The Water level electrode often appears in the speedometer. In fact, the working principle of the water level electrode is well understood, and its role is huge.
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 level of 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 resistance sizes. People can also judge according to the number of indicator lights. The depth of the water level is the working principle of the water level electrode.
