Radiometric measuring device for determining a mass flow rate

A method of determining a mass flow rate of a bulk material on a conveyor belt, comprising:

• detecting at least a portion of radiation emitted towards the bulk material on the conveyor belt, the radiation having at least partially traversed the bulk material and the conveyor belt;
• determining the mass flow rate of the bulk material based on the detected radiation;
• storing at least one measured value equation, the measured value equation representing a relationship between the detected radiation and a mass flow;
• and
• determining a correction equation based on at least one calibration measurement without bulk material on the conveyor belt, with which the measured value equation is corrected.
