Abstract
A method of determining a characteristic of a fluid in an apparatus for applying a coating medium to an object, the apparatus including a fluid line; an outlet; a first coating medium source; a second coating medium source; a cleaning medium source; and a valve arrangement configured to independently bring each of the first coating medium source, the second coating medium source and the cleaning medium source in communication with the outlet through the fluid line; where the method includes conducting a fluid through the fluid line, the fluid including the first coating medium, the second coating medium and/or the cleaning medium; sending ultrasonic waves to the fluid in the fluid line; sensing echo signals induced in the fluid by the ultrasonic waves; converting the echo signals to electronic response data; and determining a parameter value of at least one parameter of the fluid in the fluid line based on the electronic response data.
