<p>A device 10 for dispensing multiple fluids in, for instance, a vehicle service facility is provided with a plurality of control modules 32a, 32b, 32c. Each of those modules 32a, 32b, 32c is capable of being connected to a number of pumps 14a, 14b, 14c, a number of solenoid valves 26a, 26b, 26c and a number of meters 24a, 24b, 24c. This system may be set up such that to dispense one fluid a pump 14a, 14b, 14c may be turned on from a first control module 32c, that pump being connected to a valve 26a, 26b, 26c connected to a second control module 32a and even a meter 26a, 26b, 26c connected with a third module. Alternatively, any two or more of the pump 14a, 14b, 14c, valve 26a, 26b, 26c and meter 24a, 24b, 24c may, if desired, all run off of the same module as well. By user programming, the user selects connected sets for each fluid. This architecture minimises the amount of wiring 46 and other connections as different modules may be closed to different parts of the plumbed section. Provision is made for security on the operator pendants 40 and outputting of data for billing and record keeping. <IMAGE></p> |
