A gasoline dispenser control and data system comprising a central office and a plurality of local stations, each station having dispenser control functions, data storage functions and communication functions. The station has a dispenser control mode and data entry mode. In the dispenser control mode a dispenser may be set to dispense gasoline, such dispensing of gasoline resulting in the production of pulses which are accumulated in a counter. The dispenser may then be reset for the next sale. Upon reset the counter is returned to zero, and the previous sale is stored in a temporary memory for recall and display, also being stored in two separate permanent memories, one of which is accessible to the station operator and the other of which is not accessible to the station operator. In the data entry mode the station operator can enter data into some but not all permanent memories. The station data system may be telephoned by the central office and each memory interrogated. The central office may also enter new data in the station data system. Means are provided for interrupting transmission for a limited time for operation of dispensers on a limited basis. Means are also provided for automatically entering data such as the amount of gasoline in storage tanks in the station memory, for 'in use' and 'ready' signals for each dispenser, and for an emergency off function.
