Theproposed system provides an analysis of the simulation and components required for the implementation of an automated level control system by the help of Programmable Logic Controller (PLC).Supervisory Control And Data Acquisition(SCADA) was established and the HMI was created. The proposed model can effectively supervise level control in multiple tanks. Three level sensors were used to provide the level data to the PLC. PLC used this data to take the required decisions and thereby turning ON and OFF a pump. A manual switch was also provided to override the automatic system. The SIMATIC S7-300 universal controller was used as the main decision making module. The system was implemented in SCADA to create the required Human Machine Interface (HMI). Modifications can be made by using float sensors model which would effectively provide the correct level but cost would increase and vibration of the sensor might disrupt the result, our model effectively counters those shortcomings.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
