T&T: Subject: Re: Waste tank level sensor

[Greg Bowers]

I bought just such a thing at Wolf's Marine in Benton Harbor MI a few years
ago.  I used a hole saw to cut a 4" hole in the top of my tank and mounted
it there.  It has three stems of different lengths with floating magnets
that ride up the stems.  That is wired to indicator panel on the helm and
while I didn't wire the cutoff in, the last (shortest) stem is designed to
break the circuit to electric heads so that you can't flush them.  The other
two stems are wired to yellow and red indicator lights.  It works great but
the info is on the boat and alas I am not.  It will be about two weeks but I
can get it for you then if you still need it.
