Field: Measurement (Instruments)
Classification: CPC B  G | IPC B  G

Claim 17:
18. A system for determining a mass flow rate of a bulk material on a conveyor belt, comprising:
a conveyor belt;
a measuring device for determining a mass flow rate of a bulk material on a conveyor belt, including:
at least one detector configured to detect at least part of radiation of at least one radiation source that emits the radiation in a direction of the bulk material on the conveyor belt, the radiation having at least partially passed through the bulk material and the conveyor belt;
at least one evaluation circuit which is configured to determine the mass flow of the bulk material on the basis of the detected radiation;
at least one storage means which is configured to store at least one measured value equation, the measured value equation representing the relationship between the detected radiation and the mass flow; and
at least one electronic calculation means which is configured to determine, based on at least one calibration measurement without bulk material on the conveyor belt, a correction equation with which the measured value equation is corrected,
wherein the calibration measurement is performed after a belt of the conveyor belt is changed.
