Fuel Sensor

Hello Ardunites,

I am a newbie using Arduino...

Is there any sensor that can determine the level of FUEL/PETROL in a filling station tank.

Regards.

Is the tank above or below ground? If above ground you could measure the head pressure at the bottom of the tank and calculate level, below ground is another thing, especially with gasoline (petrol).

Yes. But no specific suggestions for lack of detailed information. Tank size; available access to tank; material of tank; required accuracy for starters.

It is below ground

Which sensor will I use to take in inputs?

Remember petrol vapors and electric sparks can ruin your day! Without knowing specifics, I would be reluctant to advise.

Yea

Thanks for the tip

Pressure sensor submerged at the bottom of the fuel tank should work. As long as the sensor is gasoline resistant.

Or the good old pressure tube, where the pressure sensor can be kept outside the tank, only the tube goes in. No electrics in the tank this way.

If not too big a tank (max. range 3-5 meters) an ultrasound sensor at the top to measure distance to fuel level - make sure you have one that’s rated spark-free and have the connections soldered and insulated properly.

In any case, especially as this is a filling station which sounds like a commercial operation to me, let a certified expert go over and approve your handiwork. Flammable fuels are not something to mess with.

Your insurers and the local fire department, not to mention your neighbours ;) will probably want certification that everything's intrinsically safe or at least flashproof.

Yea sure.

We all understand the risk and taking necessary measurements.

Thanks for the Replies

in the United States, the level is ALWAYS measured by the delivery truck driver using a calibrated wooden stick. No static electricity and no sparks and the tanks are ALWAYS under ground and double walled with containment devices for leaks.

Hello @Gaspar have you found sensor to meter petrol level sensor, what are you have used, i have same interrested for you.

Thank you Stelio langa
