Abstract
Customer dispensing of either unleaded or one of two or more grades of leaded gasoline products is selected by rotatable selector knobs located on the dispenser housing. Individual meters are operative by the leaded and unleaded dispensing systems which are hydraulically isolated from each other. The separate selector knobs are associated with each of the leaded and unleaded dispensing systems and are effective when actuated to render the other system inoperative by an imposed mechanical interlock. Bothe meters operate a common computers for calculating the transaction data of each dispensing sale.
