• True

• False

select all the process variables that can be sensed and feedback to the controller

• Pressure

• Temperutre

• Flow

• Compositions

• Level

there are a lot of controllers on your smartphone

• True

• False

the following order from the slowest to the faster sense of process variables is correct?

1. compositions

2. level

3. flow

4. temperate

5. pressure

• True

• False

• True

• False

in the manual mode, the process will be controlled better than in the Auto mode

• False

• True

• True

• True

in the cascade mode, you can put 2 set points (in each controller)

• True

• maybe

• it is possible

• False

if we opened the bypass of the control valve while the valve was in Auto Mode, what would happen?

• nothing

• the control loop will be useless

• it is like we put the control valve in Manual Mode

• the controller will go coco 🤪

the more complex the control loop the more performance of your process will get.

• True

• maybe

• probably

• false

the most important thing in this life is
