CARBOTEC sensors are applied for measurement the dissolved CO2
content in liquids, e. g. in carbonated soft drinks and beer. The measurement is performed in-line by regular abrupt localized decompression.
For determining the CO2
content,a sample is isolated from the main stream. When the pressure is abruptly reduced, the resultant pressure will differ from that of a non-carbonated liquid according to the volume of dissolved CO2
in the sample.continue reading →
