Level measurement
Liquicap FMI21

For continuous level measurement in conductive liquids

  • Liquicap FMI21 ©Endress+Hauser

Liquicap FMI21 is a simple and cost-effective rod probe for continuous level measurement for conductive liquids. High quality non-corrosive materials (carbon fibre, stainless steel) make it suitable even for aggressive liquids (e.g. acids and alkalis). Used in conjunction with the Fieldgate FXA320 (remote measured value interrogation using Internet technology), Liquicap is an ideal solution for Inventory Management Solutions.


  • Safe and reliable function regardless of tank geometry

  • No calibration necessary (factory preconfiguration)

  • High quality, non-corrosive materials (carbon fibre, stainless steel) for use in aggressive liquids

  • No moving parts in tank

  • Cost-effective solution for continuous level measurement

  • Optimized storage by simply shortening the probe rods on site

Field of application

The device is preconfigured from factory 0 to 100% to probe length ordered. It can be used as of a conductivity of 30μS/cm and the measurement is independent of the dc-value (dielectric constant) of the liquid. Suited for cistern measurements.

  • Process connection: Thread

  • Process pressure: Vacuum to 10bar (vacuum to 145psi)

  • Measuring range: Up to 2.5m (8ft)

  • Temperature: -40 to +100°C (-40 to +212°F)

  • International explosion protection certificates, overfill prevention WHG
