A system for controlling the dispensing of fuel or the like in a vending apparatus, particularly for private use, comprising one or more dispensing assemblies, one or more mobile processing devices, and a central remote processing device, the mobile devices being configured to transmit data originating from the dispensing assemblies toward the central remote device. Each dispensing assembly comprises an electronic controller and dispensing element which comprise an electric pump, the electronic controller being configured to control electronically the electric pump of the dispensing element on the basis of the occurrence of an operating condition of the electrical and/or hydraulic type of the dispensing element of the dispensing assembly.

A fuel storage and dispensing device that includes one or more storage tanks that are housed in a cabinet. A dispenser is fluidly attached to one or more of the storage tanks through a conduit. The dispenser includes one or more safety features to prevent inadvertent dispensing of fuel and to control the dispensing of the fuel.

A liquid discharge system includes a liquid product pump having a sensor for monitoring vibrations passing through an outer casing of the liquid product pump to detect an occurrence of cavitation within the liquid product pump. A system and method for controlling the operation of a liquid product pump in an engine-driven hydraulic discharge system. The liquid product pump has a vibration sensor operable to detect cavitation within the liquid product pump and for providing an electrical vibration signal to a speed control module. The speed control module is operable to process the vibration signal and to produce an electrical speed control signal that is provided to an electronic actuator. The electronic actuator is operable to actuate a motor control lever of a variable speed hydraulic motor to adjust the operating speed of the liquid product pump.

A security device for a fuel dispenser includes a stepping relay having contacts arranged in series between a source of power and a fuel pump such that when the contacts are open, no fuel can be dispensed. The stepping relay is triggered by one or more door interlock switches that are powered by the fuel pump side of the contacts such that, when an access door is opened, the relay is triggered and the door interlock switches are no longer powered, hence, disabled. Therefore, a reset switch that is constantly powered is interfaced to trigger the stepping relay to close the contacts and allow fuel to be dispensed. Preferably, the reset switch is either remotely located or has a security feature.
