Liquicap M FMI51, FMI52

The Liquicap M compact transmitter is used for the continuous level measurement of liquids. Thanks to its robust and tried-and-tested construction (self-sealing cone), the probe can be used both in vacuums and in overpressure up to 100 bar. The sealing and insulation materials used allow operating temperatures of –80 °C to +200 °C in the medium container.

The measurement is independent of the dielectric constant (DK) as of a liquid conductivity of 100 μS/cm. In this way, various liquids can be measured without the need for recalibration.

Used in conjunction with Fieldgate (remote measured value interrogation using Internet technology), Liquicap M provides an ideal solution for inventorying materials and optimizing logistics (inventory control).


  • No calibration necessary for media with a conductivity
    of 100 μS/cm and higher. The probes are calibrated to
    the ordered probe length on leaving the factory (0 % to
    100 %). This makes easy and fast commissioning
  • Menu-guided local configuration via plain text display
  • Universal application thanks to wide range of
    certificates and approvals
  •  Use also in safety systems requiring functional safety to
    SIL2 in accordance with IEC 61508
  • Material in contact with the process made of
    corrosion-resistant material and FDA-listed materials
    for wetted parts
  • Two-stage overvoltage protection against discharge
    from the container (gas discharger + protective diodes)
  • Electronics can be switched for media forming buildup
  • Short measured value reaction time
  • No need for recalibration after replacing electronics
  • Automatic monitoring of electronics
  • Monitors damage to insulation and rod breaking or
    rope tearing
  • Suitable for interface measurement
