I think I got it. I confirmed the following resistance values for T4 Westfalia 1991:
Full -> 0 Ohm 2/3 -> 0,72k 1/3 -> 1,62k Empty -> 6,2k So, instead of using a float and reed switches, I am thinking of a simple 4+1 parallel wire system, or tracks on a PCB, using the conductivity of water. As the water level rises (green line), the resistors connect in parallel. No moving parts, wires are immersed in water. It should work. Anybody sees a mistake here? |
