The FMI51 is the rod version. If a cable capacitive level transmitter is required, use the FMI52. For measuring light solids, use the FTC260.

The Liquicap FMI51/FM151 is a fully insulated rod probe for level monitoring in a wide range of liquids, and it also measures effectively in media prone to buildup and at extremely high temperatures. The measurement is unaffected by the dielectric constant (DC). Used together with the Fieldgate FXA320 (remote reading of measured values via Internet technology), Liquicap is the ideal choice for inventory management solutions.

Benefits:

• Compliant with IEC 61508, can be used in safety systems up to functional safety level SIL2

• Numerous certificates and approvals for reliable use and a wide range of applications

• No calibration required (factory preset). No calibration is needed when measuring media with a conductivity of 100 μS/cm and higher

• Process wetted parts made of corrosion-resistant, FDA-approved materials

• Menu-guided on-site configuration via plain text display (optional)

• Two-stage overvoltage protection

Application areas:

The instrument is unaffected by the dielectric constant (DC); liquids have a conductivity of 100 μS/cm, and multiple liquids can be measured without recalibration.
