Question Fueling Meter?

Is there any digital measuring equipment which one can put in the car to measure the exact amount of fuel delivered at the pump? Also, at what temperature is the fuel stored/delivered?

never heard of this. however you can ask any petrol pump manager to measure the quantity of 1 to 5 litre of petrol in a industry approved measurement containers.

All petrol pumps also need to keep a density checking equipment as recommended by most Oil companies and government.

OK, since it's not possible to fit any such device, are there any cars sold in India that measure the fuel in their tanks instead of just showing a full-half-empty gauge?

not sure about that. some do show how many more kilometers you can cover with the fuel available in the tank(known as range).
punto is one

It'd be nice if such a digital gauge was made for Indian cars to help combat fuel pump cheating. If not one showing the true amount, then one that is fairly accurate and updates fast.

I think you can but some "flowmeters" that are available in market. I had asked the same question to my bro and he only pointed me to these flow meters and as per him, making one such meter is very simple it seems

Not quite -- its a hidden feature


The thing is that most modern cars (esp. if they have a DTE display) know roughly how much fuel is in the tank.
However, they probably dont show this as it isn't as accurate as the petrol pump's guages - and they probably don't want a situation where you fill 40 liters at the pump and the car's guage only shows a change of 38 Lts.

Some of the latest dispensers show the density. Whether it is just a figure entered, or measured online, I don't know.

Flowmeters are available. Kent was a common brand. The nutating disc ones wern't very expensive (for people who bought fuel by the tankerload!).

Why the fixation with digital?

I think he's used that term losely to mean "with actual numbers" rather than a needle on a vague dial.


Regarding your topic of fuel density, and how its measured, see these two threads :

Pumps with fuel density display

What should the fuel density be for different fuels? (Fuel Density - what should it be for different fuels)

FYI - fuel volume is only corrected for density (due to varying temperature) when the bunk buys fuel by the tanker, and NOT when the customer fills up their car.

Thanks Rehaan. I meant meters showing actual numerical readings.

I hope such devices come standard on newer cars so we can atleast defeat the short-fueling tricks at the pumps.
