Thread: [PIC]: How to measure level of liquids and sense
face BY : Craig Lee email (remove spam text)

I use a conductivity system with two probes referenced to a common probe
for sensing and controlling liquid levels.  The system is designed using
AC voltage to limit mineral plating to the electrodes.  I wouldn't want
to use it in a flamable liquid! It acts as kind of a Schmitt Trigger.
An output relay is turned on once the top electrode is emersed, and the
output is turned off once the lower electrode is out of the liquid.

Is this of interest to anyone?
