The motor and pump that dispense are not precise metering devices, plus you have the velocity that the fluid is traveling at. Hard to stop that on a dime (literally).

Pumps ain't exactly cutting edge technology.
I've known a few guys who will spend 30 minutes fueling up with diesel at truck stops and never pay a dime. They flow so fast, you can get them to trickle fuel without registering on the meter. |

Ending slowly results in a more precisely metered volume - resulting in the gas station dispensing an amount closer to what you paid for than if it shut off while flowing at a higher rate.

To prevent pressure surges when the flow cuts off. A good thought but no. If that were the case every dispense transaction would require an expected shutoff amount - which credit cards (which don't hit the dollar limit) and post-pay cash transactions do not. |

Shutting off a liquid stream abruptly (such as quickly closing a valve) results in a "hammer" effect, which can cause premature wear on pipes, fittings, etc. Remember, all the moving fluid has mass and momentum - which can be very great depending on size and length of pipe. Maths: Lets say you have a pipe of 3" ID 100 feet long filled with water. That's 108 cubic feet of water which weights about 6700 pounds. Now, imagine all that water and force was moving at 3 feet per second - and you shut it off suddenly. Imagine a halt ton pickup truck rolling towards a brick wall at 2 mph. ETA: I see you already knew this but hell i'll leave it. Didn't do maths for nothin.

I want to know why the electronics are so slow on gas pumps.
Swipe card, wait 15 seconds, enter zip, wait 15 seconds, select "no i don't want a car wash", wait 15 seconds, select grade of fuel, wait 15 seconds, pump gas and replace nozzle, wait 15 seconds and finally decide if you want a receipt or not. Its 2016 and the electronics side of the transaction is no faster than it was a decade ago. Doesn't compute. |

Fellas - gas pumps are pretty closely controlled by your state's weights and measures division.
I don't deal with measurement on the fuel side. But I do deal with measurement on the Crude oil side - building equipment that is accurate to 1/10000th of a bbl. Measurement is complex and tightly controlled by numerous governing bodies. Everything from ANSI to API to ITPS, etc. These are groups that sit around and consider stuff like "Should we use the 1968 temperature scale or the 1980 temperature scale" and "What precisely IS 'one gallon.'" or "At what temperature should 'one gallon' be 'one gallon.'" I'm sure some gas stations get away with shenanigans - but in the vast majority of cases you can be relatively certain the gas pump is dispensing "fairly." Next time you're at the pump look around for the little sticker that shows it's been calibrated and certified by whatever body in your state handles it. |

Your second picture includes a diagram of the motor, pump, fire safety / recirc valve, meter, etc. Are you saying "pump" but meaning "meter?" Regardless - if what you are talking about was a universal problem all transactions would require a ramp-down before full stop. Which only pre-pay transactions do. |

Its 2016, use a cc at the pump and this won't happen. Then you don't have to hike through your 14 degree temps into the store to pay w/ loose change. Well, he has a point. You're the one whining about having to wait a few extra seconds. If you paid with a cc and filled up your tank each time, think of all the time you would save and all the whining we would not have to endure. win/win Credit cards are for poor people. Derp |

Quote HistoryQuoted: They'd put VERY light pressure on the handle and it'd start dribbling fuel, but the pump wouldn't read it. It only worked on the big rig style pumps (huge hose, nozzle, etc.). Like I said, it might take them 30 minutes, but it worked. Honestly, I don't even think the pumps had a digital read, I think they were analog meters. Quote HistoryQuoted: Quoted: Quoted: Pumps ain't exactly cutting edge technology. I've known a few guys who will spend 30 minutes fueling up with diesel at truck stops and never pay a dime. They flow so fast, you can get them to trickle fuel without registering on the meter. How the hell does that work?

Around here the self car wash stalls have to set the hose wand to dribble a bit of spray to keep the hose from freezing. If you are patient, you can wash (more of a rinse really) your car without paying the two bucks in quarters to get full power. I use it to get the initial washing done so can start with the soap brush wand. |

The reason why the fuel starts to slow down on a preset payment is because of the
two stage valve is shutting the main stage and letting the secondary stage complete the sale. |

I believe they hold the nozzle valve open when they do it. Quote HistoryQuoted:

I've seen cutoff jean short types pick up the hose to empty that last bit of gas into their tank after the pump stops. Which is stupid because the valve is on the nozzle. All they're getting is whatever is left in the nozzle spout - if that. I believe they hold the nozzle valve open when they do it. Modern pumps won't drain the hoses like that anymore. |
