Algae Growth Causing False Alarms in Ultrafiltration Purifier Tanks? Non-Contact Capacitive Level Sensor Resists Biofilm

Ultrafiltration retains minerals but also provides nutrients for algae. In dark, humid tank conditions, a thin green biofilm forms within two months. Optical level switch lenses get covered, falsely reading "full" and stopping intake. Electrode probes raise hygiene concerns from metal ion leaching.

Xingkechuang's non-contact solution sticks to the tank outer wall. The capacitive principle judges liquid level — algae film and condensation ΔC are minimal and filtered out, only the real water level triggers. Shenzhen Xingkechuang Technology Co., Ltd.'s solution extends zero intrusion into the water body, making sanitation certification smoother for purifier brands.
