a) Pressure b) Level c) Flow d) Temperature

Pressure: If the load change is minimum, then a proportional controller is suitable. If a frequent load change is expected then a Proportional + Integral controller is preferred.

Level : Normally a proportional controller is preferred.

Flow: Proportional + Integral controller is preferred

Temperature: Proportional + Integral + Derivative controller is preferred
