On that matter, since the specific gravity at the pumps has a
permitted +/-4% tolerance, paying by volume purchased is
fundamentally
the wrong measure, in any case.

In your opinion, you mean.

No.

What, it's NOT your opinion?

Stating a fact.

It is *not* a "fact" that selling fuel by volume via machinery with
machine-type tolerances is "wrong".

Please try to comprehend: it has nothing to do with the machine.


Please try to comprehend: "wrong" is a value judgment, not a scientific
measurement.


I make no mistake.

That is just your opinion.

The tolerance level of the pump works out the same no matter what
metric you use.

The tolerance of the equipment in the pump is a different thing to the
tolerance on the specific gravity of the fuel. Measuring by weight
takes away the variability of the fuel.

How would *you* meter typical purchases (five/six gallons) out of
millions of tons of a liquid with slightly-varying specific gravity? It would
presumably have to be independent of any possible tolerance variance in
the measuring equipment at POS.


Simple. I turn up at the forecourt and fill my tank as usual. The bill
would show kilograms instead of litres.


The delivery pump and metering system would be just as liable to tolerance
variance as to weight as it (apparently) is when metering by volume.


How many more times? THE ISSUE IS NOT ABOUT THE PUMP!


How many more times? Whether you meter by volume or weight, you will
still get variance. And that IS to do with the pump.

By the way, good luck with designing a pump which knows how much fuel to
weigh out (for pricing purposes) before you put it into your tank. There
is much discussion elsewhere of Artificial Intelligence but apparently
it has already progressed as far as Artificial Clairvoyance.

How WILL the machine know how much to weigh out in advance of any of it
going into the tank? Will purchases only be allowed in fixed quantities
ordered at the outset? Will filling the tank no longer be an option?

All necessary information was in my first post. Too bad if a person with a
mundane service job and wannabe barrister can't cope with something you were
taught when you were 13.

It's just a matter of encapsulating that remarkable Nugent telepathic
ability. You should donate your brain to research when you die, otherwise it
will be missing out. (But I'm not telepathic and can't begin to imagine how
on earth you make the leap to suppose the change would require a change of
procedure.)

He survived the sinking of the RMS Titanic, but what finally killed him off?

Lightoller died of chronic heart disease on 8 December 1952, aged 78. A long-time pipe smoker, he was living in London during that city's Great Smog of 1952 when he died. His body was cremated, and his ashes were scattered at Mortlake Crematorium in Richmond, Surrey.
