Solid-state liquid level sensor from Adafruit.

Wartość na wyjściu rezystancyjnym jest odwrotnie proporcjonalna do wysokości płynu.

The value on the resistive output is inversely proportional to the height of the liquid.

Working principle

The cover of the eTap sensor compresses under the hydrostatic pressure of the fluid in which it is immersed. This causes a change in resistance, which corresponds to the distance between the top of the sensor and the fluid level. The value on the resistive output is inversely proportional to the height of the fluid - the lower the fluid level, the more the resistance increases; the higher the level, the resistance output decreases..
