Abstract
This paper describes the development process and testing procedures of a reduced scale plant reproducing a continuous process. The fluid level within three communicating vessels is controlled using the PID (Proportional Integrative Derivative) technique. The vessels interconnections as well as the turbulent flow through the pipeline make the process to be controlled non-liner, as expected in several real applications. Three vessels, one horizontal cylindrical, one conical and one squared base prismatic compose system. Pressure sensors are utilized to monitor the fluid level in the tanks and to provide feedback to the PID control block embedded in a PLC (Programmable Logical Controller), which in turn, sends analog signals to an automated valve, built from a servomotor and an ordinary ball valve. The automated valves, then, manipulate the flow moving in and out the vessels, and hence, controlling the fluid level. In addition, a frequency inverter - Power Flex 70 AC – is employed to manipulate the nominal maximum flow the system will work with. A plant model is proposed and the bill of materials employed to build it is described across the steps of the development
