Hi Graham,
Yes, this magnet/reed switch idea does seem very reliable. Too bad its not
avail anymore. Hmmm.... I suppose someone can make a homegrown cork with a
magnet inside of it for the site glass/pipe, with some reed switches in the
back of it, out of the way behind the sight card.
I think the way the cap. meter reads the water at the bottom of the tank is
a great point, and a very good reason to have at least one in the system!
Was thinking of going with the Tony K idea at one point, but do not know
where to go to get the schematic/build description/programming data. Yes it
is quite elegant soln. Let me know if you have this info.
Regards,
Greg

The neatest float gauge is the one Europa used to sell, It has a magnet
attached to a cork and reed switches at 8 or 10 points to read level.
Very reliable.
Best advantage of capacitance is if there's any water about in the tank
they read full scale. As you say reading varies with fuel type.
Most elegant fuel gauge is Tony K's but you have to build it yourself.
