Field of application
Specifically developed for the food and beverage and life sciences industries, the Liquiphant FTL63 is compliant to all their hygienic requirements. The proven vibronic technology works reliably in all pumpable liquids, even where other measuring principles reach their limits due to changes in conductivity or dielectric constant (DC value), deposits, foam, turbulences or air bubbles. Therefore, the technology is the perfect substitute for float switches, capacitive or optical sensors.
Liquiphant FTL63 is used for point level detection in process and storage tanks as well as in pipelines.
Process temperature from -50 to +150 °C (-58 to +302 °F)
Viscosities up to 10,000 mm2/s (cSt)
Sensor length up to 3 m (10 ft)
Surface finish: mechanical or electropolished
International hygienic certificates (3-A, EHEDG, ASME BPE), contact material conformity with EC1935/2004, FDA, GB4806
International explosion protection certificates, overfill protection WHG, SIL
CIP/SIP
Benefits
Universal use in all pumpable liquids without media adjustment - proven vibronic measurement technology
High process and product safety through certified hygienic design (3-A, EHEDG, ASME BPE) as well as proven material conformity and traceability through declarations and certificates (e.g. EC1935/2004, FDA and cGMP)
Easy commissioning with plug & play functionality and minimized maintenance effort thanks to function test via test button or magnetic pin
Continuous diagnostics as well as traceable and documented on-demand verification without process interruption thanks to Heartbeat Technology
Intuitive operation via Bluetooth® Technology as well as optical process status indication via colored and bright LED
