Measurement apparatus for mass flow detection of harvested crops

Measurement apparatus for detecting mass flow of harvested crops (68) conveyed by way of a conveyor (38), comprising: A first measurement device (56) for weighing the conveyor (38) with the conveyed harvested crops (68), a second measurement device (58) for determining the volume of the harvested crops (68) conveyed by the conveyor, and a computer device (54) for determining the mass density of the harvested crops (68). It is proposed that the computer device (54) be operable for determining and outputting mass flows based on the current measurements from the first measurement device (56) when flows are above a pre-determined threshold value, said mass flows otherwise being based on the current measurements from the second measurement device (58) and on a value for the mass density of the harvested crops determined for the flow last exceeding the threshold value.
