The following questions related to the practical control aspects for each problem. Consider how best to demonstrate/describe how the components of control (sensors, logging, controllers, actuators, power, manual components, and procedural aspects) may be the connected. Diagrams should show how control loops are connected. 4. A chlorine dosing system (0.5% NaOCI) is needed for drinking water to ensure it is sterilised during pipeline transport to a residential grid. As an engineer, you must design the control system to maintain a target concentration 0.5 ppm of dosant in the drinking water, despite varying fluid flow (to accommodate daily fluctuations in drinking water usage and also process issues). The target cannot exceed 5 ppm for drinking safety and should not be maintained at low levels (below 0.2 ppm) for very long. a) Use a diagram to describe how your design. (2 marks) b) Describe the control structure/s within your circuit. (1 mark) c) Describe the safety features of your circuit. (1 mark)
