Electromagnetic Flowmeters KROHNE
KROHNE electromagnetic flowmeters are reliable instruments for accurate volumetric flow measurement of conductive liquids (conductivity ≥5 µS/cm) across a wide range of applications: from simple processes to custody transfer and safety systems. They are insensitive to viscosity, density, pressure, and temperature of the medium, handle solid contents up to 70%, and feature liners made of various materials (PP, PTFE, rubber, ceramic) for aggressive and abrasive liquids. Size range: DN2.5 to DN3000, accuracy up to ±0.2%, with advanced diagnostics, certifications (OIML, MI-001, SIL 2/3), and digital interfaces.
