Abstract: A fuel storage system has a tank access chamber with improved monitoring, servicing and maintenance capabilities. In particular, the chamber includes a sump monitored by a liquid sensor whose proper function can be automatically checked remotely, e.g., via an electronic controller or remote manual operation. In cases where such a check indicates a need for physical inspection of the sump sensor, the present system provides for sensor removal and installation by service personnel from a location outside the tank access chamber. Thus, the present system facilitates regular inspection and routine or unplanned maintenance without the need for a person to physically enter the tank access chamber.

The fuel delivery system may conserve energy by selectively activating the one or more pump assemblies and the one or more controllers.

Abstract: An overfill valve associated with a drop tube segment fluidly connected to a fluid reservoir and a structure for securing drop tube segments are described. The overfill valve includes a valve body positioned within the drop tube segment and, in certain embodiments, a non-contact valve actuator positioned exterior to the drop tube segment and operable to actuate the valve body from an open position to a closed position without requiring any physical penetration through the wall of the drop tube segment. A variety of internal actuators are used to actuate the valve body within the drop tube segment. The structure for securing drop tube segments provides a first drop tube segment with a groove into which the wall of a second drop tube segment can to deformed to seal and fasten the two drop tube segments to each other.

Abstract: A sump for a fuel dispenser which allows wiring to pass from beneath the ground vertically upwards through the footprint of the fuel dispenser without compromising a wall of the sump and without providing access to the ground positioned beneath the footprint of the fuel dispenser for a fluid contained within the fuel dispenser, including fuel leaks from the piping contained within the dispenser. In an exemplary embodiment, a sump frame is provided which mates with an open upper portion of the sump which provides access to the sump. The portion of the frame extending over the opening to the sump is generally open, allowing passage of fluids from within the fuel dispenser to the sump. The sump frame further includes a conduit entry frame adapter which extends beyond the perimeter of the sump, but which is positioned within the footprint of the fuel dispenser.

Abstract: Systems and methods for detecting a failure in a Stage II fuel vapor recovery system are disclosed. An exemplary failure is a restriction in the vapor recovery system. In one detection system dispensing points may be flagged if it is determined that there has been a series of detected A/L ratios at the respective dispensing point below a first threshold. Further, an estimated ORVR penetration percentage may be determined for each dispensing point. In a second detection system an average A/L ratio for each dispensing point may be determined. The average A/L ratio may be an approximation of the average A/L ratio for non-ORVR transactions.

Abstract: A system and method for detecting phase separation in storage tanks is provided. At least one float has a density calibrated to detect a density differential among surrounding fluids. The float is buoyant on a relatively more dense lower layer of fluid such as phase separated fuel or pure water, while remaining submerged in a relatively less dense upper layer of fluid such as a gasoline/ethanol blend. A detection device sends a signal when the float rises or falls above or below a preset acceptable level.
