FIELD: measurement equipment.
SUBSTANCE: device, in which a harvested crop is transported with a conveyor, comprises the first measurement device for weighing of the conveyor with the transported harvested crop, the second measurement device for detection of the harvested crop volume, transported with the help of the conveyor, and a computer, which is connected with the first measurement device and the second measurement device, and which is engaged to determine mass density of the harvested crop by means of measured values of the first measurement device and the second measurement device. At the same time, according to the invention, the computer is made with the capability of engagement in order to detect mass flows, which, in case of flows that exceed the preset threshold value, are based only on current measured values of the first measurement device (56), and in case of flows that are below the threshold value, are based on current measured values of the second measurement device and on the value of mass density of the harvested crop, which for the latter flow exceeding the threshold value is defined by means of measured values of the first measurement device and the second measurement device.
EFFECT: increased accuracy of detection of a mass flow of harvested crops also in case of low flows.
