For example, if the water flow in a pipeline suddenly increases, a chlorine dosing system using ratio control will immediately add more chlorine to. Ratio control can keep all the units in balance. A simple example of ratio control is in the production of paint, where a base liquid must be mixed with one or more pigments to achieve a desired consistency and color.

Ratio Controller Example Instrumentation And Control Engineering Control System

In this design, the fuel set point, spw, comes in as firing demand from a. A change in feed to one unit operation has a widespread ripple effect on downstream unit operations Ratio control systems are a crucial component in various industrial processes, ensuring that the ratio of two or more process variables is maintained within a desired range

F2 = kf1 (9.25) where k is a specified ratio which may have been calculated as an optimal ratio from a process model

One example is the calculation of the ratio between oil inflow and air inflow to a. A classic example of ratio control is the blending of an additive into a process stream Ratio control maintains a constant proportional relationship between two or more process variables, typically flow rates One flow is the “master” (wild/uncontrolled), and the other is the “slave”.
