Acid, alkali, solvent and vapor conditions can attack standard wetted parts or seals.
Chemical tanks may generate foam, condensation or vapor that affects ultrasonic and some non-contact readings.
Explosion-proof or intrinsically safe versions must match the site classification and certificate requirement.
Sanitary or high-purity tanks may need flush diaphragms, clean process connections and compatible fill fluids.
WELK checks chemical name, concentration, temperature and wetted material before quotation.
Radar, guided wave radar, anti-corrosion ultrasonic, pressure level and lined magnetic gauges can be compared.
Certificate requirements are collected during RFQ instead of assumed from product titles.

Send chemical name, concentration, density, vapor condition, foam, temperature and pressure.
If the tank is hazardous, include area classification, gas group, temperature class and required certificate.
For sanitary or viscous liquids, specify connection standard, cleaning cycle and whether a flush diaphragm is required.
Operating limits vary by medium and installation - values above are typical ranges, confirmed per project.
Radar, anti-corrosion hydrostatic probes and magnetic gauges are matched to vapor, corrosion and process connection.
Yes, if the process seal, antenna face and connection materials are compatible with the acid and temperature.
Use it for narrow tanks, bypass chambers, interface duties or when a probe-guided signal is preferred.
Yes for suitable chemicals, but vapor, foam and corrosion must be checked.
Area classification, gas group, temperature class, medium and certificate requirement are needed.
We confirm the measurement principle and model.
