FIELD: agriculture.
SUBSTANCE: group of inventions relates to monitoring of level of filling the hopper. The monitoring system comprises a level sensor connected to the hopper to determine the specific control level of an agricultural product in the hopper and creation of a calibrating factor. The sensor of input determines the rate of intake of an agricultural product in the hopper. The conveyor is made with the ability to move the agricultural product from the hopper. The sensor of output provides a status indicator that indicates whether the conveyor is in the active state or in the inactive state during one or more evaluating time intervals. The data processor based on the status indicator determines the rate of outflow of the agricultural product. The data processor comprises a unit for evaluating the level for evaluation of proposed level of filling the hopper based on the rate of intake and the rate of outflow.
EFFECT: group of inventions provides high accuracy of indications of level of filling the hopper.
