ABSTRACT:
The present invention relates to a new concept in measuring the dissolved gas levels in supersaturated liquid streams. In particular, the new device is specifically applicable to the measurement of carbonation levels in soft drinks. The measurement is made by permitting the beverage to escape from the pressurized container to atmospheric pressure through a thin tubing. The gas escaping from the supersaturated beverage separates the liquid stream into alternating gas and liquid segments. The relative long term average length of the segments is directly related to the CO2 content of the beverage. The instrument is simple to operate, inexpensive, and needs no calibration; it is easily adaptable to presently used laboratory equipment, and is useful in production process control.
