ABSTRACT:
The invention relates to a device for preventing overfilling of a plurality of fuel tanks (8) at a gasoline station, in the event that fuel tanks are filled simultaneously by multi-chamber tank vehicles (7). The fuel tanks (8) are equipped with filling level threshold indicators (3) linked to a transmitter (1) for wireless transmission of a signal. A receiver (2) mounted in the tank vehicle (7) is provided to control one or several tank valves. In order to ensure safe closure of the tank valves, the filling level threshold indicators (3) of the fuel tanks (8) at the gasoline station are connected each to a signal line (5) leading to a common interface (4). Only one transmitter (1) along with an interrogation control device is provided for connecting to said interface (4) and cooperates with the receiver (2) mounted in the tank vehicle (7). The receiver is connected to a control for receiving address-coded signals from the transmitter (1), said control being connected to an actuating device for selectively disconnecting the tank valves of the tank vehicle (7).
