Bulk Flow Measurement

The contactless measurement and the lack of moving parts, allow a precise determination of the mass flow without any wear to the systems components. This outstanding advantage is applicable on various mechanical conveying systems like:

  • belt conveyors
  • screw conveyors
  • troughed chain conveyors
  • steel plate conveyors
  • bucket conveyors
  • free fall in chutes or pipes

This makes a radiometric bulk flow measuring system particularly interesting for various applications.


Measuring Principle

The intensity of radiation, coming from a specially designed radiation source, is measured by a scintillation counter after it has passed the material and the conveying system. From the resulting measuring signal, which is dependent from the loading on the conveyor system and the product speed, the evaluation unit calculates the mass flow rate.

Nuclear measurement will not change the products being measured!



Measurement is independent of:
  • High temperature
  • High pressure or vacuum
  • Volatile & biohazard material
  • Corrosive material


Advantages
  • Contactless measurement
  • External mounting without modification of the existing conveyor system
  • Lowest source activity
  • No recalibration necessary
  • Highest level of repeatability
  • On line measurement
  • No moving parts low maintenance
  • Easy to calibrate
