gas gauge

[fnkngrv]

I have heard of people actually using something like this to check their fuel levels even in their cars. I saw it on some forum from the UK where they modded the thing to work with a much smaller tank:

The fatal flaw that I see with this is that if it is sonic and the fuel is moving of course the sonic reading wouldn't be that accurate anyway right? I mean you would essentially have to park the car to get a solid reading right?

The yaris tank doesn't have any baffles (other than some 3/4" high ridges in the bottom of the tank) , so the fuel sloshes like you wouldn't believe. I can watch the raw values from the sender with my YarGauge, and it's a wonder that the gas gauge is able to be in the least bit accurate. The only time I can get an accurate level is when the car has been sitting still for about 10 seconds or so. In motion, particularly with a half full tank, the values will just oscillate from one end of the range to the other.
