The LB 442 system is used in the precise mass flow determination of solid matter in a variety of conveyor systems. With many conveyor systems, the radiometric weighing system is the only suitable method for determining mass flow. The Berthold system can also be used to determine the mass flow in “free fall” in pipes or chutes.

The LB 442 provides both the flow rate as well as totaling the mass of solid matter over an individually selectable measuring range from 0-200 kg/h up to 0-10 000 t/h. With the LB 442, measurements can be taken directly after bunker, chute out-lets or transfer systems. From fine powders to large particles weighing more than 10 kg, the LB 442 measuring system is used worldwide.
