Abstract

PURPOSE: To improve the measurement precision, by specifying the passage section area of the fluid supply link tube between the raw material tank and the measuring room.
CONSTITUTION: The passage section area of material supply tube 109 linking raw material tank 102 and measuring room 105 is equal to or larger than the section area of plunger 101. Therefore, when suction-side check valve 104 is opened and plunger 101 is moved to the right, liquid 103 is sucked and charged into measuring room 105 instantaneously according to movement of plunger 101 not to generate a vacuum pocket because the section area of material supply tube 109 is equal to or larger than the section area of plunger 101 which tries to generate the vacuum pocket. Consequently, suction and invasion of foreign matters such as air from the external due to existence of the vacuum pocket are prevented to prevent degeneration of liquid 103 and lowering of the measurement precision.
