Flow control is indispensable in biological, chemical, food and manufacturing processes or for analytical purposes. In these process applications, it is obviously necessary to supply fluids (gases, liquids or vapours) in a controlled way – which is essentially the definition of flow control. Accurate flow control will improve final product quality, improve process understanding by investigating varying process flows and may speed up process steps. Ultimately, the flow control will improve process economics. To this end, flow control devices or ‘flow controllers’ are used. Read more
