Measuring technique for flow rate measurement

Flow rate measuring instruments measure the amount of substance that flows through a pipe cross-section per time unit. The measured quantity is outputted as mass or volume. Typical flow rate applications measure gases, vapours and aggressive or viscous liquids in pipelines as well as bulk solids on conveyor belts.
VEGA uses two different physical measuring principles for flow rate measurement:
  • Differential pressure
  • Radiometric
