One fellow claims that by putting an aluminum plate between a non-contact sensor and a too-thick plastic tank wall he was able to increase sensitivity sufficiently for it to work.

This is possibly a dumb question, but might there be a way to use some of these non-contact sensors in combination with resistors between them to vary resistance based on how many were lit up, maybe a variation on a divider circuit, so that they could be used with an ADC chip already implemented on Openplotter, or even a real analog gauge?
