Endress Hauser Industrial Level Instrument E+H Liquicap FMI51 FMI51 Capacitive Level Transmitter for Chemicals

The Liquicap FMI51 is a capacitance continuous level transmitter with fully insulated rod or rope probe. It is particularly strong in media that tend to stick or coat probes (adhesives, slurries, polymers). The active build-up compensation and gas-tight feedthrough make it reliable for long-term use in tanks and silos.

• PFA/PTFE insulation – resists buildup and corrosion
• Active build-up compensation electronics
• Gas-tight feedthrough for safety
• Simple 2-point calibration
• Heartbeat Technology – in-situ verification
• Multiple output protocols
• Rod or rope probe flexibility

• Measuring Principle: Capacitance
• Measuring Range: Rod: up to 4 m; Rope: up to 20 m
• Process Temperature: –40 to +200 °C
• Process Pressure: Vacuum to 100 bar
• Accuracy: ±2 mm (rod probe)
• Probe Material: PFA/PTFE over 316L core
• Output: 4–20 mA HART, PROFIBUS PA, FOUNDATION Fieldbus
• Approvals: SIL 2/3, ATEX, IECEx, WHG

• Adhesive or sticky liquids
• Slurries and pastes
• Bulk solids with coating tendency
• Interface measurement in tanks
• Hygienic or corrosive media

Q: How does it handle buildup? A: Active compensation electronics ignore stable buildup.

Q: Rod or rope probe? A: Rod for shorter ranges, rope for taller silos/tanks.
