The invention relates to a fluid dose-measuring device for dispensing predetermined amounts of fluid from a fluid container, comprising a housing with a stationary and a moveable part, wherein the stationary part comprises a connector portion defining an inlet passage, which connector portion is connectable to the fluid container, wherein the moveable part is configured to engage with an actuator of a dispensing device, and wherein the housing comprises an outlet through which the fluid is to be dispensed, and an internal gear pump with an inner and an outer gear for transporting fluid from the inlet passage to the outlet upon actuation by the actuator of the dispensing device, wherein the moveable part is connected to the outer gear, so that actuation of the moveable part allows to rotate the inner and outer gear relative to the stationary part.

A method and apparatus are provided for controlling a fuel delivery system to limit acidic corrosion. An exemplary control system includes a controller, at least one monitor, an output, and a remediation system. The monitor of the control system may collect and analyze data indicative of a corrosive environment in the fuel delivery system. The output of the control system may automatically warn an operator of the fueling station of the corrosive environment so that the operator can take preventative or corrective action. The remediation system of the control system may take at least one corrective action to remediate the corrosive environment in the fuel delivery system. One or more sensors may be employed to signal proper operation of the remediation system.

A fluid product dispenser is sized to removably receive a product package containing a supply of the fluid product. The product package includes an internally integrated fluid pump, and the dispenser includes a drive unit powered by flow of a fluid. Flow of the fluid powers the drive unit, which in turn drives the pump internal to the product package, resulting in dispensation of the fluid product in a product/fluid ratio that is independent of the fluid flow rate.

An electric oil pump includes a base portion, a pump portion, a power supply, a mechanical switch and a pressure trigger. The base portion has a fluid passage. The pump portion is disposed on the base portion. The power supply is provided with an electric power to the pump portion. The mechanical switch is electrically connected the pump portion and the power supply, and has a pressing member. When the pressing member is not pressed, the mechanical switch is in a conductive state, and when the pressing member is pressed, the mechanical switch is in a non-conductive state. The pressure trigger is located between the mechanical switch and the fluid passage, capable of pressing the pressing member when the pressure in the fluid passage is above an upper threshold and releasing the pressing of the pressing member when the pressure in the fluid passage is below a lower threshold.
