Abstract: A device for measuring the dust content of an air stream includes a supply line having an inlet opening for supplying the air stream toward a measuring chamber for measuring the dust content. An adjustable flow rate pump is configured for suctioning the air stream toward the measuring chamber. A first measuring system is configured for measuring the velocity, temperature, pressure, and moisture content of the air stream at the inlet opening. A second measuring system is configured for measuring the flow rate, temperature, pressure, and moisture content of the air stream in the measuring chamber. A third measuring system is configured for measuring the dust content in the measuring chamber.
