Experimental setup on level control system

This paper represents the experimental setup on the level control system which is called as quadruple/multivariable tank system. The setup consists of four experiments: single capacity, interacting, non-interacting and quadruple/multivariable tank system. Here, the ultrasonic sensor is used to control the level. The setup is interfaced with Arduino UNO (ATmega328) with its programming logic which is act as a controller. The obtained results are compared with theoretically and practically. Based on the performance of the system it found satisfactory for various settings.
