2.1 Use and Function of the Bulk Flow Meter
The radiometric Bulk Flow Meter LB 442 can be used to determine
the load
□ on conveyor belts
□ on screw conveyors
□ on chain conveyors
□ on troughed chain conveyors
□ during free fall.
The measurement can be carried out directly on the conveyor sys-
tem or – in case of free fall measurement - at the discharge sta-
tion.
Special instrument configurations and calculations allow adapting
the radiometric bulk flow measurement to the local situation and
the conditions of the product being measured:
a) Instrument configuration (Operating modes)
□ Measurement at constant belt speed
□ Measurement with tachometer
□ Measurement with moisture compensation
b) Measured value
□ Conveyed material
□ Load
c) Selection of measurement mode
□ Continuous measurement
□ Discontinuous measurement
- Batch operation via keyboard (press <run> button)
- Batch operation via digital input
d) Result Output
□ Live on LCD display for load and quantity
□ Current output 0/4 - 20m/A for load
□ Pulse output for load
□ Minute printout
□ Shift printout
