A fluid dispenser, includes: a fluid dispensation pipe, for receiving a fluid and controlling a dispensation the fluid; a MEMS sensor, for sensing a movement of the fluid dispenser, wherein when the movement is determined to be in an abnormal status, the MEMS sensor generates an alarm signal; and a dispensation stopper, for stopping the dispensation of the fluid according to the alarm signal.

An apparatus, including a monitor system which includes a microphone, a first power supply, and a transmitter which transmits a first audible sound, indicative of a normal flow of fluid into a tank, or transmits a second audible sound, indicative of a need to cease a flow of the fluid into the tank; an attachment device to which the monitor system or the microphone is attached and which is attached to a ventilation pipe or an object in a vicinity of the ventilation pipe; and a receiver system which includes a receiver, which receives the first audible sound or the second audible sound, a second power supply, and a speaker which provides a first audio output, indicative of the first audible sound, or a second audio output indicative of the second audible sound. The speaker outputs the first audio output or outputs the second audio output.

An apparatus, including a monitor system including a microphone, first power supply; and transmitter which transmits a first sound indicative of a normal flow of a fluid into a tank and a second sound indicative of a need to cease the flow of the fluid; an attachment device, wherein the monitor system or microphone is attached to the attachment device, and the attachment device is attached to, or attached to an object in a vicinity of, a ventilation pipe; and a receiver system which is headset, earpiece, wearable device, or handheld device, which includes a housing; receiver which receives the first sound or second sound; second power supply; and speaker. The speaker outputs the first audio output indicative of the normal flow of the fluid into the tank and outputs the second audible sound indicative of the need to cease the flow of the fluid.

A breakaway coupling with system-tight end flanges on the first and second coupling halves is provided. The end flanges have oblique or conical surfaces and are embraced there by ring segments, which in turn are pressed against the oblique or conical surfaces by a pre-stressing element. With an excessive pull or tension on the coupling halves, the latter can separate counter to the force of the pre-stressing element.

A refueling adapter configured for permitting a vehicle having a twist-lock coupling-style fuel receiver to be fueled from a fuel source having a dry-break coupling-style fuel dispenser. The refueling adapter having a body portion and a mating assembly. The body portion has a first end and second end. The first end of the body portion is configured for dry-break coupling with a fuel dispenser. The second end of the body portion is configured for rotatable engagement with the mating assembly. The mating assembly is configured for engagement with a twist-lock coupling-style fuel receiver.

An apparatus is for a hazardous-fluid delivery vehicle configured to convey a hazardous fluid, and for a storage tank configured to receive the hazardous fluid. The apparatus includes a fluid-input section configured to fluidly connect with the hazardous-fluid delivery vehicle. A valve assembly is in fluid communication with the fluid-input section. A fluid-output section is configured to fluidly connect the valve assembly with the storage tank. A valve actuator is operatively coupled to the valve assembly. The valve actuator is configured to actuate the valve assembly between a valve-closed state and a valve-opened state for the case where the valve actuator receives an actuation signal from an operator that is situated at a predetermined safe distance from the valve assembly. The predetermined safe distance is located proximate to the control section of the hazardous-fluid delivery vehicle.

A coupling comprising a first body member and a second body member. The first and second body members are operative to releasably connect together. The first and second body members define a fluid flow path therein when the first and second body members are connected together. The first and second body members are operative to disconnect from one another in response to a predetermined tensile force. At least one valve member is disposed within at least one of the first and second body members and is movable from an open position to a closed position with respect to the fluid flow path upon disconnection of the first body member from the second body member. A sensor is disposed within one of the first and second body members and is operative to sense whether the first and second body members are connected together.

A system detects a fuel dispensing operation that indicates fuel is being dispensed from the fuel dispensing terminal. The system determines an identifier value associated with a volume of fuel dispensed from the fuel dispensing terminal. The system determines a measured volume per unit time parameter associated with the fuel dispensed from the fuel dispensing terminal by dividing the determined identifier value by a unit parameter. The system compares the measured volume per unit time parameter with a threshold volume per unit time parameter. In response to determining that the measured volume per unit time parameter is less than the threshold volume per unit time parameter, the system communicates an electronic signal to the fuel dispensing terminal that instructs the fuel dispensing terminal to stop dispensing fuel.

Filling nozzle for delivering a fluid, comprising an inlet (13) for connection of a fluid feed line, an outlet (14), a main conduit (15) connecting the inlet to the outlet, a main valve device (16) for controlling a flow of fluid through the main conduit (15), a control lever (17) for actuating the main valve device (16), an automatic safety shut-off designed to move the main valve device (16) to a closed position independently of a position of the control lever (17) when a fluid pressure at the inlet (13) falls below a minimum value, and comprising a preloading device (18) which preloads the main valve device (16) into the closed position and effects a variable opening cross-section of the main valve device (16) depending on a fluid pressure at the inlet. According to the invention, the preloading device (18) is designed to produce a discontinuous opening characteristic of the main valve device (16) in such a way that a closing force acting on a valve body (20, 20, 20, 22) of the main valve device is reduced in a first opening cross-section range extending from the closed position of the main valve device (16) to a limit opening cross-section.

An apparatus configured to detect a gas hose pull away event at a gas station includes a gas hose sensor configured to detect when a gas hose is pulled away from a gas pump, a visual alarm configured to be activated in response to detection that the gas hose has been pulled away from the gas pump, an audible alarm configured to be activated in response to detection that the gas hose has been pulled away from the gas pump, a mounting bracket configured to attach the apparatus to a fixed location on or proximate to the gas pump, and an electrical connection configured to provide electrical power. In one example, the gas hose sensor includes a cord, a wire, or a string that is attached to the gas hose. In another example, the sensor is attached to the gas hose utilizing a clamp, a tie, or a magnet.
