Level control device

The purpose of conducting this test is to investigate different methods of controlling the height of the liquid inside a tank.
Controlling a system in a general sense means that a desired quantity in a system or mechanism or machine remains at a certain value or changes according to a desirable and desired routine.
Height control is done continuously. In the continuous control system, the components of the control loop must work continuously. That is, they should be able to continuously measure the changes of variables (e.g. height) and also send continuous controller commands to the final element of the controller so that they can continuously change the value of the controller variable.
