摘要：Liquid level tanks are employed in many industrial and chemical areas. Their level must be keepa defined point or between maximum-minimum points depending on changing of inlet and outletliquid quantities. In order to overcome the problem, many level control methods have beendeveloped. In the paper, it was aimed that obtain a mathematical model of an installed liquidlevel tank system. Then, the mathematical model was derived from the installed systemdepending on the sizes of the liquid level tank. According to some proportional-integralderivative(PID) parameters, the model was simulated by using MATLAB/Simulink program.After that, data of the liquid level tank were taken into a computer by employing dataacquisition cards (DAQs). Lastly, the computer-controlled liquid level control was successfullypracticed through a written computer program embedded into a PID algorithm used the PIDparameters obtained from the simulations into Advantech VisiDAQ software.
