Abstract

PURPOSE:To easily and exactly perform the density measurement which is free from an error due to influence of bubbles, by controlling the conduction between the pressure debubbling chamber and the pipe, by means of the valve, and also controlling the pressure to the pressure debubbling chamber. CONSTITUTION:A liquid flowing in the pipe 11 is made to flow into the pressure debubbling chamber 12 by dynamic pressure. And when the actuator 16 is demagnetized, the passage port 13 is closed by the valve part 17a of the plunger 17, and communication between the pipe 11 and the chamber 12 is cut off. When pressure is put through the pressure pipe 14, a liquid flowig into the chamber 12 is debubbled and the density which is not influenced by bubbles is measured exactly by use of the densitometers 15a, 15b, etc. Subsequently, when pressure is put on the chamber 12 through the pipe 14 by opening the valve 17a, the measured liquid in the chamber 12 is returned into the pipe 11, and when it is stopped to pressurize by the pipe 14, the liquid in the pipe 11 is replaced and made to flow into the chamber 12. Accordingly, the density measurement which is not influenced by bubbles can be peformed easily and exactly.
