I have been asked about probe corrosion in water level detection systems. My name is Bill Ford and I have been producing water level detection systems (WLDS) for over 5 years. My system was designed specifically to work with distilled water. In over 150 installed systems there has been no reports of corrosion of the probes. Since it does not use electrical conductivity for its operation, there is no DC voltage on the probes which would cause corrosion. For more info see my web site www.wldssystem.weebly.com or Email me at bfinduswlds@gmail.com @import url(http://www.mylargescale.com/Provide...s);@import url(/providers/htmleditorproviders/cehtmleditorprovider/dnngeneral.css);

Bill, Is the probe a porcelain or similar insulator with a metal rod/pin/probe which extends to the “LOW” water line? Is there a specific Ohmic value associated with your system i.e., 10, 30 Ohms or similar? Trying to figure out if this is similar to stuff I work with of 1:1 scale boilers. In my experience the probes never show signs of decay or corrosion, that said “scale” (carbonate deposits), poor electrical grounding, loose wire connections at the probe and or where the probes feedback wire terminates exasperates electrical losses, accordingly these are the typical problems realized herein...

I worked the mechanical end of an experimental but working baby diaper wetness sensor that used a change in capacitance to measure wetness...there are many ways to test for water.

Eric, Interesting project..... Been involved with the dirty end of the diaper buisness, five kids and a customer that runs a diaper exchange pick-up/delivery route... I work with capacitve, inductive and conductivity level sensors too. Sounds like ya'll picked the right sensor for loaded diaper aquisition info. Michael
