A mobile fluid transfer system. The system includes a fluid evacuation system, a fluid refill system, a sensing system and a control system. The fluid evacuation system comprises a first fluid storage container. The fluid refill system comprises a second fluid storage container. The sensing system is coupled to the fluid evacuation system and the fluid refill system. The control system is coupled to the sensing system, the fluid evacuation system and the fluid refill system. The control system is configured to determine an amount of a first fluid in the first fluid storage container based on a first signal from the sensing system, and determine an amount of a second fluid in the second fluid storage container based on a second signal from the sensing system.

A fuel storage and supply arrangement serves as a source of fuel to be dispensed via at least one fuel dispenser in a fuel dispensing environment. The arrangement comprises a storage tank for containing a quantity of the fuel, fuel piping configured to convey fuel from the fuel storage tank to a fuel dispenser, and a fuel conditioning and filtration assembly having an inlet in fluid communication with the fuel piping and an outlet in fluid communication with the fuel storage tank to return the fuel. A fuel conditioning and filtration element is interposed between the inlet and the outlet, the fuel conditioning and filtration element being configured to remove water from the fuel passing through the filter element. A flow valve allows and prevents flow of fuel through the filter element. Processing circuitry is operative to control the flow valve based on predetermined criteria.

A fluidic interconnect includes a first interface including a liquid port, a gas port, and a cradle; a second interface including a liquid port, a gas port, and a swing bar to engage the cradle, a weight of a container attached to one of the first or second interfaces to drive the liquid port of the first interface into connection with the liquid port of the second interface and the gas port of the first interface into connection with the gas port of the second interface.

The present invention provides a pump cartridge, which is directly connected in-line with one or more filter cartridges in a mounting bracket. It may be paired with an accumulator tank for a pump version, and with no accumulator tank for a smart pump version. The inline design reduces the size of the system, the amount of connections, and the amount of hose required to install the system, which in turn reduces the space required for installation, the number of potential leak paths, and the likelihood of failure of the system due to issues with the hose.

A fuel dispensing device can include a housing, a fuel supply pipe for fuel inlet, a fuel dispensing pipe for dispensing fuel, a fuel pump for pumping fuel from the fuel supply pipe to the fuel dispensing pipe, a fuel filter for filtering fuel to be dispensed, a metering unit between the fuel supply pipe and the fuel dispensing pipe and a control for controlling a function of the fuel dispensing device, wherein heating is provided for heating at least the fuel filter. A method for controlling this fuel dispensing device is also disclosed, wherein at least the fuel filter is heated when outside temperature is near or below fuel freezing point

A vacuum assembly includes a housing and a movable assembly positioned within the housing. Movement of the movable assembly relative to the housing creates a low pressure area. A fluid flow conduit is in fluid communication with the low pressure area. A leakage valve is disposed within the fluid flow conduit and is movable between a first position and a second position to restrict a flow through the fluid flow conduit upon detection of an undesired fluid within the low pressure area.

A tanker truck offloading manifold method. The tanker truck offloading method includes detecting a tanker truck in at least one of a plurality of offloading stations, energizing a blower having an inlet duct coupled to a tank receiving fluid from the plurality of offloading stations, the blower to draw gasses from the tank when at least one tanker truck is offloading at least one of the plurality of offloading stations, de-energizing the blower when no tanker truck is offloading at any of the plurality of offloading stations, energizing a pump having an inlet coupled to the tank when the tank level is above a predetermined high level, and de-energizing the pump when the tank level is below a predetermined low level.
