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? |

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.) |

AIUI it isn't the sulphur and nitrogen that cause the problem but particulates. 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. https://en.wikipedia.org/wiki/Charles_Lightoller |
