pls help me to build water level meter.the one i made uses 5 probes for empty,quarter,half and full.Now a want a better design.can i use uvison and simulate something. what
I recently designed a simple and fully functional water level detector for air conditioner water drip trays in computer rooms. It uses stainless steel contacts, a simple mosfet detector driving another mosfet and relay combo. I feed 12V to one of the contacts, via a 10K resistor, the other contact, when water is present, turns on the mosfet, fires the relay, giving an alarm. I see no reason why the same circuit couldn't be applied to multiple level/trigger points.

He probably already has a similar solution. Since he did not specify what he meant with "better", I made the assumption that he is interested in a continuous measurements, instead of having fixed detect levels.
.. go to a junk yard and get a gas level sensor from some car. This is the very thing Per suggest.
