Liquid level control plays a crucial role in the industrial process control for the accurate results of the output (product). The fuzzy logic controller is the most commonly used method because of their accuracy and ease of design rules for nonlinear process control in the industrial application. The main objective of this paper is to show how liquid level of a couple tank system can be controlled by the fuzzy logic controller by using the LabVIEW software. Liquid level controller via is interfaced with Arduino Uno board using LIFA to see the controller performance. The output of the controller is observed by one LED and buzzer.
