Boy, that was it, and that was fast, Dave!

Thanks so much.

I thought I had pretty much most of Bruce's articles Scrapbooked in my Firefox, but somehow this one I did not.

Now to see if this range can be increased to a couple of feet. Might not be difficult since the whole environment, including the reflector can be in a tube, isolated from the ambient. Yup, thats right, my quest for the 'perfect' liquid level detector continues.

Thanks again.
