Tank Farm Automation for United utilities, UK is an project which Applied implemented for facilitation of a functioning of a tank farm. The operations of a tank farm is to collect oil from tankers and store into huge storage tanks used oil and dirty oil. The store Oil is then purified and transferred to a clean oil storage tank for re-distribution and tankers collect the same. The entire operation were implemented by Applied using a Rockwell Automation System – Compact Logic PLC over distributed IO and RSView Scada. Flowmeters, Pumps, Ac Drives, Thermocouples, Differential Pressure Sensors, Vacuum transducers, Pneumatic activated vales with feedback were integral part of this project.
