I am building and ATO-AWC (auto top off and water change) device. I have liquid level sensors from Gavazzi, model VP02EP. My problem is I have no idea how to connect them to an Arduino. Here is a link to the datasheet:

The wiring diagrams are at the bottom of page 2 (the diagram for EP02EP/VP04EP is the correct one.

Looks like a simple diagram, but I have no idea how to implement it. Any help would be great!
