A fuel dispenser system is provided including a partition part to separate a fuel dispensing unit from at least one electrically powered component. The partition part can be configured and arranged to seal the at least one electrically powered component from exposure to gas vapors emitted from the fuel dispensing unit. The fuel dispenser unit can include a fuel dispensing nozzle and a hydraulic component. The system can include additional fuel dispensing units. The fuel dispensing nozzle can be configured to dispense CNG, and the additional fuel dispensing nozzle can be configured to dispense CNG or another type of fuel. The at least one electrically powered component may include a transaction terminal.

System and method for measuring the level of gas in liquid form in a composite pressure vessel that uses electrical capacitance to perform the measuring wherein the system comprises: a sensor unit suspended from an inlet-outlet unit and arranged to extend into the pressure vessel, wherein the sensor unit comprises a capacitive measuring unit for measuring the level of gas in liquid form in the pressure vessel, at least two sensor electrodes connected to the capacitive measuring unit, a communication unit for communicating the information measured by the capacitive measuring unit, and a power unit for supplying power to at least one of the at least two electrodes, the capacitive measuring unit and the communication unit.

A diversion fitting for a continuous flow liquid supply system. The diversion fitting includes a flow-through conduit including a first arm and a second arm. The flow-through conduit forms a flow-through channel between the first arm and the second arm along a centerline. The diversion fitting includes a leg extending perpendicular to the centerline and forms an inlet flow channel. The diversion fitting includes a diversion ramp disposed in the flow-through conduit aligned with the inlet flow channel. The diversion ramp is disposed at an angle with respect to the centerline such that the ramp faces toward the first arm and the leg. The diversion ramp is disposed within the flow-through channel between such that a first portion of a fluid flow entering the first arm is diverted into the inlet flow channel and a second portion of the fluid flow continues to the second arm.

In a nozzle for a pressure vessel, and a pressure vessel including the same, the nozzle connected to a liner forming a pressure vessel includes a connecting portion, a lower side of which is connected to the liner, and including an internal passage fluidically-communicating with an interior of the liner, and a tubular first nozzle portion mounted on an upper side of the connecting portion, and being detachable from the connecting portion.

A pressure vessel that is able to store fluid includes a plurality of main body portions provided with a space inside, and a connecting portion to which one ends of each of the main body portions are connected respectively, and communicating with the main body portions to one another. A cross section perpendicular to a longitudinal direction of the main body portion has a substantially quadrilateral shape. The main body portion includes a reinforcing member that connects a pair of opposing surfaces within the space.
