PROCEDURE AND COATING COLOUR ANALYZER FOR ON-LINE ANALYSIS OF COATING COLOUR
A coating colour analyzer (20) is used for on-line analysis of coating colour with regard to air content, etc. that comprises a. a measurement vessel (21), b. means to remove a sample of coating colour from a flow of deaerated coating colour for a coater (I)5 which means comprises an inlet conduit (22) to the measurement vessel and an outlet conduit (23) from the measurement vessel (21), b. means for sealing the measurement vessel (21), which sealing means comprises a first valve (Vl) in the inlet conduit (22) and a second valve (V2) in the outlet conduit (23), c. means (24, V3) for exposing the sample of coating colour in the measurement vessel (21) to a predetermined increase of pressure that, when the sample of coating colour still contains captured air, decreases the volume of the sample of coating colour and increases its density, and d. means (28, 31) for determining the decrease of volume / increase of density at the predetermined increase of pressure. In order to avoid the need to decrease the volume of the measurement vessel (21) by use of moveable components in the measurement vessel (21), the increase of pressure is by means (24, V3) which apply compressed air in direct contact with the sample of coating colour.
