[Mondeo] Gazol measure

Hi there,
I don't know if this is a problem or not, here is my question : On my Mondeo, the gazol measure (into the "cockpit") shows the gazol level
even if the engine is stopped and keys out...
I have unplugged the battery, and the measure still doesn't go to "0" Is it normal ?
Thanks for your replies.
