The Liquicap FMI21 rod probe is suitable for continuous level measurement of conductive liquids, with a simple design and economical, practical use. Made of high-quality corrosion-resistant materials such as carbon fiber and stainless steel, the probe can be used to measure corrosive liquids (e.g. acids and alkalis). Used together with Fieldgate FXA320 (remote measured value access via Internet technology), Liquicap provides an ideal inventory management solution.
Benefits
Special probe design ensures safety regardless of the tank geometry
No calibration required (0%/100% probe length preset at the factory)
The probe is made of high-quality corrosion-resistant materials such as carbon fiber and stainless steel, can be used in corrosive liquids and toxic water, and has been certified by WHG (German Water Resources Act).
No moving parts, long service life, reliable performance, no wear
Cost-effective continuous level measurement of conductive liquids.
The rod can be shortened on site for simple storage.
Application
The Liquicap FMI21 rod probe is suitable for continuous level measurement of conductive liquids with a conductivity greater than 30μS, and requires no calibration (0%/100% probe length preset at the factory). Above a conductivity of 30μS/cm, the measurement result is independent of the liquid DK value (dielectric constant). Also suitable for hazardous areas, Zone 2.
