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.

A removal system (1) for a container designed to receive a fluid, with an extraction head (4) and a dip tube (5) that can be fastened thereto. By means of the extraction head (4), fluid can be removed through the dip tube (5) from the container (3) or fluid can be fed into the container (3). The extraction head (4) can be fastened to the dip tube (5) by a displacement movement. Alternatively or additionally, a target position of the dip tube (5) at the extraction head (4) is monitored by means of an optical sensor (12).

A flow control valve is provided including a valve aperture in a valve body configured to convey fuel from an inlet to an outlet, a valve element configured to close the valve aperture to block flow of the fuel, a valve actuator configured to shift the position of the valve element between a closed position and an open position, and an antifraud circuit. The antifraud circuit is configured to receive a signal to open the flow control valve, determine if the signal is legitimate based on a signal characteristic, cause the flow control valve to shift to the open position in response to determining that the signal is legitimate.

A product delivery vehicle system includes a product delivery vehicle with at least one tank compartment. The system includes an internal valve fluidly coupled to the tank compartment, a control valve, and an air system comprising a main air valve and a solenoid valve fluidly coupled to the main air valve and to the internal valve. The solenoid valve is operable to open and close the internal valve. The system includes an electronic control unit communicatively coupled to the control valve, the main air valve, and the solenoid valve. The system includes a tank tag reader operable to read a tank tag and transmit a tank tag indicator associated with the tank tag, the tank tag indicator indicative of a stored liquid type in a distribution tank. The electronic control unit may maintain the internal valve closed and the control valve locked when a product type mismatch is detected.

The invention relates to a quick-change device for a filling adapter for filling vehicles on assembly lines in the automotive industry, on which circuits and containers of the vehicles are filled with operating materials which, starting from a filling system, are fed into the respective circuits and containers via hose assemblies with pneumatic and hydraulic lines and a filling adapter, wherein a separate connection plate is arranged at the separation point of the hose assembly from the filling system, and wherein a connection block is designed as a functional counterpart to the connection plate on the filling system. It is the object of the invention to create such a quick-change device which enables automatic clamping of the connection plate and connection block and which is structurally integrated into one of these two assemblies. The object is achieved in that the connection block (1) comprises a continuous channel structure (6) along its central longitudinal axis, in which structure a tie rod (3) is arranged, and in that an assembly (5) with a pneumatic cylinder (7) is arranged on the connection block (1) on the end face opposite the connection plate (2), wherein the tie rod (3) is enclosed in the channel structure (6) on a section of its axial extension by a spring assembly (4) which is supported in a fixed position on the tie rod (3) at its two end face sections by means of a respective fastening element (8), wherein the pneumatic cylinder (7) comprises a piston surface with which the upper end face of the tie rod (3) can be acted upon, wherein the tie rod (3) has, at its end section opposite the pneumatic cylinder (7), a receiving geometry (11) in the form of a cylinder screw, and wherein the connection plate (2) has a receiving geometry (9) in the form of an elongated hole in such a way that the connection plate (2) can be suspended on the tie rod (3), in that this receiving geometry (9) in relation to the longitudinal axis of the tie rod (3) passes in the radial direction from a section (A) with a first open cross section in the form of the receiving geometry (11) formed as a cylinder screw on the tie rod (3) into a section (B) with a second open cross section which has a narrower contour opening than the first open cross section and an undercut, and wherein the inner installation space from the undercut has a contour in the form of the cylinder screw (11) formed on the tie rod (3).

The invention relates to an arrangement of a flow measuring device with a testing device. The flow measuring device comprises an inlet section and an outlet section. A rotor is arranged between the inlet section and the outlet section. The rotor is designed for a rotational movement in the event of a fluid flow between the inlet section and the outlet section. At least one indicator element is arranged on the rotor. The flow measuring device further comprises a measuring element, which is adapted to detect a movement of the indicator element. The indicator element comprises a magnetic material. The testing device is designed to set the rotor in rotational motion, preferably without contact.
