I've mentioned this before and I'm still kicking it around, just so many things going on I'd like some opinions before I start investing in a few parts to attempt it as well as if it's actually feasible enough to even bother with exploring.
I'm trying to figure out a way to determine how full (or empty) a tank is by hitting it with a sonic pulse and looking at the resultant reflection that returns.
The real world: Most motorcycle tanks don't have any sort of gas gauge on them and due to their design of straddling the frame it isn't really feasible to introduce any sort of sensor down the filler neck from the top. On top of that they're of an irregular shape.
Let's say I've got a metal tank that holds four gallons and it's half full.
Obviously I've got 2 gallons of liquid in it and two gallons of free air space.
If I attach some sort of piezoelectric device to the outer metal of the tank, hit it with some sort of pulse then look at the (hopeful) reflection is there going to be enough of some sort of variation returned that would indicate what percentage/how much of the full volume is occupied by liquid and how much is occupied by free air space?
