Hot Wort Density, Extract and Evaporation Rate Online
 
RHOTEC EVAP VZ continuously measures hot wort density with high accuracy. Using a polynomial specific to the liquid, the sensor determines concentration in °Plato or percent extract.
 
Measuring Principle
 
Density measurement is based on the oscillating U-tube principle. Continuous measurement of the increase in concentration also determines the evaporation rate. This allows wort boiling to be controlled according to the required total evaporation.
