PCA for Processing Tank Using PLC

Abstract

In this work we are going to implement the automation for a process tank to control the power variable like temperature, level and product mixing by measuring and controlling the flow ratio. Here we are going to arrange the magnetic flow meter for flow measurement and gauge type level transmitter for level measuring purpose. RTD sensors are used for temperature measurement purpose. Their will be two fluids which will flow through the respective valve to the open tank according to the predetermined ratio, up to the predetermined liquid level measured by level transmitter. Once this level is reached the supply to the heating coil will be ON and the fluid is heated up to certain desired temperature which is sensed by RTD. When the fluid reaches the predetermined temperature slushing will start and the command will go to agitator and then it is pumped out by the VFD operated motor. All these operation sequence logics will be programmed in ABB PLC and the programming tool is ABB Automation Builder. The total operation can be monitored, controlled through ABB SCADA
