When the electrodes of a conductive point level sensor make contact with a conductive fluid, a small alternating current starts to flow. The associated electronics then initiate a switching command. Conductive point level sensors find application across all fields of industrial instrumentation—for instance, as overflow protection, pump control devices, or dry-run protection systems.
The Advantages
Simple, robust, and cost-effective point level detection
Flexible installation of point level sensors in any orientation
Capability to detect multiple switching points within a single vessel
About Conductive Level Measurement
Conductive switches enable simple and safe point level detection in conductive liquids. Liquipoint is suitable for a wide range of applications. No calibration is required, and there are no moving parts inside the tank—ensuring a long service life, reliable operation, and freedom from wear or blockages.

Conductive point level detection with Liquipoint excels in applications ranging from secure inventory monitoring (for minimum quantities) and tank overflow prevention to two-point and multi-point control (such as pump control).
Conductive Measurement: Measuring Principle.The resistance between two measuring electrodes changes depending on the presence or absence of a medium. In single-rod probes, the electrically conductive tank wall acts as the counter electrode.
