Method for obtaining a height of a material stacked in a coke oven

A system for obtaining a parameter representative of a height of an upper surface of bulk coal stacked in a coke oven with respect to a reference plane, comprising:

• a leveling bar intended to be moved within the coke oven in a plurality of successive locations with respect to the upper surface, and
• at least one assembly fastened to the leveling bar and including:
• a sensor intended to be above the upper surface at an operation distance from the reference plane and to form a capacitor with the bulk coal, the capacitor having a capacitance, and
• a device for providing at least one capacitance signal representative of said capacitance, and
• a calculator,
• the assembly being suitable for providing at least one distance signal using the capacitance signal, the distance signal being representative of a distance between the sensor and the upper surface along a vertical direction,
• the calculator being adapted to calculate said parameter using the distance signal and the operation distance.
