The method of analyzing is the same as used in most production laboratories. Values of pressure and temperature are electronically introduced in user 's concentration tables. From these proven tables the pressure exerted by a known volume of CO2 in a liquid at any given temperature can be found. Therefore if carbonated liquid at process temperature is isolated from the mainstream and the pressure is abruptly reduced to below atmospheric pressure the resultant pressure will differ from that of a non-carbonated liquid according to the volume of dissolved CO2 in the tested liquid. The ProcanDCD follows this principle giving in 10 to 20 seconds intervals (depends on type of product) new concentration values. Values of resultant pressure and temperature are used for calculation of the Vol% or g/l of CO2 in the beverage.

The ProcanDCD must be installed in a by-pass of the production line. The sample will be feed through the measuring chambre and at certain intervals it will be completely isolated from the process line. At the end of the cycle the measuring values are ready for calculation of the concentration. During the next step of the cycle the chamber will be flushed and prepared for the next step. All applied parts are made out of stainless steel or other corrosive resistant materials and can withstand all CIP procedures.
