In GT6, is it possible to get molten stuff from a pipe/tank into a crucible in exact amounts?

And on that similar vein, what would stop me from smelting say all my iron and storing it in tanks and then using molds to have a dispenser of whatever type i want? Which of course would be unrealistic at best.

That is what the Smelter is for, not the Crucible.

You can manually dump Fluids from a Drum to a Crucible using the Measuring Pot, and the Measuring Pot can be set to have a very specific Capacity, see Tooltip on how to set that.
