    摘要: A storage tank leak detection and prevention system that detects a breach or leak in the interstitial space of a double-walled fuel storage tank (101) in a service station environment. The interstitial space is placed under a vacuum using a submersible turbine pump (15) that is also used to pump fuel to the fuel dispensers in the service station and therefore a separate vacuum generating source is not required. A sensing (46) unit and/or tank monitor (42) monitors the vacuum level in the interstitial space over time. If a significant vacuum level change occurs in the interstitial space after the interstitial space is placed under a vacuum level, a catastrophic leak detection alarm is generated. If a minor vacuum level change occurs in the interstitial space after the interstitial space is placed under a vacuum, a precision leak detection alarm is generated. Functional tests also ensure that the leak detection system is functioning properly.

    摘要: Systems and methods for regulating the flow rate of fluid at a fluid dispensing nozzle. In one embodiment, a nozzle includes a body, a spout coupled with the body, and at least one fluid flow path disposed within the body. The at least one fluid flow path is configured for fluid communication with a fluid dispensing hose. An ultrasonic transducer is disposed within the body and operatively coupled with the at least one flow path. Control electronics are in electronic communication with the ultrasonic transducer. The control electronics are operative to cause the ultrasonic transducer to transmit ultrasonic waves into the at least one fluid flow path. The ultrasonic waves are modulated with information representative of a desired fluid flow rate.

    摘要: A pump housing that contains a pump that draws fuel from an underground storage tank containing fuel to deliver to fuel dispensers in a service station environment. The pump is coupled to a double-walled fuel pipe that carries the fuel from the pump to the fuel dispensers. The doublewalled fuel piping contains an inner annular space that carries the fuel and an outer annular space that captures any leaked fuel from the inner annular space. The outer annular space is maintained through the fuel piping from the pump to the fuel dispensers so that the outer annular space can be pressurized by a pump to determine if a leak exists in the outer annular space or so that fuel leaked from the inner annular space can be captured by a leak containment chamber in the pump housing.

    摘要: A vacuum-actuated shear valve (116) coupled between piping (106,140) from a storage tank and piping internal to a fuel dispenser (10) that automatically opens and closes in response to a vacuum level. A vacuum actuator (186) is provided to control a fuel flow valve inside the shear valve (116) . When a sufficient vacuum level is generated to the vacuum actuator (186) , the actuator keeps the flow path valve inside the shear valve (116) open. When the vacuum is lost, the vacuum actuator (186) releases the flow path valve inside the shear valve, which closes it. The vacuum actuator (186) is coupled to a secondary containment space of a fuel-handling component that is drawn under a vacuum level by a vacuum-generating source to monitor for leaks. Thus, if a leak occurs in the monitored secondarily contained space, the shear valve (116) is automatically closed to prevent the flow of fuel from continuing to be supplied to the source of the leak.
