The pompistes use graduated jogging to appreciate the volume of fuel in the underground tanks but these values always prove erroneous. It will be for us in this project to automate this system so that the pump attendant will only consult an HMI (Human Machine Interface) on which will be displayed all underground tanks and their fuel level and volume time real. The IHM will be able to communicate via the internet with the smart phone of the chief station through an application to inform him about the details of fuel consumption according to each quarter; also inform the general management of fuel sale transactions at a distance (volume consumed, volume remaining). Thank you
