    SCAM petrol pumps

    SCAM petrol pumps 15th Mar 17 at 1:36 AM
    I have tested this a few times and before any petrol leaves the nozzle of the sainsburys petrol pump it clocks up 12p, I tested this as I was holding the pump leaver for a while before fuel came out and one day i kept pulling and releasing the leaver, just before the fuel gets delivered 12p appears on the pump cost.

    Has anyone else noticed this?????

    You won't be able to see the flag even if you knew where to look, after decades of exposure to the elements (for want of a better word) it's bleached white now so would be almost impossible to see against the rock

    What really annoys me is when I dispense exactly the amount I want to pay for eg £20 then by the time I get the hose back it has rolled over to £20.01p. Does this mean I am being scammed

    Petrol pumps are subject to Weights and Measures Act monitored by Trading Standards. IIRC they are legally required to operate within +0.3% to -0.3% on a minimum delivery of 2 litres.

    How many of use weigh the products we buy at a supermarket. Most suppliers will over weight a product rather than risk fines. So your 1kg of flour will often weigh 1015g.

    There will always be human error, faulty equipment and in-date calibrations that go wrong. But equally customers can benefit:

    Which is why I'm resisting getting smart Electricity & gas meters.
    My old mechanical meters will have been manufactured to under read in my favour by a few %.
    The new smart meters will be more accurate, so I can only lose out.
    1 or 2% of a £1200 energy bill is worth saving.

    That is a software error, it wont affect the base accuracy of measurement.
    I would have thought in the 21st century they could be made more precise, and set a lot nearer the actual value, but I could be wrong (or is it right?- everything was better in The Olden Days)....

    I think perhaps you're confusing precision with accuracy.

    A £5 digital watch may be more precise than an analogue Rolex, but it's unlikely to be as accurate.

    The meaning of precision changed recently, from what we would now call resolution, to repeatability/reproducibility/lack of random error.

    A precise measurement is repeatable, so you can calibrate a precise instrument to be accurate, then we are talking about "trueness" of the results.


    So in the case of the rolex, it will be precise if every 24hours it reads exactly the same time, but it won't be accurate if I don't set the time to match a standard.

    I haven't used a Sainsbury's Petrol Station for some time now as I no longer live near one however somewhere on their pumps there'll be a Trading Standards sticker from the testing they carry out.
