PURPOSE:To surely detect only the electrostatic capacity of a liquid storage in a container so as to surely detect the level of the liquid inside the container. CONSTITUTION:A metallic tube 12 is mounted to a tube 6 located inside a sampling arm 1 and is connected to the ground so as to stabilize the value of the electrostatic capacity of a liquid inside the tube 6 and further to reduce noise transmitted through the liquid inside the tube 6, the electrostatic capacity being applied to a probe 2. |
