How do I add water and diesel sensor?

[affinite]

Affinate, what sensors are you using? Do you have a spec on them.

Hi
Im using DS18B20 1 wire sensors (as specified for OpenPlotter) for temperature
For fuel I'm using a 190ohm resistive float sender by Wema. This was the original fuel sender. 
For water etc I plan to use further WEMA senders like this one wema sender
