The importance of this book is emphasized on the fundamental concepts and principles of various types of control valves and intro the LABVIEW environment of industrial process. Control valves are an increasingly vital component of modern manufacturing around the world. Properly selected and maintained control valves increase efficiency, safety and profitability. The purpose of LABVIEW is to create graphical programming and virtual instruments. LABVIEW contains a comprehensive set of tools for acquiring, displaying and storing data, as well as tools to help you troubleshoot code you write. The use of LabVIEW software development platform combined with data acquisition cards and Datasocket communication protocol achieves long-range data transmission. Comparing with the traditional data acquisition and processing system,it has the advantages of cost-effective, high universality, easy-to-development, high portability and so on. This can make the users who do not have much experience free from the heavy programmers, make the users invest more effort in the testing, data analysis and processing.
