Bill: Sounds like you have plenty of experience with the doubtless infinite params that can play games with this topic then! I cannot imagine how inaccurate those mass-produced milometer computers are we see on modern vehicles! I noticed on mine it can say 100km remaining when I park up, then...
Hi Bill, Thank you for your input.
The 1000 / 50cm bit was just an approximation at this stage. As I recall, my calculation of the tank I have worked out that 10mm = 5 liters, so my idea was to have a sensor every 5mm to perhaps achieve 2.5 liter "accuracy".
It is automotive, but the reading...
When you say "fairly respectable"...
I could sink 40mA from the microprocessor directly, if that would be enough --- it will try it!
But if I need more, what do you think the upper milli/amps limit would be from a safety standpoint, assuming I stick with 5v supply (which somehow feels more...
Warpspeed: Thanks for your comments.
The speed of the thing may not be too crucial... I suspect it would take some seconds for the fuel to "drip" off the sensor part anyhow as the level goes down, so that will already create a delay of some seconds. Unless these are teflon coated parts (or...
Hmmm, I solved the ntc config so that actually works surprisingly well. Seeing was believing when I connected the battery in the right place :)
But I still have the same thought about using some other sensor, as the ntc's all seem fairly expensive (considering I might want a stack of 1000 to...
Hello all,
I was reading an old thread (thread240-171250), and noticed some comments from Warpspeed and cbarn24050 about fuel sensor design ideas.
The idea of an ntc matrix seemed fun, so I gave it a go!
However, I have not noticed a very large change in resistance for the ntc in or out of...
