Capacitive level gauges are indeed capable of measuring highly corrosive media, relying on protective coating materials for anti-corrosion performance.

Safety Operation Reminders
Cut off the power supply before disassembling the probe for cleaning or maintenance.
For storage tanks containing flammable, corrosive or high-temperature media, isolate the process pipeline, empty the tank and fully ventilate before any maintenance work.
Do not disassemble explosion-proof level gauges in hazardous areas without cutting off power.

capacitive level gauges can measure pure water level, but there are special points to note

Capacitive level gauges measure liquid/solid material levels based on the capacitance change between electrodes and media, featuring simple structure, wide adaptability, high temperature/pressure resistance, and strong anti-corrosion performance. Their main application industries are as follows:

Water separators, especially oil-water separators and gas-water separators, are essential industrial purification equipment widely deployed in compressed air systems, industrial wastewater treatment, fuel purification, petrochemical production and mechanical supporting fields.

Joint multi-parameter water quality analyzers integrate electrochemical sensing, optical spectrophotometry and automatic titration technologies to simultaneously detect physical, chemical and nutritional indicators in water bodies, widely used in environmental monitoring stations, municipal water plants, industrial wastewater stations and third-party testing laboratories.

Online moisture analyzers are critical real-time detection devices widely applied in food processing, pharmaceutical production, chemical materials, mining metallurgy, building materials and biomass energy industries

Water quality analyzers vary widely in detection principles, functional configurations, accuracy grades and application scenarios. Improper instrument selection often leads to insufficient detection accuracy, mismatched operating conditions, wasted equipment investment, or failure to meet environmental compliance and laboratory accreditation requirements.
