Abstract

PURPOSE: To prevent leakage in a seal part due to the pressure difference between the inside and outside of a measuring chamber by a method wherein a measuring back side chamber provided on the back side of a measuring chamber is connected to a sealed container by means of a linking pipe, and the pressure on the back side of the measuring chamber is made the same as that of the sealed container.
CONSTITUTION: When, by opening input side open-close valve 9 and air vent pipe open-close valve 15, piston 19 is moved upward to upper measuring end a by cylinder 17, liquid 2 in vacuum container 1 is filled into measuring chamber 18 from intake pipe 5. Next, when, by closing valve 9 and opening outlet side open- close valve 10, piston 19 is moved down by cylinder 17, liquid 2 in measuring chamber 18 is discharged to part 8 to be supplied via transport pipe 7. In this case, since measuring back side chamber 23 and vacuum container 1 are linked via linking pipe 12, no large pressure difference occurs between both sides of gland packing seal 21 of measuring back side part 11 and liquid seal 22, so that leakage from the seal part can be prevented.
