Beer Monitoring System QUATROL.50B

The continuous online measurement covers by the Beer Monitoring System QUATROL.50B the following beer specific parameters: refraction number, density, CO2 value The system determines fast and highly accurate the refraction number and the density of beer, from which the following beer characteristic values are calculated according to the Balling method:

  • Alcohol in %vol and g/l
  • Original wort direct and calculated
  • Extract apparent and real
  • Degree of fermentation
  • Energy content in cal and kJ

The modular concept allows the installation of additional sensors, the adaption of the software and the connection of external PC or PLC systems. The QUATROL-system is adaptable to each plant structure and increases its capabilities with customers demand.
