Abstract
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.
Claims16
A fuel delivery system, comprising:
- an underground storage tank containing a quantity of underground storage tank contents comprising a liquid fuel product;
- a tank positioned closer to a grade level than the underground storage tank;
- piping fluidly connecting the underground storage tank with the tank;
- a pump positioned to convey at least a portion of the quantity of the underground storage tank contents to the tank through the piping;
- an underground storage tank probe including an underground storage tank temperature sensor positioned to sense an underground storage tank temperature of the underground storage tank contents;
- a tank probe including a tank temperature sensor positioned to sense a tank temperature of a quantity of tank contents;
- and
- a controller in communication with the underground storage tank probe and the tank probe and configured to compare the underground storage tank temperature to the tank temperature at a first time during a conveying time period during which the portion of the quantity of the underground storage tank contents is conveyed to the tank through the piping to determine a first comparison value at the first time, the controller further configured to compare the underground storage tank temperature to the tank temperature at a second time during the conveying time period during which the portion of the quantity of the underground storage tank contents is conveyed to the tank through the piping to determine a second comparison value at the second time, the controller further configured to determine whether the second comparison value is less than the first comparison value to determine whether the pump is functioning properly.
