LB 442 Mass Flow Measurement
for pneumatically conveyed or free-falling bulk materials

The bulk flow meter LB 442 is used for the mass flow measurement of pneumatically conveyed or free-falling materials.
LB 442 ensures a highly precise and stable measurement. Specifically developed for the bulk industry, it is extremely robust,
providing reliable measuring results for many years of operation.
The system is absolutely maintenance-free and does not require
recalibrations.
No Contact - Perfect!
The radiometric measurement system works completely noncontacting and is therefore not exposed to any wear and tear.
Neither temperature, variations in particle size, pressure nor
conductivity of the measured material affect the performance of
the system. The LB 442 can even be used in extremely dusty or
abrasive environments, where highly precise and reliable measurement results are achieved.

Fields of Application
LB 442 can easily be mounted
externally on existing pipelines,
chutes or on the discharge of
vibrator trays, transfer chutes,
screw conveyors etc. without
any modification of the conveyor system. The LB 442 mass
flow measurement can be used
for example to monitor truck
loads – further applications can

Radiometric Mass Flow
Measurement
Gamma radiation is directed
through the measuring point
towards a scintillation detector on
the opposite side of the pipeline.
When irradiating the pipeline, the
radiation is attenuated. Since the
measuring geometry is constant,
the resulting attenuation is directly
proportional to the solids concentration. In combination with the
material velocity, the required mass
flow can be accurately determined.
