Measuring techniques for density measurement

The proportion of solid matter in a liquid is determined with the help of density measurement.
Typical applications in the process industry are the measurement of acid and lye concentrations, the mixture density of abrasive or sticky liquids and the solid matter content of sludges and slurries.

VEGA uses two different physical measuring principles for density measurement

  • Differential pressure
  • Radiometric
