Abstract: An anti-theft device prevents tampering with a diesel fuel dispenser. The device bars access to a pulser even if a cover of the dispenser is pried back or removed. A housing formed of plate steel substantially surrounds the pulser and is secured to the frame of the dispenser in three places so that about one-half hour is required to remove the device, even after a cover has been fully removed from the dispenser. This allows ample time for a station operator to observe that a theft is in progress. Three bolts are used to secure the device to the frame of the dispenser. Advantageously, all three of the bolts are placed into pre-existing openings so that no new openings need to be drilled as a part of the installation process. Only one pre-existing bolt of the frame is removed and reinstalled during the installation procedure.

The SPC receives product selection information from the site controller and activates the relay connected to the pump in the storage tank containing the selected product, whereby the selected fuel product is pumped to the selected dispenser.

Abstract: A device for dispensing multiple fluids in, for instance, a vehicle service facility is provided with a plurality of control modules. Each of those modules is capable of being connected to a number of pumps, a number of solenoid valves and a number of meters. This system may be set up such that to dispense one fluid a pump may be turned on from a first control module, that pump being connected to a valve connected to a second control module and even a meter connected with a third module. Of course, the pump, valve and meter 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 minimizes the amount of wiring 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 and outputting of data for billing and record keeping.
