Help How detect amount of fluid in a container

[Immersive_Matt]

Hello,

I am trying to create a cooking game where you can blender fruits and pour the juice into a container. For the game, I need to detect if a container was fill and how much liquid was in it.  I also need to be able to distinguish between different types of liquid like apple juice or orange juice to make sure the correct liquid is in it. What would be a good way to do this? 

Thank you
