ABSTRACT:
A method and apparatus for measuring the amount of air bubbles contained in liquid, in which the liquid is introduced in a closed space and is then twice pressed under different pressures to compress the air bubbles in the liquid in order to provide two liquids having different pressures, and the pressures of the two liquids are measured by a pressure gage to determine the amount of air bubbles. The apparatus comprises a container defining a closed space in which the liquid to be measured is introduced, a cylinder which is connected to the closed space and which has therein a movable piston, and a pressure gage which measures the pressure of the liquid.
