What are Capacitive Liquid Level Sensors? – Reventec
As the liquid level fluctuates, so does the amount of stored energy. The higher the liquid, the greater the capacitance. The lower the liquid, the lower the capacitance. Capacitive liquid level sensors contain no moving parts that may degrade over time. They can be used in any orientation whilst maintaining accurate measurement.
