How would I use Combinators to control oil?

[Peter34]

Based on what's in last Friday's "Facts" blog post, can somebody explain how exactly I'm supposed to use Combinators to control the flow of oils, e.g. how much to crack vs how much to use to make Solid Fuel, and having some kind of "low Crude Stores" signal to alert me and the other players to the need to go out and set up more Pump Jacks to increase incoming?

Because I'm not quite getting it...

I know there'll be Youtube tutorials made, some weeks after alpha 12 is released, but I'd like to get a head start on things.

One of the devices you will be able to control will be "power switches".

Then it's simply comparing the liquid levels and then turning on/off the power to the cracking plants

Sure, but I mean more specifically...

Measure the contents of a liquid tank; turn on/off some pumps depending on content... I'm not sure about it, but that is already part of some mods.
