As the name implies, there is a word "water level" in the Water level electrode, so it is a tool for measuring the water level, and the last two words are electrodes. It can be seen that it is inseparable from electricity, and the working principle of the water level electrode is based on water. Or the conductivity of steam is used to measure the water level, so as to send out specific water level data to the outside world. However, many water level electrodes have indicator lights, which will light up according to different resistances. People can also judge according to the number of indicator lights. The depth of the water level, this is the working principle of the water level electrode.
