The Liquicap FTI51 uses a rod probe and can be used for limit detection of highly viscous liquids and liquids prone to buildup, as well as for interface and foam detection of conductive liquids. The FTI51 has buildup compensation for reliable measurement. The probe has obtained international approvals from various relevant industries and has a wide range of applications. Wetted parts use corrosion-resistant materials and FDA-approved materials to meet the highest safety standards.
Advantages
Fast and simple calibration and commissioning by key operation
Various approvals and permits for a wide range of applications
Wetted parts use corrosion-resistant materials and FDA-approved materials
Two-stage overvoltage protection prevents vessel discharge (gas discharge tube + protective diode)
Short response time of the measured value
No calibration required after electronics replacement
Automatic electronics monitoring
Areas of application
The Liquicap M FTI51 is preferably used in the following measurement applications:
Applications with high viscosity and buildup tendency
Interface detection between different liquids (e.g. oil/water interface)
Foam detection of conductive liquids
The probe has a robust, proven construction (self-sealing cone) and can be used in applications from vacuum to overpressure up to 100bar
