Patent ID: 8186394

Claim:
A delivery control device for preventing errors in the choice of the fluid when delivering fluid to a container by means of a fluid delivery nozzle, the nozzle having an outlet tube that is introduced into a fluid delivery orifice of the container, the structure of the outlet tube being a specific function of the fluid delivered, comprising: a primary coil, fixed to the container in the vicinity of the fluid delivery orifice so that the outlet tube of the fluid delivery nozzle passes through it on its introduction into the fluid delivery orifice, a control and measurement electric circuit adapted to supply the primary coil with power so as to generate electromagnetic waves in the space inside the primary coil, detector means sensitive to the waveform of the currents or voltages that appear in the primary coil that distinguish the presence and the type of fluid delivery nozzle as a function of said waveform of the currents or voltages in the primary coil.
