Liquid-level gauge

Liquid-level gauge
Since measuring liquids with a direct voltage quickly leads to catalysis effects and corrosion, the gauge uses a rectangular voltage. The gauge is intended primarily for measuring the level in a rainwater reservoir, but can, of course, also be used for measuring other kinds of liquid. In the prototype, eight sensors in the reservoir were used. Placing these sensors at well-thought-out locations will minimize any errors in the measurements.
