OPTIFLUX 4100

KROHNE OPTIFLUX 4100: Robust electromagnetic flowmeter engineered for abrasive and corrosive liquid applications.

The OPTIFLUX 4100 delivers precise electromagnetic flow measurement across demanding industrial environments where abrasive slurries and chemically aggressive media are present. With selectable liner materials including PFA, PTFE, polyurethane, hard rubber, ETFE, and soft rubber, the meter adapts to your process chemistry while maintaining measurement accuracy. Operating reliably from -40°C to +180°C at pressures up to 40 bar, it supports multiple output options—4-20 mA, pulse, frequency, status signals, and HART® digital communication—enabling seamless integration into control systems. Certified across ATEX, IECEx, FM, CSA, FDA, and leading marine classification societies, the OPTIFLUX 4100 meets international standards for process automation, hygienic applications, and offshore operations.
