SolidFlow 2.0 is a sensor especially developed for measuring the flow rate of solids conveyed in metallic ducts.
It has successfully been tested for online-measuring of:

  • all types of dust, powder and granulates
  • grain size between 1 nm and 1 cm
  • pneumatically conveyed materials or
  • in free fall after mechanical conveying systems
  • SolidFlow is wear-resistant and the commissioning is very easy.
  • Dust: ATEX II 1/2D Ex tD IP 65 T84°C
  • Gas: ATEX II 2G Ex d IIC T5/T3C
