Abstract of the Disclosure A system to safeguard an automatic fuel vending filling station from fraudulent use, by automatically preventing the delivery of more fuel than a predetermined monetary value. The amount deposited in the cash box (as determined by a conventional money tester) is communicated to a registration structure via a logic network having an input for each pump outlet or nozzle. Each such input is connected to a pulse generator driven by a volumetric device at the respective outlet for receiving counting pulses therefrom at a cadence proportional to the rate of fluid dispension, advantageously with interposition of a calculator converting the dispensed fluid quantity into its monetary equivalent. The registration structure controls a first circuit breaker for de-energizing all pumps upon being counted down to zero by the logic network in response to the counting pulses, the logic network having an output connected to a pre- settable counter for transmitting thereto a train of pulses corresponding to a monetary amount deposited in the cash box with the aid of an electrically driven money feeder. The presettable counter controls a scanned circuit breaker for de-energizing the money feeder as soon as the deposited amount equals the setting of this counter, thereby preventing the filling station from handling more than a certain amount of cash at a time.
