Point Level Detection for Difficult Liquids
Liquicap FTI52 is designed for applications where the liquid itself makes level detection more difficult. Its rope probe configuration makes it suitable for larger measuring ranges, while active build-up compensation helps maintain reliable switching even when material accumulates around the probe.
Designed for High-Viscosity and Build-Up Forming Media
Highly viscous liquids can leave deposits on a sensor and gradually affect measurement performance. The FTI52 is specifically designed for these conditions, making it a practical choice for liquids that tend to form build-up.
More Than Basic Level Switching
The FTI52 can be used for several point-level functions, including maximum or minimum level detection, two-point pump control, interface detection, and foam detection of conductive liquids. This makes one sensing principle suitable for a range of process control tasks.
Long Rope Probe for Large Measuring Ranges
With a sensor length of up to 12 m, the FTI52 can be used in deep tanks and vessels where a compact point-level probe would not be sufficient. Different process connection options, including threads, flanges and hygienic connections, allow the sensor to be adapted to different installations.
Reliable Under Challenging Process Conditions
The FTI52 is specified for process temperatures from -80 to +200°C and pressures from vacuum to 100 bar. The process-contacting materials are corrosion-resistant and FDA-listed, while a range of international certificates and approvals is available depending on configuration.

FAQ
What type of level measurement is the Liquicap FTI52?
The FTI52 is a capacitance point level switch. It detects whether the process medium has reached the defined switching point rather than providing continuous level measurement.
Is the FTI52 suitable for viscous liquids?
Yes. It is specifically designed for highly viscous liquids and media that tend to form build-up, with active build-up compensation to improve reliability under these conditions.
How long can the FTI52 probe be?
The rope probe can be configured with a sensor length of up to 12 m, making it suitable for deep tanks and vessels.
Can the FTI52 detect an interface?
Yes. The FTI52 can be used for interface detection between different liquids, provided the application meets the required electrical properties for capacitive measurement.
Can it be used for foam detection?
Yes. The FTI52 can be used for foam detection of conductive liquids.
What are the process temperature and pressure limits?
The official product specifications list a process temperature range of -80 to +200°C and process pressure from vacuum to 100 bar.
Does the FTI52 require calibration?
The FTI52 is designed for straightforward commissioning, with calibration performed using a push button. Endress+Hauser also states that recalibration is not required after replacing the electronics.
What process connections are available?
Depending on the selected configuration, the FTI52 is available with threaded, flanged and special hygienic process connections.
