Abstract
A real-time measurement is made of the proportions of solid matter and pigment contained in an electrodeposition coating material in an electrodeposition coating material tank. The attenuation of an ultrasonic wave through the electrodeposition coating material and the density and temperature of the electrodeposition coating material are measured, and a real-time measurement is made of the proportions of the solid matter and pigment by means of calculating these proportions on the basis of the measured ultrasonic-wave attenuation, density and temperature. Furthermore, the composition of the electrodeposition coating material is controlled on the basis of the results of said measurement.
