Application example: Level control
The objective here is to maintain a constant level in the container.
This is carried out by means of a variable-speed pump in conjunction with a sensor for
measuring the level.
The level is determined via an analog input and sent to the technology controller. The level
setpoint is defined in a fixed setpoint. The resulting controlled variable is used as the setpoint
for the speed controller.
