There are two types of control systems namely: 1  Open loop control systems (non-feedback control systems) 2  Closed loop control systems (feedback control systems)
Taking measurements for control processes has the most variety when discussing types of chemical process control. The combination of operations, flow types, measurement tools, and control systems all contribute to determining the final type of chemical process control.Engineers use recorded data and math tools to predict the design of a chemical process control and determine ways to improve those already in use.Ad.he combination of operations, flow types, measurement tools, and control systems all contribute to determining the final type of chemical process control.
