12 Volt Toilet Tank Refiller:

Adjustment Free Inclinometer operates on 2.7V: 04/24/97 EDN-Design Ideas

Fluid Level Detector:

Water Level Sensor:

Water-Level Sensor Uses Hysteresis: 08/21/00 Electronic Design - Ideas for Design / A low-voltage electronic circuit that senses upper and lower water levels is often used for alarms and sump-pump activation. Since an electronic sensor has no moving mechanical parts, it eliminates problems with corrosion and wear and tear.
