A filling volume of 15l gives rise to a control deviation of 211 – 151 = 61
Because our actual value lies outside the bandwidth, the control will control the flow at 100%
i.e. at 4l / minute
The supply quantity (actuating value) is calculated from the control deviation
(set point value – actual value) and the bandwidth.
Actuating value = (control deviation / bandwidth) x 100
The table below shows the response and therefore also the limits of the P-control

The last line indicates that the filling level cannot increase any further, because the flow
allows only the same amount of water to flow in as can flow out through loss.
The result is a permanent control deviation of 11 and the set point value can never be reached.
If the loss was 1l higher, the permanent control deviation would increase by the same amount
and the filling level would never exceed the 19l mark.
