Introduction water bottom measurement

The water bottom probe is based on a capacitive measurement principle. The probe is one plate of the capacitor
and earthed, electrically conducting parts as water and the tank shell, is the other plate. A change in water level is
detected by the water bottom probe as a change in capacitance.
