Valves and other apparatus

Almost all practical fluids engineering problems are associated with the need for an accurate flow measurement and control. There is a need to measure local properties (velocity, pressure, temperature, density, viscosity, turbulent intensity), integrated properties (mass flow and volume flow), and global properties (visualization of the entire flow field) or to control the fluid flow using different kinds of valves. In this section some pressure are velocity measurement systems and valves are shown.
