Non-Contact Liquid Level Sensors

DFRobot Non-Contact Liquid Level Sensors use capacitive sensing to detect liquid through non-metallic container walls without contacting the measured medium. The sensors help prevent corrosion, contamination, and material buildup when monitoring strong acids, alkaline solutions, toxic liquids, viscous substances, and other challenging media. One-touch automatic calibration adjusts sensitivity for the container material and wall thickness without manual tuning.
