Capacitance will change as a function of water purity.

I'm not sure which way to go at the moment I think I may try measuring the pressure in the Air tank since I have most of the parts for this handy. I guess I would also like to try some of the other options (I really like the Perspex rod stuff). Also did anyone see the article I saw with the capacitance method in it. I think it may have been on Circuit Cellar (or possible Elektor), anyone any experience of using this? Andy -- http://www.piclist.com#nomail Going offline?
