Measurements of liquid level in vessels, tubes and tanks are often encountered in the industrial world. The problem that occurs at level control is unstable flow rate supply cause response time achievement of desired level to be slow, even more when setpoint level change. This problem is solved by designing a PID controller combined with Gain Schedulling. The combination of PID and Gain Schedulling solves the problem of achieving the setpoint. However, achieving setpoints takes a long timeAlso when disturbances occur pid gain scheduling has not been able to handle it firmly. To solve the problem, a sliding mode control (SMC) controller is selected to handle time response issues. The simulation results show that the combination of hybrid controller PID gain scheduling and sliding mode control able to reach set point with fast time. The test results obtained from three setpoint level changes of 25%, 50%, 75%, and 100%. With the rise time value obtained sequentially that is 225.1138 seconds, 439.5982 seconds, 413,3095 and 537,1012 seconds of the total simulation time of 2500 seconds
