Device for dispensing liquid fluids
First Claim
1. A dispensing device for dispensing liquid fuel from at least one storage tank through at least one fuel nozzle, wherein the liquid fuel is conveyed by a fuel pump from the at least one storage tank to the fuel nozzle, wherein the amount of liquid fuel dispensed is measured by a measuring device including an impulse sender, wherein vapors are removed from a fuel tank to be filled by a vapor pump via a vapor removal opening provided at the fuel nozzle, and are returned into the storage tank via a vapor return line, wherein the improvement comprises:
- the measuring device including a computer producing data sets comprised of address bits, data bits, and check bits for a display electrically interconnected with the fuel pump, for a control unit of the vapor pump in order to control pumping output depending on the amount of liquid fuel being dispensed, and for a central computing unit of a gas station;
a network for transmitting the data sets to the display, the control unit of the vapor pump, and the central computing unit of the gas station.

Abstract
In a dispensing device for dispensing liquid fuel from at least one underground storage tank through at least one fuel nozzle, wherein the liquid fuel is conveyed by a fuel pump from the underground storage tank to the fuel nozzle, wherein the amount of liquid fuel dispensed is measured by a measuring device including an impulse sender, wherein vapors are removed from the fuel tank to be filled by a vapor pump via a vapor removal opening provided at the fuel nozzle and returned into the underground storage tank via a vapor return line, the measuring device includes a computer producing data sets comprised of address bits, data bits, and check bits for a display correlated with the fuel pump, for a control unit of the vapor pump in order to control pumping output depending on the dispensed amount of liquid fuel, and for a central computing unit of a gas station. A network is provided for transmitting the data sets to the display, the control unit of the vapor pump, and the central computing unit of the gas station.
