Velocity measurement, material transport

SpeedFlow 2.0-Pipe

Velocity measurement in full cross-section version. Continuous velocity measurement in tube version for careful material transport. Measures in full cross-section.

Add to Compare
  • Continuous speed measurement of solids (powder, granules, dust ) in metal pipes
  • Measurement directly in the conveying stream / entrained flow
  • Measurement is completely independent of material
  • Sensor is made accordingly to the existing pipe diameter
  • Measurement without product contact
  • Plastic industry
  • Tobacco
  • Food
