Those Radio Shack boards you suggest are great.

I've made 15 DPDT Latching DIP relay modules for my model railroad automatic signal control blocks using them.

When you've eliminated the impossible,
whatever remains, however improbable, must be


weather proof connections are possable , but the 3 sensors part makes it difficult. since your reducing your wire count run.

I agree.

OP, you ever consider a different sensor type?

How about an automotive fuel tank sending unit?

Fairly inexpensive, reliable, built to take the elements, don't need floating balls in your tank and you'd get a more acurate reading due to it being variable not stepped.

Just throwing it out there.

Good luck!


agree  roncoop , even just 3 wires danging in the water at hight, but i think he said something about already having them- (didnt feel like rereading) :)  so i went with that possable solution - Even just a POT connected to a flowing arm would have worked :)

I use these on farms for measuring dam and tank levels:


The good thing is they only need three wires, they provide infinite measurement (not just three levels) and they have no moving parts and are not in contact with the water. i.e. no wear and tear, no corrosion or fouling of terminals.

For $26 they are simple to use and save you time and money over cheaper but less reliable systems.
