摘要： A system for blending low and high octane gasoline includes independent flow paths for each fuel between a supply source and a composite blend manifold and nozzle assembly, with the rate of flow of fuel in each flow path being under individual closed loop control, under an algorithm for comparing the ratio of the actual accumulated volumes of the low octane to the high octane fuel, relative to a statistically determined ratio of the ideal volume of said low to high octane fuel for the total actual accumulated volume of the sum of the volumes of the fuels at a given time, for providing a perfect blend relative to a preselected blend ratio.

摘要： A leak collection chamber is provided inside the housing of a fuel dispenser. The leak collection chamber collects any leaked fuel from fuel handling components inside the fuel dispenser so that the fuel does not leak to the environment. The leak collection chamber can be removed from the fuel dispenser for evacuation. The control system inside the fuel dispenser can determine the liquid level inside the leak containment chamber and generate signals and alarms if the liquid level exceeds a threshold liquid level value and/or the rate of increase in liquid level exceeds a threshold liquid level increase value. The control system can alert service personnel and/or other systems of the leak collection chamber liquid level. Further, the control system and/or other systems shut down the submersible turbine pump that services the fuel dispenser with fuel in response to catastrophic leak condition.

摘要： A shear valve assembly for a fuel dispenser that ensures that the energy from an impact to the fuel dispenser causes a shear valve placed inline to the fuel supply conduit to engage if there is a possibility that such impact could cause the fuel supply conduit to break thereby causing a leak of fuel to the environment. The shear valve assembly may be constructed as part of the fuel dispenser during the manufacture of the fuel dispenser, or the shear valve assembly may be constructed separately from the fuel dispenser and attached to the fuel dispenser in the field during installation of a fuel dispenser.

摘要： A system for blending two-blend components to form a blended final product including a first supply line for supplying a first blend component at a first flow rate and a second supply line for supplying a second blend component at a second flow rate. The first supply line and the second supply line intersect to form a blended product line. The system further includes a blended product measuring device positioned in the blended product line for measuring the flow rate of the blended product and an auxiliary measuring device positioned in the first supply line for measuring the flow rate of the first blend component. The auxiliary measuring device may have a degree of accuracy less than that of the blended product meter. Alternatively, the auxiliary measuring device may have the same level of accuracy as that of the blended product meter. A calculation device determines the flow rate of the second blend component by measuring the difference between the flow rates measured by the blended product meter and the auxiliary measuring device. A method for determining the inputs to a blending system for blending a first blend component and a second blend component to form a blended mixture. The method includes measuring the flow rate of the blended mixture directly using a blended mixture flow meter and measuring the flow rate of the first blend component directly using an auxiliary measuring device having substantially less accuracy than that of the blended product flow meter. The flow rate of the second blend component is determined by measuring the difference between the blended mixture flow rate and the first blend component flow rate.

摘要： The present invention provides a system and method allowing customers to conduct a transaction at a fuel dispenser and obtain cash back in association with the transaction at the dispenser or a common terminal in the dispenser forecourt. The system may include a cash dispenser at the fuel dispenser, fueling position, or the central terminal, or, alternatively, a delivery system configured to deliver cash from a central location to the customer at the dispenser, fueling position, or central terminal. During a transaction for purchasing fuel or other products associated with the service station, a customer is provided an opportunity to select an amount of cash to be dispensed or delivered in association with that transaction. Providing a customer the opportunity to receive cash back in association with a dispenser transaction will attract more customers to the station because of convenience as well as provide customers with more disposable cash to spend at the associated quick-serve restaurants and convenience store.

摘要： An in-dispenser leak pan provided inside the housing of a fuel dispenser. The leak collection chamber collects any fuel that leaks from fuel-handling components located inside the fuel dispenser above the pan. The pan is secondarily contained by an outer pan or container such that an interstitial space is formed therebetween. If a breach exists in the top part of the pan, the captured leaked fuel will be contained in by the outer pan in the interstitial space. The interstitial space of the pan is drawn under a vacuum level using a vacuum-generating source to monitor for leaks. If a leak is detected, a control system may generate an alarm and/or cause the submersible turbine pump to stop supplying fuel, or cause the dispenser product line shear valves to close, thereby only stopping fuel flow to the individual fuel dispenser containing the leak.
