Total stations that add a penny...

[uncinquesei]

Friend of mine just posted on Facebook about a total station that adds a penny however careful he is when filling up. This reminded me of a Total station that i used to use (because of work) that also added a penny to the total (pardon the pun). When i asked about it they said it must be me...
I subsequently googled this and came across one of those sites where people review things (like you'd check the reviews before going to buy a paper...) and a total station came up again with the adding a penny thing...
Anyone else noticed this and put it down to being slightly careless with the trigger?

This happened to me at the Total on Tong Road Leeds no less than a week ago so there may well be truth in the matter

Happened to me at a Jet station, and another station I can't remember which company, possibly Tesco. I put it down to old equipment being pushed too hard with a big petrol price. The Jet station has since turned down the speed of delivery and no longer rolls round a penny, but it now takes longer to fill up.
So, it could just be old equipment delivering fuel at a higher price than it was designed to. If you see what I mean.

Tesco's Total where i used to work always did this, but only on about half of the pumps.

Not as bad as one recently where I managed to get 63.75 litres into a 63 litre tank that still had 70 miles showing on the range. Mmmmm!

Local one to me used to do it alot, then a sticker appeared on the machines saying "This machine has been calibrated and tested by local government weights and measures team"

Doesn't add a penny on any more, I suggest a call to weights and measures

I have fit 40 litres into my 33l tank before!

The quoted volume of your tank probably precludes the filler neck, which could potentially hold a couple of litres depending on your car.

possibly a reserve tank too?

Both the above are plausible, but I still had almost 2 gallons left in a 13 gallon tank and managed to fill up with over 13 gallons. Still iffy IMHO.

The pumps run on flow meters which basically spin as liquid passes through them and counts the number of times it spins in order to measure how much fuel you have bought. These are far from reliable though as, if the flow of liquid is too rapid or if the pressure is too great they can spin more than they should. Effectively overtaking the actual amount of fuel passing through.
The reason I'm telling you this (and I apologise if you already knew), is that by simply loosening a small allen screw you can make the "spinner" more loose and "encourage" it to give a falsely high reading.

If you are that concerned then you need to speak to Weights & Measures, they will gladly test pumps & they have very strict tolerances on how accurate the pumps are. W&M also do regular checks at all fuel stations regardless of whether there has been a complaint or not.

There was a thread on this very same subject a few days ago.
