式液面計。 In order to detect the liquid level in a container, the electrode is exposed on the surface of the glass lining layer of a glass-lined liquid level gauge that is inserted vertically into the container, and the conductor from the electrode is inserted inside the glass lining layer. An external electrode that is embedded in the electrode and led out to the outside, and compares the value of the current flowing between the upper measuring electrode and the lower reference electrode with the value of the current flowing between the lower pair of reference electrodes. A glass-lined electrode type liquid level gauge characterized by having a detection circuit externally connected to each electrode conductor.
