confined mainly to the techniques of applying instrumentation and control systems to manipulate the process to give the desired results. The topics covered in this book will expose the reader to even more actual requirements that are to be found in real process plants, as well as to some of the methods used as solutions to control them.
