SEMA 2009 - Fuel Level Sensor

Rob Wray from mp3Car takes a look at a self calibrating fuel level sensor. It uses a new technology called variable capacitance to measure the fuel level. Because this reads via voltage, it should be able to integrate with a fusion brain.

If you have an odd shaped tank like Malcolm i would think you could probably calibrate the sensor to match the size and shape and give you an accurate gallons rating.
I agree this would need some mild modifications to be readable on a PC but I wouldn't think it would be more than a day of work for an experienced EE (electrical engineer) or software guru.Different fuels....... its really nothing groundbreaking just something no one has come up with yet - variable capacitance is at least 10 years old commonly used with temperature sensing or other similar environmental sensors. I was pretty sure it was already used in a few modern cars but I could be off about that.
Its not as simple as connecting directly to your fusion brain unless it has built in conversion circuitry. Most likely you will need to setup a resistor bridge to measure capacitance.What is the advantage over a stock fuel level sensor?
