CO₂ Measurement in Liquids Using Pressure and Temperature
 
CARBOTEC TR-PT measures dissolved carbon dioxide in carbonated beverages such as beer, sparkling wine and soft drinks. The CO₂ content is determined from pressure and temperature measurements in the measuring chamber.
 
Measuring Principle
 
Carbonated liquid flows through the sensor head. The measuring chamber is closed several times per minute and its volume increases abruptly. This creates a gas phase. The equilibrium pressure is used together with the temperature to determine the CO₂ content.
 
Applications
 
 
 
Beer
 
 
Sparkling Wine
