Abstract
A method of and apparatus for the measurement of the degree of charging of a liquid synthetic resin component with a gas in which the flushing of the measuring column and the detection of the hydrostatic pressure are effected solely by control of the intake valve to the measuring chamber, a discharge valve at the bottom of an overflow chamber connected to the measuring chamber, and a three position valve connected to the top of the overflow chamber. In one position of this latter valve, a pressurized gas is applied to the overflow chamber to drive overflow liquid component back to the tank: in another position of this valve the column can be equilibrated with atmospheric pressure: in a third position this valve is closed.
