Abstract: A method and system for tank overfill prevention comprising the steps of supplying fluid to the interior of the tank by means of a dispenser, measuring the dispenser pressure P d and flow rate α, determining at equal time increments 8t a number of quantities representing tank pressures from the said dispenser pressure and flow rate measurements, and deriving from the said determined quantities representing tank pressures, another quantity representing the rate of increase of tank pressure with respect to time, comparing the quantity thus obtained with a preset critical value, and shutting off the fluid supply, if this said quantity exceeds the said preset critical value and if the said flow rate α is less than a preset critical value.
