LCD bar graph

[Dennis Lowe <DennisL@inovatec.co.uk>]

I,ve never seen an off the shelf LCD bar display module, but if you are
going to use an LCD maybe you could use a digital voltmeter module (these
are relatively cheap) together with some circuitry for scale conversion.

What are the current thoughts on the construction of a sensor? I,ve seen
references to differential pressure sensors. Would this measure the
pressure at the bottom of the fuel tank against atmospheric?
