<p>A fuel dispensing system includes a manifold (38) for receiving one or more grades of fuel at individual input ports and a plurality of output ports. The output ports are each connected to individual input ports of selection valves (13, 17 and 21), the latter having output ports connected to inlets of nozzles and hose assemblies (23, 25, 27 and 41). A controller (29) is included that is site programmable for designating a particular hose/nozzle assembly for dispensing a particular straight grade or blend of fuel. The controller (29) is responsive to the selection of a given nozzle (41) by a user for energising and controlling one or more flow control valves (5, 7), and the selection valve (13, 17 or 21) associated with the selected nozzle, for delivering the required grade or grades of fuel to the manifold (33) for dispensing the grade of fuel associated with the selected nozzle, in a desired amount under closed loop control. <IMAGE></p> |
