Abstract
This device periodically isolates a sample of a beverage in production and determines the level of Carbon Dioxide present in the sample by the pressure temperature method. This system eliminates the overpressure in the line and then computes the carbonation level in the beverage to the same precision as standard laboratory instruments. The line pressure is often higher than the equilibrium pressure in the finished container by a significant factor (1.5 to 2) and is also fluctuating. By properly equilibriating the sample before testing these problems are eliminated.
