Flow controllers are electric devices that monitor and provide feedback to control flow-rate variables as part of a process control application. They can be used in conjunction with pumps, valves, ...

Control valves are power-operated devices used to automatically modify fluid flow or rate pressure in a process system. The terms 'control valve' and 'throttling valve' are often used interchangeably ...

Compressible fluid flow through control valves will inevitably cause some form of flow-induced vibration in the fluid system. Identifying the type and cause of the vibration requires detective work.

Proportional-integral-derivative (PID) is the most common industrial technology for closed-loop control. A proportional-integral-derivative (PID) controller can be used to control temperature, ...

Just over a decade ago, an article titled, "Advanced Control Strategies Move into the Field" (Control, October 2008), highlighted three evolving trends in the process control world that would "make ...
