You and FW28z have put a lot of thought, time, money, and engineering into this and, while I haven't read the complete thread, I really respect what yall have done here.
Some people would say "Well I don't need that accuracy since I just use it for weekends and relatively short stays", but those like me, that stay in the RV for weeks or months at a time in places without sewer hook ups could really benefit from an accurate, relatively fool-proof, reliable level indication.
Again, I really respect the work yall have done on this and it looks like it could be easily transferable to practically any tank, given access to the tank.

Thanks.
I don't expect much to be stuck to the inside wall where the sensor is mounted since its outside the tank with no protrusions in the tank (like the conventional sensors). Even a little driving should slosh stuff around enough to get an accurate reading. However, so far all my testing has been using plain water; not sure if the different chemical composition in the tanks will change the readings at all (heck from fill to fill the composition will change).
We can't take all the credit: commercial systems for tank level monitoring using this technique have been available for a while--they just are too expensive for RV use. We were just trying to DIY it at a more affordable level (and now that
a DIY sensor board is available that made all the difference).
I would think that anyone with an RV would be interested in more accurate level readings from all 3 tanks.
