Let's say that we have a half full tank for LPG. Given that the needed liters to fill it up, are liquid, thus incompressible, does the quantity depends on the pressure of the station's tank, or not?
In other words, is it possible to see more litters fill the tank, from a gas station with 12 bar, than from a station with 4 bar?

Wouldn't the difference simply be one of flow rate?;It would take longer to fill your tank at the 4 Bar station than the 12 Bar....
As for the amount of "fuel" you receive, and it sounds as if you think you're getting short measure, surely your own gauge should be a rough indicator? A litre is a litre by any other name, but if the delivery system has an incorrectly set gauge then something isn't going to smell so sweet - Do you have any legal bodies over there (ours is called Trading Standards, a generally useless bunch of form filers, but they do respond to suggestions of short delivery when prompted) which could go and check the equipment at the station?
Or maybe your float needs adjusting?

The pressure in the car's fuel tank is simply a function of temperature (table attached) & isn't affected by the amount of liquid propane present (provided there actually is some). The delivery pump obviously needs to be able to supply at a higher pressure (or it wouldn't be possible to transfer the fuel), but the volume of liquid dispensed isn't affected by the delivery pressure.

The density will be slightly affected by temperature, so you will actually get a tiny bit more fuel by weight (it's measured by volume) for your money on cold days than on hot ones - but the difference isn't enough to worry about.

Thank you all for the feedback. I just had a conversation with a colleague, who claimed the opposite. That if the station's pressure is bigger, then it shall fill more liters in the half filled tank. I was certain, but just to be sure I made the question.
