Endress+Hauser Liquicap FTI51 Capacitance Point level detection

• Cost savings thanks to easy and fast commissioning as calibration takes place at the press of a button
• Reliable and safe measurement due to active build-up compensation
• Reliable and universal application thanks to wide range of certificates and approvals
• Short reaction time
• Material in contact with the process made of corrosion-resistant and FDA-listed materials
• Two-stage overvoltage protection
• No need for recalibration after replacing electronics

For liquids that tend to form build-up. Interface detection of different liquids. Two-point control (pump control) with just one process connection. Foam detection of conductive liquids.
