Bulk Flow Meter

The radiometric measurement of mass flow is carried out absolutely non-contacting and non-intrusive. Our belt weighers are applicable on a wide range of mechanical conveying systems like

  • Belt conveyors
  • Screw conveyors
  • Chain conveyors
  • Vibrating conveyors

Moreover they are used to monitor the mass flow of pneumatically conveyed or free-falling materials. They are easy to install on existing systems and provide a reliable and maintenance-free operation.


The LB 442 bulk flow system is used for the precise determination of mass flow in the bulk industry. The non-contacting, non-intrusive radiometric belt weigher is characterized by an excellent accuracy and reliability. LB 442 is very robust with no moving parts. Maintenance is not required.

MicroPolar 2 LB 567 is predestined for applications with constant measuring conditions (e.g. constant particle size, bulk density etc.) The measurement is carried out without the need of a radiometric unit. In combination with a height sensor the system allows for a compensation of varying bulk heights on the conveyor belt.
