Abstract: This overfill prevention system probe for tanks for transport of liquid fuels comprises a level detector mounted on a support that is fixed to the tank so that the detector is placed in the compartment at a maximum permissible filling height. The level detector includes a measuring sensor comprising a set of several electrodes and means for measuring the dielectric permittivity of a fluid present between the electrodes. The probe also comprises means for testing the satisfactory operation of the entire acquisition chain of the dielectric permittivity measurement of the fluid present at the electrodes.

Abstract: This overfill prevention system probe for tanks for transport of liquid fuels comprises a level detector mounted on a support that is fixed on the tank so that the detector is placed in the tank at a maximum permissible filling height. The level detector includes a measuring sensor capable of providing a redundant level measurement.
