I was toying with the idea of making a fuel gauge consisting of an
aluminum tube, with a magnetic float in it which would trip some
magnetic micro-switches at various heights along the outside of the tube
wired with some circuitry to provide a stepped resistance or voltage
output. (like the one from http://www.avnet.co.uk/touchdown but
inside-out).
I would plumb the bottom of the tube to the tank outlet, place the tube
behind the headrests in the baggage bay, and vent the top of the tube to
the filler vent.
No additional holes in the tank, short tubing runs, relatively
lightweight and easily serviceable.
Any thoughts?
Alternatively there is also the very neat concept of measuring the
weight of the fuel using a pressure transducer as designed by Tony -
