ABSTRACT
This introduction presents an overview of the key concepts discussed in the subsequent chapters of this book. The book is about process measurement technology. This includes meters for pressure, temperature, level, flow and a few others. The book focuses on processes running in pipes and tanks, and discusses measuring methods, equipment, installation, maintenance and, perhaps most importantly, calibration and traceability. It also focuses on measurements and the problems around mixing, moving and distributing products, and how to control and measure these processes. Almost all manufacturing processes include mixing of different components. Often a product is mixed with water (diluted) to obtain a final product with the right concentration. However, the purpose of the process can also be to create a reaction, a particular product characteristic or the right flavour or texture. In a filling process, a certain amount (portion) is pumped or transferred into a package.
