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.

A system for remotely measuring and controlling the CO2 content of a beverage line liquid in a periodic fashion such that there are three computer controlled solenoid valves－the first valve for sample input, the second valve for sample output, and the third valve (equilibrium valve or timing valve)

A system for remotely measuring and controlling the CO2 content of a beverage line liquid in a periodic fashion such that there are three computer controlled solenoid valves－the first valve for sample input, the second valve for sample output, and the third valve (equilibrium valve or timing valve) for automatically zeroing a pressure transducer and relieving an overpressure in the line; wherein the third solenoid valve automatically zeros the pressure transducer for offset, atmospheric changes, and drift prior to CO2 measurement; and during said measurement, automatically bleeds the overpressure in the line for a predetermined period of time based upon the type of beverage being measured.
