Abstract

PURPOSE: To simplify the construction of a light emission diode display type liquid level meter for ready maintenance by employing light emission diodes in display.
CONSTITUTION: An AC low voltage is applied between one common electrode 2 and a plurality of liquid level sensing electrodes 3-1, 3-2,... set in length in response to the height of the liquid level to amplify very low current flowing when liquid surface makes contact with the respective liquid level sensing electrodes to thereby energize light emission diodes 5-1, 5-2,... elevationally arranged corresponding to the sensing electrodes. There are also added external connecting terminal 11 for producing liquid level sensing signal externally and sensitivity control resistor 10 for controlling the operation sensitivity.
