For most of the Industrial and pharmaceutical applications precise level control of tanks are necessary. When precise control of level is achieved much good quality of product can be yielded. To achieve better results it is needed, to implement a robust controller than conventional PID controller. In this paper a Split-Range Setup is prototyped and is used to control level in a tank. With this split-range setup the following controllers such as PID Controller, Fuzzy Logic Controller and Sliding Mode Controller (SMC) were designed and implemented. The whole control is programmed and implemented in LabVIEW (Laboratory Virtual Instrument Workbench) software. This software is based on graphical programming technique. By application of these controllers the best suited one is suggested considering the characteristics such as time taken to reach the setpoint, Settling time, peak overshoot etc.
