A large number of researchesare conducting throughout the world to find optimum and most cost effective systems. In these researches, instruments measuring liquids and control systems are taken very important place (Mohammad, 2009.). Using this technology it indicates liquid capacity and control liquid automatically. Results two weeks industrial visit and I have seen this issue at Palwatta sugar factory & distillery plant use manual capacity level measuring techniques (Figure 2) or mechanical systems (Figure 1) to measure tanks liquid stock. These manual systems need additional human resources and mechanical systems to overcome the errors due to the friction of pulleys and ropes. Because of these issues inaccurate readings are obtained.enScience and TechnologyTechnologyIndustrialIndustrial AutomationComputer ScienceOther
