FAQ

Q1: Can capacitive level sensors measure highly conductive liquids, such as salt water? ❯

Yes. Conductive liquids will not harm capacitive measurements. Even with high liquid conductivity, the sensor probe usually has an insulating layer to prevent direct electrode contact. As long as the change in dielectric constant is significant enough, accurate measurement is possible. For high-salt, high-acid, or high-alkaline media, PTFE or PVDF materials are recommended to avoid corrosion.

Q2: Are there any requirements regarding the material of the container for capacitive level sensors? ❯

Both metallic and non-metallic containers are acceptable, but metallic containers generally provide more stable measurements because they form a "natural second electrode." If the container is made of non-metallic materials such as plastic or glass, the sensor itself needs to form a complete capacitive circuit, thus requiring calibration or the use of a dual-electrode probe structure. As long as the installation method is correct, the container material will not affect the measurement reliability.

Q3: Can capacitive level sensors be inaccurate due to residue on tank walls? ❯

Possibly, but the impact is minor. If the medium is prone to scaling or wall adhesion, the buildup can alter the capacitance value, causing zero-point drift. Anti-scaling probes, PTFE sheaths, or installation locations away from areas prone to scaling can be used. If scaling is severe, regular cleaning and recalibration are necessary to maintain measurement accuracy.
